It can crash with every map...
But it has to be ingame! Or at mapchange...
I got a "Radeon HD7870" and got for paintball 4x multisampling enabled...
1000fps on small maps, 600-1000fps on medium maps and 350-1000fps in worst case maps!
Build 38 worked pretty good... WITH SUPERSAMPLING 8x!
I always play with motionblur @ 0.768...
It crashed now again so... yea...
And i not always get a temp-ban! Its just if im crashing several times!
