Running FSR 4 on RDNA2 Graphics Cards Can Improve Image Quality, but with up to a 10–20% Performance Penalty

[Peter_Brosdahl]

Recent testing has shown that it is possible to run AMD's latest upscaling technology on older RDNA2 graphics cards, but there's a catch.

Cool next version is Redstone with path tracing

Hopefully it should come to steam deck & base PS5

That is interesting. The problem is AMD drivers have such a fine wine effect over time... meaning newer drivers on older cards are highly beneficial to performance. I wonder how much performance was lost JUST by going to the older driver versions.... THEN how much additional was lost with the new FSR tech.

AMD really should just make it work with older cards... but nobody would understand and just bemoan.. "but on my 580 it's slower with FSR4!! WHAAAA!!!"

I usually agree but Ironically with this they have to use a two-year-old driver to get it to work though.

Agreed, I just wonder what the performance lost is attributed to older drivers as opposed to FS4... though that might just be picking nits.

Yep, that would be a bit more challenging to identify. Doable but time consuming.
