I have this problem running XWA on XP (Nvidia). Everything will be fine, I'll be in mid-mission and the screen will freeze while the game continues in the background (i.e. I can hear the mission continue, but the screen is still frozen). Then when I try to reboot the game, I get to the hangar and all of the ships are very polygonal, very simple graphics. I learned that my config.cfg file has been changed (how the hell does this happen?) to:
so I change the line back to:
and the game goes back to advanced graphics where it is using Nvidia. But the game will freeze again during missions (sometimes I can make it through one without the screen freezing) and I have to change my config file again.
Anyone know how to change this cycle? Apologies if another thread addresses this, I couldn't find this precise topic elsewhere.
