I posted earlier about whether my TNT based video card would work with Outcast. I did some digging on the Lucasarts website and came across this page...
http://support.lucasarts.com/trg/tgd.asp?id=2321&g=120&s=12)

It has a list of all the supported and tested chipsets (including some not listed on the box) as well as a lot of other good info about video cards.

Thought you all might like to know.
