My specs:Core2Duo E66008800GTS2GB RAMVista 32-bitI'm playing in 1280x1024, 2xAA, 8xAF (you probably won't notice the graphical difference from 16xAF, but the performance inpact isn't small). The rest on full details.I had the crasing problem, after about 20-25mins crash when saving, entering build, etc. Pretty regularly. I applied the hotfix from Microsoft, but no change at all.In that time I had set virtual memory: minimum 2048MB - maximum 2048MB.When I heared the error occurs because of "exhaust virtual address space", I set the size of pagagile as large as possible and that was 4095MB (message said it has to be lower than 4096). Of course you have to chose the strict size option and don't let the dumb Windows to control it.I use 2 HDD, C: for system and D: for games and not sure why, but I have virtual memory set on both of them. That means now: 4095-4095 on C: and 4095-4095 on D: (8GB in total Niezdecydowany )And now the result: I played yesterday for an hour without crash, and today for 2,5 hours and then.... crash Hey, you can't have everything, but this change definately distanced the crash(es) and I can finaly play the game for a reasonable amount of time.So in short: apply the 940105 hotfix and set the size of virtual memory as much as possible (maybe on 2 drives if you have more than one). At least it helped me.
