What are you running, I was playing this on my steam deck and it looked really good with a solid 30 fps. I have a B580 in my main pc and have been bumping settings up from medium to a mix of medium high with ambient and specular RT on and I’m still getting 75fps without framegen or upscaling at 1080p. Xess and FG hits 120+. Not bad for a £250 card.
Are you playing from an SD card? I get a couple of little drops but no extended issues.
