Since the new update I have come across a HUGE bug that is impossible not to see It is ther fact that I can't play any online games while this is showing up. Happens while playing and spectating will submit more info on request
Interesting... There was other AMD APU users who reported increased loading time in new version. Just to make sure it's not related to that please try go to Windows settings and set page file / virtual memory size to 12GB: http://windows.microsoft.com/en-us/windows/change-virtual-memory-size#1TC=windows-7 Also if you're running via Steam it's worth to try non-Steam version.
Running from uber launcher is hit and miss, because I bought the game from steam but that is a different problem Not any better unfortunatly
