Render Resolution Scaler (DLSS / FSR / XeSS)

Enter a native resolution and a scale factor and you get the actual render resolution your GPU draws before upscaling. Reverse it to find the scale factor from a target render resolution.

How to use
  1. Pick your native (output) resolution or type a custom one.
  2. Enter a scale percentage, or switch to a DLSS/FSR/XeSS quality preset.
  3. Toggle reverse mode to enter a render resolution and read back the scale factor.

Common questions

What scale factor does DLSS Quality use?

DLSS Quality renders at 67% of each dimension, so a 4K target is drawn internally at 2560x1440 and then upscaled.

Does a lower scale always mean more FPS?

Usually yes, because fewer pixels are rendered each frame, but the upscaling pass and CPU work set a ceiling on the gain.
