Have you tried DLAA? Supposedly that one is the best for image quality.
I've only tried DLSS in one game so far and that was A Plague's Tale Requiem. The implementation was very good and I couldn't detect any image quality problems. This was with DLSS set to quality.
I tried DLAA in one game and wasn’t a fan. Made Fallout 4 blurry. F4 does require TAA due to severe shimmering on foliage. The game engine doesn’t support MSAA. FidelityFX + NV game filter do make TAA look quite good though.
But there is one new exclusive Nvidia feature that I love called SSRTGI (screen space ray traced global illumination).
Nvidia isn’t advertising this feature for some reason. They don’t even say when a game becomes supported. Enabling this on older games like Fallout 4 provide an incredible
visual boost.
It really does look this good! I don’t use DLDSR though. Enabling SSRTGI increases power consumption considerably though.
Some games I play like Risk of Rain 2 and Kerbal Space Program didn’t have the option to do SSRTGI until a recent driver release. It doesn’t work well in KSP yet, but I had no SSRTGI option for that game until very recently.
If I was NV I would be showing off this feature for the 4080 and 4090 release since SSRTGI can become quite performance intensive if doing higher quality; and AMD has no answer to SSRTGI.
