openGL with geforce
Recently I started working with 3d layers in AE7. I am working on a PC with a core2duo 6600 and a geforce 7900gs. When I try to use the openGL preview, if opnGL is set to faster, I get a correct preview, but the animations run at a slower pace compared to the ram preview. If openGL is set to more accurate, I get a weird looking preview, pink\purple colors and no lights, details, alpha mattes or anything…
AE7 says that all features are fully supported on my GPU.
I have a second PC which is identical, except that instead of the 7900gs there is a quadro 1500 and it works fine with openGL previews.
Anyone knows about specific issues with the 7900gs or if there is anything to be done?
Many thanks in advance. -

make sure you have the latest drivers for the card.
however, if your previews are faster w/o opengl, don’t use opengl, use adaptive resoultion. there are actually only a few opengl accelerated effects in ae7. although there are several opengl accelerated features like blending modes and motion blur, most users prefer to disable opengl (it kind of a flakiness vs beneift scenario).
also, unless you use opengl for you final renders too (enable it in the render settings) your final render will actually look a little different than your preview due to the difference between how opengl calculate te render and for ae’s render engine calculates things.
