I just never see it enable 4K even I m viewing images with gallery app.
So I just want to force it for better experience.

I'm not convinced, if this would be visible. Probably depends on your visual acuity.
Mine is not the best, and for the life of me I can't see the difference between 1440p and 1080p on such a small screen.

There IS it, I ve paid for it, and I WANT it.
And experience will be different for me when viewing large size image in 1:1 scale.
It is just like refresh rate, since there r people cannot get the difference between 120hz and 60hz(or lower). But you cannot just disable higher refresh rate FOREVER just because there r some people cannot distingurish.

It's also to remove unnecessary downscale/upscale when watching a 4k movie. Since most app view the screen as a QHD one, VLC for example, will render a 4k video as a QHD one by downscaling it, then the phone will upscale it back to 4K.
Sure you will probably not see a lot of difference with native 4k as the upscaling technology from Sony is pretty good and you still have the 4K screen resolution giving extra sharpness.
Also, what some people seems to forget, is that the image displayed will always be 4K on this screen, a FHD image will be upscaled to 4K by the phone, and the higher pixel density make it far better than the same FHD content on a QHD screen especially for AMOLED screen that are somewhat blurry on the edge due to the subpixels arrangement.
This being said, you can put the screen in native resolution all the time, just going in the developper option and setting the screen minimal width to 1644pixels to match the 1644*3840 pixel resolution. Doing this, VLC that I tried perfectly render a movie in 4K, but your overall UI is ****ed up and you can barely use the phone. That's not what is wanted. Sony is just boring us for 4 generation with its 4k white list apps. I don't even know what is the recommanded app to watch their 4k HDR spiderman extract.
It's stated that the screen only runs at 4k in certain apps and scenarios, Theres no option to change that.
More accurately: The phone only render graphic at 4k in certain apps and scenarios*
The screen always runs at 4K since it's hardware and number of pixels can't physically be changed. The phone upscale every content to 4K all the time but render some whitelisted app directely in 4K. Still better than proper 2K as the pixels are smaller, but also mean your 4K videos on VLC will be downscaled to 2K by VLC then upscaled back to 4K by the phone, only because Sony didn't whitelist VLC that is perfectly able to run native 4K.
I almost have the same question, but instead of 4K I want to set a global 2K resolution.
4K is way too overkill, but 2K is the best middle ground between display clarity and battery life.
that is what you basically have, 99% of the time your phone won't render 4k. Doing that for all scenarios in which things are rendered in 4k would make absolutely zero sense because then they would need to be upscaled again to fit the 4k reselution

When recording in 1080p using the camera it is zoomed in. When using 720p you can see a lot more in the picture, where as 1080p seems to zoom in on the central object.
Now I was just wondering is it possible to mod this to make 1080p video record without being zoomed in (like how 720p does it) or is it impossible and it has to work that way ?

Check out the video recording review in gsmarena.com
http://www.gsmarena.com/samsung_i9100_galaxy_s_ii-review-597p9.php
Here's a thread about it if you want more detail.
http://forum.xda-developers.com/showthread.php?t=959475
when the sensor chip (the camera) cannot crank for example 30FPS at 1080P resolution, "zooming" is a trick.
The sensor has less surface to scan with the zooming and can then crank out the said fps at said resolution.
The exynos chip however does "real" 1080p encoding and the image is really 1080p, but appears zoomed, and therefore contains slightly less details than if the sensor did not zoom (since parts of the field of view are not viewable)

So would it ever be possible to have 1080p video without 'zooming' by modding the firmware/ in a custom rom?
Or is it hardware limitation ?

Physical Hardware limitation
Native res of sensor = 3264x2448
HD Video = 1920x1080
3264 / 1920 = 1.7
so the only way to record 1920 is to bin the .7 thus cutting out much of the screen.
now 720p HD only has a horizontal res of 1280 that goes into said sensor 2.55, so you only need to cut out the .55 (less than full hd) and then read alternate pixels and bin the rest.
Hope that makes sense

I think that even binning the 0.7 factor should give a better result than the actual "zoomed in" effect. In the other hand whe should have the zoom function at 1080P resoultion too.

