Might be an unpopular opinion but after around two hours of gameplay I’m perfectly happy with the performance on my 3060Ti. On medium-high settings it can easily maintain 60fps on 1440p. That is with DLSS of course and ray tracing turned down to minimum.
The original Super Mario Bros. and SMB 3. The first console I got to play as a child was the NES at my grandparents’ house. Every couple of years I get a nostalgic craving and it’s usually those two games I return to. Also, there are many great rom hacks available if getting bored of the originals.
