I know this is a stupid question but I have to ask it
Do I have to change my PC's resolution to 4K as well as changing the resolution of the game I'm playing or do game settings override the PC's resolution? ie, will changing game settings make it 4K or downscaled to native? I use a 4K TV but have my PC in 1080 for various reasons. I'm testing Overwatch and I'm surprised my 970 is handling 4K at 60fps.
right click on desktop > nvidia control panel
there you set up desktop resolution
ingame graphics settings > there you set up the game display resolution
if your desktop is 1080p and overwatch 4k your screen should flicker when you launch the game which is normal

if you can't tell the difference, then you are a pleb and have no need for 4k anyway.
>>55009415
So without doing this, it was just downsampled to 1080 before.

I genuinely don't notice a damn difference
>>55009376
if the screen is 4k and the games settings say 4k then the GPU is rendering and outputting video at 1080p, the TV has an internal upscaler that stretches the 1080p image up to 4k
if the screen is 1080p and you had the game set to 4k then usually the screen outputs a "out of signal range" error or something along those lines rather than downscaling
Downsampling on the other hand (or downscaling if you will) is when it doesn't output the error and scales down the image resulting in a superb anti-aliasing solution
NVIDA calls the feature DSR (Dynamic Super resolution)
AMD calls it VSR (Virtual Super Resolution)
before this people called it SSAA or just Downsampling

I get that, I just needed clarity on whether the game was restricted by my PC's resolution outside of the game, so if I raise Overwatch to 4K (with my 4K TV) it will actually go to 4K, and not be bound to a 1080p display because that's what the PC desktop resolution is.

If Overwatch is in fullscreen mode then the screen will go back when switching from your 1080p desktop to the 4k game
If the game is windowed at 4k on a 1080p desktop then the other 3/4th of the Overwatch game window will just hang off the screen in unviewable space

>go back
go black*
I am just awful today, it'll switch to 4k then switch back to 1080p when you close the game automatically

Thanks for the help. It was a stupid question after all.

>resulting in a superb anti-aliasing solution
this is actually a very poor and resource-intensive way of doing anti-aliasing.
MSAA uses shared luminance to reduce the amount of work by ~3x, and modern anti-aliasing (FXAA, MLAA) uses a shader which is ~10x faster and does not consume additional memory like SSAA.

superb in its effect not in its cost
honestly before the current gen any ole mid to high range GPU was kicking the shit out of the PS3 and 360 so if you could run a game you could still run it fine with SSAA.
If your card is a 4k card and you only have a 1080p or 1440p monitor then you could get away with it, if you have a 4k monitor and a 4k card you probably wont be using any AA anyway.
