Now as to what i'm referring to regarding the game STalker i read on other gamer forms that this game had issues when running on pc's using ATI graphic card especially the x1000 series. It just freezes up after a few mins., of game play. Hard re-boot then needs to be done to get back to desktop screen. AT one point i was able to ctrl+alt+delete and got an error message saying 0xc000012d application failed to initilize, and found out it's virtual memory involved i know this game requires some serious power but i do pass minimum specs, however i have noticed my card is heating up as well but i used ati tool and it shows normal temps so i have no clue what's the cause of these crashes.
Hope this info helps if not let me know what else you need to know.
