It looks to be a CG 'specific' game. AFAIK, no other graphic card can do CG 'yet' (and maybe not for a while) so it does look like a nVidia only game. Back to the bad old days......
Cg is not a proprietary language, and Nvidia cards donĀ“t run Cg. Cg is a high level programing language (Like C++) that compiles code into DirectX or OpenGl language and it can be run by any Dx8.x and higher compliant video card. How much the compiler is optimized to produce best results on Nvidia cards is another issue.
That demo is hardwired to run only on Nvidia cards, pretty much as G400 tech demo or Parhelia reef demo are hardwired to run on Matrox cards.
And the demo itself is interesting, but it runs like shit on a XP1800+/Ti 4400@300/630, and itĀ“s completely cpu bound (only 1 fps difference from 640x480x16 to 1024x768x32)
