Yes go to your My Documents/My Games/Gas Powered Games/Demigod   folder and open up the file called Game.prefs in notepad and then use the search function to find 'primary_adapter' this will be your resolution setting.  Go ahead and just change that to what you want and hopefully it will work.

If not look a page or two back and find a post I created about the Direct3D problem, there is a link in there to a fresh Game.prefs file.  You will still have to edit the settings but it should help prevent something else from interfering.

I don't have a prefs file, but I do have a log file. The end of the log shows:

using an Acer Aspire 5610-4608 with Intel GM 950 for video. Latest directx/video drivers installed. Hmm.

GMA950 cannot run the game. GMA965 and above can *technically* do Shader Model 3, but is so weak that it's not really worth trying.
