Here's a quick mod I made that enables GPU acceleration and changes the framerate from 20fps to 60fps. Obviously invalid for runs but much more fun to speedrun imo (less downtime + smoother cursor movement). Also included is a version that only enables GPU acceleration without changing the framerate. This should help reduce input lag and stuttering on older machines.
