HypnotizedJelly: So I have been playing this game again since DLC came out. About 2 weeks flawless performance, now outta litterally nowhere my games started stuttering. I've no idea why, same settings as before when it ran great. Even tried lowering some but didnt work. Also tried a tip from a steam forum where they said that setting the frame limit to 59 works but for me it doesnt. Anyone got an idea to get my performance back? Thanks in advance.

EDIT:

I found out this stuttering specifically occurs when moving the mouse left and right in quick succesion. Continually turning the mouse to just the right or just the left doesnt stutter at all, while going "shaking" the mouse does. Doesnt matter what direction. This is really weird... I'm mind boggled...

madsci542: A bit old but figure I'd post anyway....I had terrible stuttering when moving and using the mouse...for instance, when I was strafing and panning the camera. Nothing worked....until I turned of GOG Galaxy overlay in the settings. Then worked as smooth as silk. Hope this helps someone!

GOG Galaxy folks: Please note and resolve. Thx!

Maddo534: Thanks madsci542. I had the same stuttering as described above. Turning off the GOG Overlay solved it.
