I've been having a problem recently with several games (Unreal 2k4 mostly) where I'll go into the game, it'll be running at standard resolution (lets say 1024x768) and when I try to change it, the game either keeps the default resolution or crashes. Then, I end up in windows running that resolution (where I usually run 1600x1200), and I can't change it in windows without restarting anymore. I've tried reinstalling drivers (I'm running a 6800gt), and the problem still happens. I'd be suspicious if it was just a single game doing this, but it's several. Has anyone ever run across something similar? Thanks for any help you can provide.