Humm... i'm still dubtfull about this limitation. Correct me if i'm wrong, but i think that the htc sensation is able to apply digital zoom @ 1080P, and it should have an 8Mpixel camera too, isn't it?
I can't post a link but if you searc for "HTC Sensation takes FULL HD 1080p videos " in youtube you will find a video taken with htc sensation with digital zoom!
I don't think that the galaxy s2 hardware is unable to do the same thiks that htc sensation does...
Oh, digital zoom is easy, but a bit pointless. So no point zooming if your source resolution drops, why not record native at the lower res and increase on pc? You will get better result that a phone attempting bilinear calculations .. So probably excluded cause of it being pointless.

Hi
digital zoom during video recording is not applied by a simple bilinear calculation. Its quite the opposite:
No zoom -> use the whole sensor area and then "downsample" it to obtain the desired dimensions
Zoom->Sample the exact dimension from the center of the sensor.
Infact, if you watch two videos of the same scene taken with the sgs2 720P and then 1080P, you will notice that the 1080P gives a zoomed effect, becouse samsung only uses the rectangle on the center of the sensor to sample the frames, while with 720P uses the whole sensor area.
Power limitations? Unskilled Samsung's engineers? Who knows..

I don't think that it's neither power limitations or unskilled samsung engineers. At 1080p, it uses most of the sensor, so zooming in will decrease the quality of the image to the point of being pointless at filming 1080p.
The reason why 720p uses the entire sensor area is because it does something called pixel binning. It uses the adjacent pixels to determine which color/info is more accurate (so a single pixel in the middle uses the ones around it to determine which color is closer to the actual source).
See here for more info:
http://www.svi.nl/PixelBinning
With pixel binning, you get less noise but at a cost of lower resolution. Therefore, they implemented zoom for 720p and the reason why 720p uses the entire sensor.
So the reason for why the 720p uses the entire sensor and 1080p only uses a section IS due to hardware limitations. 1080p needs at least a 12.4MP resolution for pixel binning.
As there is pixel binning, 720p will produce higher quality zooms than if 1080p could've zoomed using crop and bilinear enlargement (which will create pixelated images). That is why I assume they didn't include 1080p zoom - for quality purposes.
BTW - pixel binning is a technique also used by the iPhone 4.

Thats wrong! It's only correct if the sensor has the physical resolution that surpasses the target res by 2 exactly! Look at my previous post, I explain it a bit better. Your taking about sensor crop and pixel binning, not digital zoom.
Oh and bilinear is not simple, when you think of the amount of subpixel influence you have to create.
Neways, point is digital zoom creates pixels from thin air, well, programatically. So the detail is not present, hence why digital zoom is a consumer buzz than a valued feature.
Thanks for your replies guys. I would like to bring two more arguments for my theory:
1) The 720P recordings that we can find in the net shows a low quality zoom
2) In the other hand, there are some videos taken with the htc sensation that shows an almost perfect zoom @ 1080P
The question is:
if the htc product uses virtually the same sensor of the sgs2, how can they implement the zoom??
Here a video sample with digital zoom @1080P:

The answer is: Digital Zoom lol
Tis easy to see in the video that detail is lost, pixel get bigger then filtered etc. So Digital Zoom is a software feature, not hardware!
Also people seem to forget a few very important things regarding capture quality, the bitrate of the encoding profile in use. From what I see the sgs2 has a variable 10-14mbit profile active for full HD. Some of my pro cameras use 35-50mbit. So I'm going to look into how to mod this if i can since the hardware should be able to handle a higher rate, busy at the mo though.
at the end of the day though, tis a phone, if you want really good quality get a pro sumer hd cam, or a 5dmk2, or if you won the lottery get a Red Epic and shoot 5k res at 1000's fps. However none of those have mail/chat or phone capabilities
for 1080p are taken 1920x1080 pixels from the center of 8Mp sensor... (in this manner there is a "zoom effect" of about 2x and less view)
for other resolutions are applied pixel binning tecnhique (all pixel from sensor are used, and is scaling from 8mp to output video resolution)
take original pixels produces better quality (because are original pixels and not scaled), but less signal/noise ratio (but, because galaxys2 sensor is good, noise is low also if you take original pixel and don't use pixel binning that increases signal/noise ratio)..
also, use original pixels and don't use pixel binning, requires less power (in this manner you can have 1080p video at about 30fps and high bitrate)

Ok deanwray, you're perfectly right, but i would prefer to choose by myself if i wish to use the zoom or not, awared that if i use the digital zoom, the quality will be affected. In the other hand, in this way, the 1080P video would have better field of view (instead of the zoomed effect we have now) and less noise.
About the bitrate: maybe it's possible to raise it to 20Mbit, but i think that going above this limit is quite difficult. According to me, it's better to implement the zoom in 1080P and a better audio recording.
I was thinking: if they're unable to implement such features... how can we hope to obtain higher bitrates.. ?

