Just out of curiosity, the OpenGL plug-in exists in the AfterEffects>Plugins folder, right?
Aside from that, have you tried to roll back to an earlier supported driver version?
To be more precise, it's inside After Effects CS3\Support Files\Plug-ins\Extensions, at least in AE CS3.
Adolfo, thanks for the article. But I want to point out that the technical
support document mainly concerns people who are having problems and errors
with OpenGL. Like artifacts, no rendering etc, often accompanied with
explicit error messages. My problem is that After Effects refuses to
recognise which version of OpenGL I have. From the output sniffer_gpu gave
me, I can say for sure that it is detecting my graphics card (nVidia
8600GT), but no what version of OpenGL my card supports. I have the latest
drivers for my graphics card (Forceware v182.08.
Vivek: Can we rule out something? Is your card set to 24-bit color?
It is set to 32-bit colour.
Vivek, do you by any chance use customized 3D settings in your NVidia control panel? If so, please reset them to their defaults. In addition, consider downgrading your driver. Knowing NVidia, it's possible they changed around some crucial setting or messed up one feature while fixing another. if it's possible, please provide screenshots, a dump of your system info, DXDiag and/or Realtech VR OpenGL Extensions Viewer. You can send them to my mail (mylenium<|>at<|>mylenium<|>.<|>de), if you don't want to share them publicly here on this forum.
I'd just like to point out, that my problem has been solved, thanks to Mylenium. He suggested that I run a few diagnostic tests, and consider downgrading my graphics driver.
Upon running, OpenGL Extension Viewer, I found that several of the OpenGL functions were unavailable, and that it detected OpenGL version 3.0. This was when I was running Forceware v182.08. I then downgraded to v162 or v163, which only had OpenGL v2.1. After this, OpenGL Extension Viewer did not give errors, and sniffer_gpu detected my OpenGL version without any problem, following which I was able to enable OpenGL rendering in the Preview Preferences window.
My pleasure. ;-)
