I'm using a Dell Precision 7540 with a Quadro RTX 3000 6GB and a 4K 100% DCI-P3 display. The panel looks great, but running games at native 4K is too demanding, even with DLSS set to Performance or Ultra Performance. I tried switching the display resolution to 1080p, but the image became extremely blurry. I was told to enable integer scaling in the NVIDIA Control Panel, but it still looks as though Windows or the display is applying additional blurry scaling. Has anyone solved this? I'm trying to improve performance without being stuck around 27 FPS. Windows build: 26200.9168.

Check the NVIDIA Control Panel under the resolution and scaling settings. Set “Perform scaling on” to “GPU” rather than the display, and make sure the desktop is still running at the panel’s native 4K resolution. A 1080p image scales evenly to 4K, so GPU integer scaling should produce relatively sharp pixels. Also test the setting with a game in exclusive fullscreen, since borderless or windowed modes can let Windows apply its own scaling.

I checked it, and scaling is already set to GPU. I’ll verify that the desktop remains at 4K and test exclusive fullscreen as well.
