DLSS and FSR don't compliment each other. It would be significantly better for a game to use only DLSS than to use DLSS + FSR. FSR looks good at 4k only in comparison to no upscaling tech. DLSS looks and obviously runs better in performance mode (1080p) upscaled to 4k than FSR does at 4k Ultra Quality.
The reason I say that is because we know for a fact that FSR is worse than TAA Upscaling and DF has done their comparisons with DLSS 2.1 at 1080p vs TAA Upscaled to 4k from 1512p.
Ultra Quality in FSR upscales from 1662p.
It's not a perfect comparison since we will need to see real side by sides but I certainly wouldn't combine DLSS with FSR at FSR's current iteration.
