In-game VSync makes the game unplayable for me (so slow as if the screen were "sedated") and forcing vsync with third-party program won't fix the cav rubberbanding. I hope there's another way to fix this issue.
Edit: I think that it's just EU_7 lagging, because I just got rubberbanding on foot without ping changes, and the server has crashed like 5 times since yesterday.
Forcing Vsync with 3rd party program works just fine too.
