Junak_23: I would like to play on my current graphic settings.
MaxStrauss: I own the same graphic card, less RAM and an older processor - but there's no mouse lag.
Do you have the newest software for your mouse from the manufacturer?
What happens if you change the mouse sensivity in the options?
What happens if you take another mouse?
I've had my mouse since 2 month. It's Zowie FK1, best quality. I think that it is not fault of the mouse. I tried change my in game sensitivity and mouse DPI - didn't help. :(
Junak_23: My mouse moves with delay, it's very uncomfortable. Can you help me? [switch off overlay doesn't help]
Chaksis: Have you disabled GOG Overlay? It caused and causing some lag-issues.
I tried it before and then didn't help. I've just tried it again and now is better! :) But minimal lag is still there :( Is so much better and I can withstand that detail. :)
