Highly depends on the type of game. For First person shooters, 120+ fps is a must. I skipped the more recent CoDs because I couldn’t get them to run at that target consistently enough on my PC without turning them into blurry DLSS smear.

Racing games, where motion is typically always going in one direction with only smooth direction changes, a lower framerate is fine (like 60 to 80), although the added smoothness from high framerate is obviously still nice.

Slower paced or turn based games I’m fine with going as low as 40 FPS, as long as it’s consistent without drops and frame pacing issues.
