I find anyone that can use a 4000 series card extremely lucky. I can't use anything over a 1070. There is a night and day difference between my 1070 and 4080. The 4080 clearly is using some technique(s) with pixels to smooth them. I'm almost 99% sure its some form of temporal dithering. Even switching between the iGPU on the AMD chip and the 4080, I can tell a big difference in the pixels.
I will be stuck on my 1070 forever at this point. Unreal engine 5 can struggle on it if not optimized well. I don't think I'm holding even 60fps on Borderlands 4 currently on 1080p.