If it's not firmware (camera firmware) limited, there are calls in the android sdk to set bitrate, I would probably look at writing a camera when I have time. Never looked at attempting to mod the default one. Have found something odd though, did a few tests, and there should be perceptual zoom due to sensor cropping at 720p, but compared against an 8mp photo, there aint! So thats a bit wierd to me

According to you, is it possible to modify/create a camera app that implements a digital zoom or better algorithms for image sampling?
What kind of access is possible to gain to the application processor's peripherals with android os?
There are some realtime image scaling algorithms that could be implemented via gpu or, better, via dsp if the exynos integrates a dsp onboard (like the TI's omap do).
I would really love being able to do some slow-mo videos with my SGS2, any way to do so?
The camera simply isn't built for that kind of use. You could do it, if there were software, but the framerate would be atrocious.
Here's an app for playing back videos in slow motion...

Probably the best and only solution. The camera was only built for up to 30fps I believe. If you know how slow motion cameras work (very high frame rate), you should see how this is a problem .
I'm bringing this thread back to life to save cluttering the board up with yet another similar one. I've been looking for an app to do the same thing and have, like other searching, not found anything to suit.
The reason I'm still chasing it down is that I had the Samsung Jet before my SGSII and even given it's age and utter lack of power compared it had the feature to be able to record video at high speed so that when played back it would be very good quality slow motion (25% speed if my memory recalls correctly).
Now, if that phone could do it so long ago with little native power and a poor camera then surely the SGSII could do something like that at the very least, even if the max video size had to be dropped to 640x480 or similar to keep the framerate more locked in?
Want that too!
Can somebody pls answer this question.. Is 30fps hardware limitation?? Really??
I once had Samsung OmniaHD with 8Mpix camera, probably not much different from any other, and 320x240 resolution it was able to capture 120fps..
How can it be a limitation of hardware? Isn't it possible to write an app that would capture even 240fps at lower resolutions?

I'm searching for this since a year from now, I think the problem remains in the drivers and not in android SO, there is one or two android phones that support is, but I dont know how exactly, if I dont misstake samsung galaxy note 2 and one motorola has slowmotion, I belive that they build a driver to use de camera as fast as possible, on other devices I think that is not possible unless some can build such driver, and that probably will need to do in some native assembler code of each device cpu and irqs, unless the company release that driver
the functions of android to get frames from camera are very limited to useless stuff and pre-set formats and fps
I dont know whats about with android 3.1+ or 4, maybe thats SO has this functionality natively
get fast fps from a ccd camera is not a MP issue nor too much CPU requeriments nor related to amount of RAM
with a windows mobile 6.1 device such samsung omnia i900, that has a 625mhz CPU and a 5MP camera you can record 120fps in 320x240, the camera of this phone has ISO 800 (it doesn't mean 800fps, but means that it can get a very tiny little power signal from sensor in a very short amount of time) but android cameras discard this features and incorporates functions very limited and related to normal users

I don't think you understand the concept of cameras well. The hardware determines whether it is 30 or 60fps and not the software.
For slow motion, the highest a consumer (or affordable) camera does is 1080p at 60fps.
There are cameras like phantom hd that do well over 1k fps but they cost 100k

