I’ve had no issues with it so far. Optimizing took a while, but the load screens are no longer than say Crysis. Haven’t had any crash or sound issues either. Performance it could be better, but I noticed that vsync goes to 30fps instead of 60fps which makes it a little laggy. Other than that working great.
PS. Working great on a 64-bit ARCH! Installation with the Nvidia Beta drivers running at 2560×1080 on a GTX 670. Now I should my own drink
