Hello! My issue is that I seem to be freezing approximately every two hours of sustained play during the Map loading screen (the one that describes the objectives and such.) The progress circle pauses, music stops, and it is impossible to ALT-TAB out, CTRL-ALT-DEL out, or anything. The freezing does not seem to be limited to any single map.
The only solution is a hard reset of the computer. Here is my rig:
NVIDIA GeForce GTX 560 Ti (updated drivers, also, no dice)
AMD-FX 6100 Six-core
4 GB RAM
Windows 7
It’s not a horrible issue, but rather annoying during sustained play.
