very good, theres another line online that disables Vsync which would get you over the critical FPS threshold which is i think around 180fps. so keeping that on should prevent it given your monitor isnt too fast.

I've had zero issues at 165fps. It's UE3, not a Gamemaker game.

This game is designed to be played at a capped 60fps, it is not intended for high frame rates. The engine cannot handle it. With high frame rates, certain abilities and game mechanics are broken and do not work as intended, resulting in game breaking unplayable experience. Not everything needs to be 200+fps. The best way to play this game is with the 60fps cap enabled.
