Nvidia Integer Scaling 1080p gaming on 4K monitor

Has anyone had success with using the new "integer scaling" introduced, I believe, in the RTX 30xx cards, to game at 1080p on a 4K monitor? Or perhaps game at 1440p on a 4k monitor?

Note: I believe that integer scaling needs to be enabled, first, in the settings

Before, when I tried using any resolution lower than 1080p on a native 1080p monitor, everything looked blurry

Is that still the case now?

I want to know if I should get a 1440p monitor...
Or use a lower resolution on a 4K (2160p) monitor (to improve FPS)

Thanks guys!

 

Integer scaling is supported and works well on Turing (GTX 16XX, RTX 2XXX) and higher GPUs. You need to use a resolution that is exactly half of what the monitor supports in order for it to function properly, so 720p on a 1440p monitor, 1080p on 4K, etc. Let's say you have a 27-inch 4K monitor, setting the in-game resolution to 1080p with integer scaling will cause it to look as if you are running on a 1080p display. So the image will be clear but scaled differently. If you tried to use 1440p on the 4K screen, the image will be small and surrounded by black bars on all sides.

 

Yeah, the interpolation will be annoying at anything that's not a 4:1 pixel ratio. You could also try in-game render resolution scale, those types of in-game configs usually leave the UI at native so things like fonts and other UI elements are scaled properly and look sharp but the 3D scene rendering can be scaled fractionally to lessen the load on GPU, usually it's the UI that's most noticeable anyway.

 

I haven't gotten around to trying it; not really a whole lot of incentive for me at the moment; although I'm more curious on the performance disparity on it vs FSR, but that'd require testing.

 

I think you're confusing integer scaling with DLSS. They're not the same thing. Integer scaling has no impact on performance.

 

Yeah, I probably am. Thanks for the clarification, haven't read too much into it.
