have battled now for a week to get the game to run! it would crash all the time, wouldn't run for more than 10 minutes, (black screen) had to reboot, I tried every different graphics setting, no luck? finally found the problem! disabled SLI setting in nvidia c/p now it's ok no more crashes, but this problem needs to be looked at!
if anyone has same GPU try this! if it works let me know.
