You will need to download and install the Graphics Rule Maker, then follow instructions of how to change the files in Config (can't supply link of those instructions as this site doesn't like the site of actual instructions for some reason) to make the game see a proper video card or chip.

I tried doing this and it didn't work for me. I got it to work in windowed mode, but it's annoying to not have the full screen, so I'm still looking for another solution.
