I'm new to the Sam & Max games and just recently started playing them via Gametap. Originally, I was able to play in resolutions up to 1600x1200 in Vista. However, since I installed recent Nvidia drivers (158.18), my resolutions above 1024x768 are unavailable. These resolutions can still be set in Windows (every possible choice up through my monitor's max of 1920x1200), but the game itself caps at 1024x768. Where does S&M check for available resolutions? This seems to be the issue and I suspect it may be a Vista only issue. I've seen mention of a prefs.prop file, but I can't seem to find that in the Gametap version of the game.
Anyone have any ideas? I'd really like to play this in higher resolution if possible. Reverting back to the old NVidia driver really isn't an option as the newer one works so much better for other games.
