I know that this demo does not work on ati cards. When I wrote the demo the EXT_transform_feedback extension was not aviable yet and ati didn’t support the EXT_geomtry_shader extension. Maybe I replace the NV_transform_feedback with the EXT_transform_feedback someday, then it should work on ATI cards to.

btw, the demo doesn’t work on ati cards :/ (tested on a radeon hd 4850)

Very cool demo! I saw it and it inspired me in many ways. How hard would it be to make an OpenGL ES version? Any interest? I’ve got some ideas, please contact me, I’d like to discuss them with you!

Thats a redicioulos argument. Of course it still uses the CPU for driverstuff and drawcalls. Also the CPU has to wait until the Graphics card has finished the calculations. Why the cpu usage is 100% during this time is none of my concerne but of the driver developers.

You say it only uses the GPU, but it eats up 100% of CPU time, too…
