This depends on the game and the viewing distance + screen size for me. 30 fps in a tbs game like civilization is perfectly fine for me, but too slow for an rts like total war. 60 fps in total war works for me on the big screen living room tv, but I find it too slow on a desktop computer screen. I expect shooters with jumping and fast turns to benefit even more from faster fps than my rts games, but it’s been years since I played one.
