My game stutters like hell on 1.27 on 1.61 it runs fine I’m using low graphics and all anyone know a fix?

You are probably reaching FPS above 150. When that happens on 1.27 the game bugs out and you get stutters. To avoid that you shall install RivaTuner Statistics Server.

Rivatuner doesn’t work for me for some reason
