I have a 480hz monitor and play 90% of my time playing comp games with framerates exceeding my refresh rate
I also play maxed out single player games
On a seperate display
At 4k, max settings, path tracing, DLAA, Ray reconstruction and i get 25-30fps depending upon the title
I enjoy that visual fidelity more than the motion smoothness
I will get used to the framerate very quickly, especially with things like gsync
But a lower res and low settings just instantly puts me off a game
