I’ve never seen a list, but the website does list nVidia as the preferred vendor. According to the website, it requires Open GL 1.2.
According to OpenGL’s website, backwards compatibility is a requirement, so I would imagine it would work. OpenGL: Backward compatibility requirements ensure that existing applications do not become obsolete.
BTW, when I first ran Messiah, it ran kind of weird. I couldn’t read any of the active text boxes in my input fields. So, if I wanted to rename a bone to MyBone_ArmR, I could TYPE it, but I couldn’t read it until I exited the field.
Then I changed my OpenGL settings “Force Z-Buffer depth” setting to “Force 16 bit” and now it works fine. Dunno if that matters to anyone… but FWIW.
======================
From the PMG Website FAQ:
What are the system requirements?
Operating System: Windows XP (recommended; also runs on Windows 2000)
CPU: 1ghz or higher AMD or Intel
RAM: 512mb or higher
Hard Drive Space:100 megabytes
USB Port (for hardware dongle)
Graphics Card: NVidia is recommended, but ATI now works well too. The card must fully support OpenGL 1.2 at the bit depth and resolution you are working at. Some of the lower end cards (in the US$50 price range) only really support OpenGL at resolutions below 1024x768
