what do you mean by glitches?
Saw blades can be pretty bad for performance right now for sure

Recently I've been playtesting on an older PC, and I notice this as well. At the moment the only fix seems to be trying to run it on a newer computer, or running it in a window at a lower resolution. The Windows shortcut for windowed mode is Alt+Enter. Right now it's slightly buggy, so you would have to adjust the windowed resolution manually (Esc -> Options -> Graphics.) - The slower PC I use has a 900p monitor, and I set the windowed resolution to 720p (1600x900 & 1280x720, respectively.) - I notice a more playable framerate when I set it up that way. - A performance update may be considered at some point in the future, but it's not on the shortlist with the November 25th update on the horizon, and the Twitch Mode update following in December. - Hopefully the resolution trick works a little for you, otherwise I don't know of many other performance tricks. Sorry about that :-(
