I am running T2X with GOG's Thief 2, no mods apart from what they put on installed. Each time I set the resolution (1920x1080) and graphic bit to 32 and start a game it immediately jumps into 16 but keeps the same resolution. Both Thief gold and Thief 2 do not do this and run fine and in 32 constantly. Anyone seen this and know how to fix it? I know very little about messing around with game files but if anyone knows if there is a way to force it not to change it would be appreciated.

Thanks that has got it working much better.
