I have a GTX 1060 3GB video card. I get 60fps @1920x1080, but it still looks kind of bad to me. The ball seems sort of transparent and seems to stutter, but at least the game is playable. At 4k, with all the settings at their lowest, I get 20FPS and what looks like 1 frame per 2 seconds every time something major happens. What kind of video card do I need to actually play in 4k? Maybe something is wrong with my set up? I have the latest drivers installed, but I didn't try to tweak anything.
