PR loading map crash.

[SlLeNceR]

Hey guys to start off I have Intel quad core Q6200 2.3ghz and 9400gt and I play on everything high no AA and I get around 25 - 30 fps. When some maps are loading like at 60% done it crashes to desktop with no error message or anything and when I rejoin the game view distance lowers so I have to restart PR again so it can fix.
