This has been happening to me for quite a while. I decided to get a new PC.
So, now it's completely new, with a complete new install of EVERYTHING. It still crashes saying run out of virtual memory. World of tanks on the other hand runs on high graphics with no problem and gets 120+ frames per second. It CAN'T be the Pc. MUST be the game. COME ON WARGAMING. I NEVER see any comments on this subject from yourselves, and it's appearing all over the forum like a rash.
