I have sometimes a freezing-pc-screen issue but it happens even when I'm not playing, I guess it may be rather connected with graphic card. It's funny because I can remain talking to people on teamspeak and listen to the music but I can't do anything to gain normal screen back. Restarting screen, unplugging it and stuff, it all ain't working. I just have to restart pc.
Again, I don't think it's WSE2 issue.
