Thanks. I'll try that.Well, game for sure has resource management problems like memory leaks. That will be fixed, problem is to find it. Nobody can say exact date, that is like drawing Mona Liza - it will be done somewhen.
For me 99% is resolved by complete reload of the game once a hour or so. Then it works full ultras ok. And don't press F10 for screenshots.
Did you disable / delete the cache in the launcher?
I've seeing some posts on reddit about disabling the "Shader Cache" in nvidia control panel.
