monitors do increase the amount of frames they can display.Monitors don't increase the FPS, the amount of RAM, GPU and CPU do.
If you're wondering I game on a Samsung smart TV
it's a normal 60hz monitor but overclocked to 75. makes a big difference believe it or notWhat monitor do you have; I'm looking to get a new one and assuming that you said 60fps is unplayable I think your monitor has 90+Hz
but comes with this glitch where if it's between 60-75 i get alot of input delay. it needs to stay at a stable 60 or 75 for it to be playable