Not completely accurate.
For a consumer camera, the highest framerate at 1080p might be 60fps like you say, but some low cost consumer sensors can do high fps at lower rez. My $100 Canon Elph 100HS from 2011 will do 640x480 at 120fps or (I think) 320x240 at 240fps. I've used the 480p120 option and it came out very nice for sports use, especially for reviewing batting swings with players. The sensor tech for fairly high frame rate at decent (480p) rez is not limited to >$1000 cameras, leading me to believe it's probably more software related. I don't know enough about the sensor in the GSII though.
*Edit*
Apparently the Galaxy S II uses one of two identically spec'd (according to Anandtech) sensors from either Samsung or Sony. The Sony IMX105 specs are here. According to that page the sensor should be capable of 120fps at 1/8 sub sampling. I am not entirely sure what they mean by 1/8 sub sampling, but I would assume that it means using 1/8 of the effective pixel count or about 1M pixels. If all that is true, then the hardware should be capable of 640x480 at 120fps. Some assumptions there, though.
I just sold my transformer prime infinity...and coming from that, im disappointed with the screen. How could a lower resolution screen on the prime look sharper than the one on the nexus?
Well I was just looking around here and I don't have a Nexus 10. I got a Galaxy Note 10.1 and from my experience the picture matters a lot.
I mean there are a lot of wallpaper sites with ultra HD and optimized wallpapers for retina display, but the same resolution is not always the same sharpness. some are crappy cropped or zoomed.
Use quickpic to set your background picture. The stock gallery app sometimes crops the pictures false.
And pictures with a resolution below the maximum resolution will always look a bit crappy. that means that when you are using a fullHD picture, which was nice for transformer prime, it can look less sharp on a display with higher resolution like nexus 10
I too come from Prime and there is no contest, this screen is sharper than Prime by miles.
How stuff looks will depend on what you are seeing.
If you have set regular wallpaper, it will look all blurry thanks to resolution. Even so called HD wallpapers will look blurry on this. You need to go search for wallpapers for MacBook Pro retina and use those on this tablet using quickpic. None of the apps from Android market have good wallpapers that are having native resolution of this tablet.
Text is sharp and crisp on this.
Most arcade games are not optimised for this screen and look terrible or blurry. That is not screen's fault.
Desktop web pages look nice full and crisp. So only real issue of lack of sharpness comes into picture when the content is not ready for screen. That includes apps, images and games.
I also come from Prime.
I wouldn't say the Prime screen looks sharper than the Nexus 10. Reading text on the N10, for example, the resolution is really amazing, very nice on the Nexus 10.
The colors and brightness and blacks is a different story. The Prime had those 3 much nicer than the Nexus 10. I loved playing Marble Blast on the Prime, the graphics looked amazingly vivid. On the Nexus 10 they appear as meh.
Its the prime infinity. Drastic difference. What a shame. Gonna put the nex up 4sale.

It's mainly because a lot of apps and mobile sites and such aren't made for the resolution. It's made for a smaller resolution, so to make up for that, the apps, mobile sites, and whatever else are all upscaled to fit the 2560x1600 resolution. While upscaling allows you to view things bigger, it will also make everything else a slightly blurry. There are upscaling algorithms to make it look better, but basically it's impossible to make upscaled images look as good as a native 2560x1600 image.
A 720p 10" screen (Note 10.1) will show a 720p video the cleanest because the video outputs a ratio of exactly 1:1 pixels.
A 1080p 10" screen (TF prime) will show a 720p video a bit blurrier because the video outputs a ratio of 2.25:1 pixels.
A 1440p 10" screen (N10) will show a 720p video the blurriest because the video outputs a ratio of 4:1 pixels. (I know the N10 has a 1600p screen, it's just to make calculations slightly easier)
Now when using a 1080p video, a 720p screen will show no improvement because the screen can't output those extra pixels.
When using a 1080p screen, the screen will look sharper than that 720p screen because you have more information. Consider watching TV of a 10x10 resolution vs 1920x1080 resolution. The 1920x1080p resolution will look far better
Once again, the 1440p will look slightly blurry.
Now when you use a 1440p video, you can probably guess which screen will output that video the cleanest.
So basically, this high resolution thing is good mainly for texts as of right now since nothing is really optimized for a screen beyond 1080p.
Anyone who thinks its possible for a much lower resolution screen to be sharper is a fool. This screen is absolutely dazzling. Though content displayed is obviously going to have an affect.
And just to shove some numbers in your face:
N10 - 300.24 PPI (2560x1600 @ 10.055") 4,096,000 pixels (78% MORE)
Prime Infinity - 226.42 PPI (1920x1200 @ 10") 2,304,000 pixels
That's a huge difference.

A 1440p 10" screen (N10) will show a 720p video the blurriest because the video outputs a ratio of 4:1 pixels. (I know the N10 has a 1600p screen, it's just to make calculations slightly easier)
Now when using a 1080p video, a 720p screen will show no improvement because the screen can't output those extra pixels.
When using a 1080p screen, the screen will look sharper than that 720p screen because you have more information. Consider watching TV of a 10x10 resolution vs 1920x1080 resolution. The 1920x1080p resolution will look far better
Once again, the 1440p will look slightly blurry.
Now when you use a 1440p video, you can probably guess which screen will output that video the cleanest.
So basically, this high resolution thing is good mainly for texts as of right now since nothing is really optimized for a screen beyond 1080p.

