Hello, I've had issues recently with my game freezing vs certain players in Ra2 QM's. I have to close the game via task manager. I beat one guy, game didn't freeze, then next match faced the same opponent where the game was laggy and screen froze. It happened right as I sold MCV. Is this cheating or something wrong with the game on my end? Seems to be cheating as it's only happened with 2 specific players. Any advice would be appreciated, thanks.
