yeah it eventually crashes... disbale the buffer it decreased the crash rate....
dont set options too high cause they wont render, and dont set them too low cause either wont render. i run it under WIN7+2GB ram... which is a different condition, more favorable for the game, in your case must be harder and the crash rate should be higher and lower FPS also in my case after 30mins the performance started to decrease... dramatically, and suddenly became unplayable, i had to save and restart... and it became stupid so i decided to quit it.... but ITS ONE AMAZING GAME... totally worth it. -- INTEL 9xx SOLDIERS SANS FRONTIERS
