Well I got 1440x900 listed as a resolution now for all games that support widescreen. I had to add a custom resolution into the nvidia driver control panel. But at least it makes things look right. I tried adding smaller resolutions like 1280x800 and 960x600 but they don't appear in game. I might have to try again later. But so far 1440x900 seems to be a very acceptable size/preformance spot for the 6800GT
but I'll have to try it again later when I can actually sit down and play titan quest for a while.
