Short time after launch game client FPS drops down almost to 0, sounds got laggy, even cursor. And then i have to reboot because all things just stoped and sound crazy.

I checked my GTX 680 with Furmark and GPU Z - its totally ok, 3d mark 11 and vantage have normal scores.

I checked my i7 processor with Intel Processor diagnostic tool - all tests ok.

I checked my RAM with standart windows test and its ok too.

I checked my SSD and its fine too.

Please tell me why my tough PC dying every time i launch your game and what do i need to do to play it.

PS. Befor the last patch i got only FPS drops from 60 (limited) to 20-30, wich is bad... but i can handle it.