I actually have to disagree with you a little bit here. 720p video should look just as good on the Nexus 10 as it does on the Note 10.1. 1280x800 times 2 is 2560x1600. Because of that each pixel of a 720p video will take up exactly 4 pixels on the Nexus 10; however those 4 pixels on the N10 are the same area that would be a single pixel on the Note 10.1. This is a clean ratio. On the TF700 you got to 1920x1200 which is 1.5 times 1280x800. This is not a whole ratio and means that pixels of a 720p video will take up between 1 and 4 pixels on the TF700 display (determined by a fancy algorithm for scaling images).
The Nexus 10 playing 1080p video should have about the same blurriness as the TF700 playing 720p video.

Anyone who thinks its possible for a much lower resolution screen to be sharper is a fool. This screen is absolutely dazzling. Though content displayed is obviously going to have an affect.
And just to shove some numbers in your face:
N10 - 300.24 PPI (2560x1600 @ 10.055") 4,096,000 pixels (78% MORE)
Prime Infinity - 226.42 PPI (1920x1200 @ 10") 2,304,000 pixels
That's a huge difference.

Did you have a prime to compare it to? Sorry, but text IS crisper on the prime. I see it with my 20/20 eyes.

Lol as a former owner of both (returned Prime C1 for 700 a C6 then returned that, and I started the thread in Prime forums for users who Asus lost our first mailed GPS dongles)- your fooling yourself or you got a N10 with a bad screen

You can most likely blame that on googles new font rendering in 4.2. They turned down the font hinting a lot. It would be nice if it was configureable like in Linux. It the same way on the galaxy nexus and nexus 7 in 4.2.

The problem with this screen is calibration and black levels.
Colors are extremely washed, red is a poor red, same with blue. This totally kills the screen. If you compare this with ipad screen, you will cry. Not because of viewing angles, not because of brightness, because of colours. Google was really smart when they decided not to calibrate their screens, same with nexus 4, while other OEMs take care of this thing deeply.
And black, despite numbers of the reviews, its quite poor, mostly because every single unit has light bleed (some with a hard mess, others this problem is smaller)
As a result, a top screen with such a poor implementation. This could be best screen in an tablet ever, and now it is a mediocre one, with many pixels, but nothing else. And it's a ****ing software issue, thats so sad.

Yep, meant the calibration thing, it's about software. Black thing is because a bad manufacturing process, probably because of low price tag., or crappy manufacturers.

Wow...that blows. Maybe we need a 4.1 ROM??
I saw light bleed as soon as I turned my N10, but that's not the reason I just called to return it -- it was the uneven brightness. The top 1/2 inch of the screen is noticeably darker than the rest of it -- not visible when watching a movie or playing games, but very distracting when surfing and reading books, especially in portrait mode.
Since I haven't seen anyone else complain about this issue, I'm hopeful the replacement will be better.
Yep, I completely agree with one of the previous posters, this is definetly a black level issue. I put the iPad with a Retina Display right against a Nexus 10 both playing the same 1080i MKV. The iPad clearly won.
I still like the Nexus 10 a lot and I find it very comfortable to use because of how thin it is and how light it is, but to improve the product I think Google missed it some here. They could lowered the resolution considerably (1920 x 1080 is more than fine), improved on black level, and used the same processor. The lower resolution would have allowed that processor to scream since it wouldn't have been as taxed to interpolate so many pixels.
I don't know if it is a software issue or not, but if it is I really hope Google releases a fix. If there was a way to adjust Gamma or Contrast it might help considerably.

There's no way on earth text (or other computer generated content like the UI and icons) will look better on a 147PPI display (Prime) vs. 224PPI (TF700) or 300PPI (N10). The reason is as 404 Error did a great job of explaining is that text is a 1:1 match pixel wise; the more pixels the sharper the image. Photos and videos display even the clearest content over multiple pixels so the advantage of a higher PPI becomes less pronounced. And the human eye (even yours) can't resolve sharpness over 229PPI beyond 15". So, your 20/20 eyes are decieving you. The N10 has less contrast and isn't as bright as older displays so that might be what you're reacting to.

