Question about Intel XeSS and monitor resolution
Question about Intel XeSS and monitor resolution
Hello everyone. I was curious if XeSS is affected by your monitor's maximum resolution. For instance, with a 1080p screen, should I enable XeSS to get visuals closer to a higher resolution like 1440p? If the goal is to see sharper images without needing a display that supports that resolution, does it really matter? Perhaps I'm misinterpreting and XeSS compensates for this limitation. Thanks in advance.
Intel XeSS, nVidia DLSS and AMD FidelityFX Super Resolution are built to boost performance by rendering at a lower resolution and then upscaling it. This method allows achieving higher frame rates than the graphics card can handle at its native resolution. They're useful when your monitor has a higher resolution than your GPU.
What you might be considering are nVidia DSR or AMD VSR, which render frames at a higher resolution and then downscale them to match your monitor's native resolution using supersampling. This approach is applied when you have more graphics cards than monitors. These techniques are less effective than rotated-grid supersampling, resulting in modest quality gains, though nVidia's...
These technologies are built to enhance performance by rendering at a lower resolution initially and then increasing it to the original quality for smoother frames at higher frame rates. They're useful when your monitor can't handle the full resolution of the graphics card.
What you might be referring to are nVidia's DSR or AMD's VSR, which render frames beyond native resolution and then reduce them to match your display's size using supersampling techniques for better clarity. This approach is suitable when your GPU exceeds your monitor's capability. Intel doesn't currently offer a comparable solution.
Got it. Unless my monitor can handle the desired resolution, enabling XeSS isn't worth it. I tested XeSS Features in 3DMark and it stuck at 1440p by default. Running it in 1080p would have been better, but that would mean playing games at a lower resolution with XeSS to achieve my native 1080p. I think the performance gain would be minimal.
I wouldn't go ahead unless the system had a very weak Iris Xe IGP, because that would simply restrict everything to CPU limits. For instance, if Performance Mode was chosen, the game would run internally at 540p and then upscale to 1080p. According to the description, you'd get close to the quality of true 1080p while still performing almost as well as a real 540p, but unless you're using a weak IGP, it would just appear lower quality without significant speed gains.
