Hello. When I turn on anti-aliasing, after a short time (1-5 minutes), this error appears. If I delete or edit .cfg in my documents, the error disappears. By editing I mean I turn off MSAA. After this the error disappears. This is server independent. I tried:

Complete reinstallation of dayz
Checking the cache
Transfer folder from Exp documents
Antivirus scan
There might be something else, but I don’t remember what it was.