Mine has this problem and so do at least a few others. See http://forum.xda-developers.com/showthread.php?t=2007676
I'm still debating if it annoys me enough to justify an exchange.
Is it possible to port this amazing game tuner app to our device?
How useful it is? according to my research...
Game Tuner is a truly useful piece of software? From Samsung? Color me surprised, too, but the company's new Game Tuner app is nothing short of incredibly handy for mobile gamers. As you may well know, playing visually-intensive games on your smartphone can demolish the battery fairly quickly. While most such games render at 1080p even on 2K displays like Samsung's, such resolutions can be big draws on both your remaining juice and your device's processor, causing throttling (and thus slowdowns) and excessive power drain. Samsung's new app lets you have a say in just how graphically hungry those games will be, allowing you to adjust maximum frame rate and resolution scaling.
For example, Hearthstone for Android on a Galaxy S6 edge+ renders at, near as I can tell, 1080p natively. With Samsung's Game Tuner app, you can turn that up to a full 1440p (aka 2K and probably not a great idea!), or all the way down to around 480p. The difference is very real. The frame rate can be adjusted from 15 to 60FPS.

i dont think we need this.our display is already on hd.the lowest best possible so no need for it.redmi 3 battery life is superb so i relly think we dont need this app.

Actually our device is running on 1080p which is FHD ... by this app we can adjust the quality of the game and adjust the framerate for more smoother experience ...

we have an hd screen and you are saying FHD ???how is that.games run on 720p not 1080p on our devices.so dont say things like that
FHD = 1080p
HD = 720p
The redmi 3/pro is a 720p screen resolution. I think the framerate adjustment might be helpful depending on games that arent necessary to have high end graphics but still dont run as well as they could

Hi,
1st off I love this phone. I am extremely pleased and have zero complaints so far. Buttery smooth too....
My Question is how is it possible that the screen resolution is adjustable? Does the display turn off pixels? Does it merge pixels? Please enlighten me..
Thanks,
Joel
I'm pretty sure it must be 'rooted' first to allow those changes.

Sorry even though u r pretty sure. This info is wrong. U DON'T need root. Just like samsung graxe ui. On LG V30 u go to display - screen resolution and switch between 720,1080 or qhd+.
But the OP never asked if changing resolution was possible. He most know that we can already change res in the setting. What he is asking is HOW does lowering resolution works.
Im not sure about this but from tv or any pc monitor u can upscale to max reolution of the monitor or downscale to a lower resolution. The pixel are still on but the screen is not push very hard.
Amoled are very power effecient and this has been discuss in the S8 forum for quite sometimes. After all the testing the xda members have been doing it seems that going from QHD down to 1080(full hd +). Doesnt save that much battery (around 5% better battery)
Actually I'm wondering because on a 1080p TV, when you feed it a 720p video, the TV stays 1080p. The video is just enlarged to fit the 1080p display. On the V30 I'm under the impression that the display will actually change. Kinda like having a 3 displays in 1...

U wont see a smaller screen. The screen will stretch out edge to edge but it will look very blurry if u do 720p. Not so much in 1080p mode. So u can say that the software upcales lower resolution. Just like riptide 2 which u can lower or max res in the setting of the game.
Wait, so the software downscales? You sure? Just Android or all apps too? I don't think so. How could software down scaling effect battery life?

The screen is cap at 60 hz. Let say u are playing a game ( this goes with the ui smoothness aswell). Since the screen is cap at 60hz means that the fps is up to 60fps max/cap At 1080p is you play a game that can reach 80fps(cause is not pushing QHD pixel) the cpu/gpu doesnt have to work has hard. So instead of doing 80fps it only have to do 60fps meaning that cpu/gpu doesnt have to work 100% since is able to maintain easily the frame per second require from the 60hz screen.
This is why the new RAZER phone with 120hz screen can do 120fps.
Now if u increase the screen to qhd (1440p+). The same game with higher resolution the frame rate will be much lower. Now. The game probably is reaching 55fps instead of 80fps max (is an example). The screen is 60hz (60fps). So the cpu/gpu is gonna be working 100%. Much harder cause is trying to reach 60fps but it cant. Which equals more power comsuption, hotter device and also cpu/gpu throlling cause of the heat.
