So...Seeing how this problem keeps happening...
Every few matches I am in the middle of the match, and my screen just goes full retard. It get's stuck, when i press on f10(menu) I still get all the sounds, but my screen is frozen. I have to quit through ctrl+alt+del, while it says the program is still responding. And since it happens in the middle of the match it's really bothersome to leave a teammate out of no where...
I don't know if anyone else has had this problem, but I hope I can get some help from you guys while I'll try some stuff myself.
