The result is a renderer that does little to no scene management on the CPU, instead uses the GPU for visibility determination that is, in most cases, able to reduce the scene‚??s geometric complexity from over 400 million triangles under one million triangles providing an interactive experience on a Radeon HD5770 with around 200 frames per second.

Scroll to the bottom to see his performance figures.¬* It looks amazing, although they test it solely on AMD Radeon cards.

Whoa... interesting.

I rather miss the days where OpenGL and DX where actively competing. Seems now DX has taken over and a lot of the hype has died down. The whole market seems... dull. At least compared to a few short years ago.

Yeah, Microsoft has dumped a lot of money into killing OpenGL and pretty much forcing gamers into Windows. I myself wouldn't ever use Windows if pc games were primarily OpenGL rather than DX. It would be Linux all the way.

Yep, same here.
