Everything I have read and experienced on the topic has been a few % in either direction depending on the game's denoisers. Sometimes there is a performance uplift because multiple shader-based denoisers that consume CUDA-core resources are replaced by the RR model that utilizes tensor cores. Other times there is a penalty if the denoiser it replaces was already light-weight. Cyberpunk 2077 used to require DLSS SR to be active to use RR, so I can see there being a heavy performance penalty there. But they updated that IIRC? |
Haven't really tested this myself, so pulling data from net, but it seems that RTX 40 & 50 are those few %. Ampere gets hit much more.
