nVidia 8800 (G80) and OpenGL 2.1 issue

Hello,

I've replaced my old ATI X1950XT with a brand new 8800 Ultra in my Hackintosh today. I'm using the EFI strings for 8800 GTX (previously posted on this forum) and everything works fine (resolution change, hardware accelerated CI, QE).

I ran OpenGL Extension Viewer and I noticed that the OpenGL 2.1 display is not correct (the fractal animation on the surface of the cube is not rendered correctly, screenshot attached). This causes some glitches with Doom 3 I think.

Does someone encountered the same problem and knows how to solve it ?

My configuration: Leopard 10.5.2 (all updates done) with PC EFI 8, Gigabyte GA-X35-DS4, MSI 8800 Ultra OC.

Thanks!
