pbuffers with nvidia?

I need to do frame-synched stereo (~50 Hz) on a Linux box with nvidia hardware. Unfortunately they don't support quad-buffering so I thought about using pbuffers and multithreading to always be able to provide the 3D display with the right image. Can anyone give me some pointers on that?

I have never used pbuffers but they are supported. With the latest drivers came some headers that was placed in /usr/share/doc/NVIDIA_GLX-1.0/include/GL/ for me. Look in the glx.h and glxtokens.h files for the pbuffers prototypes.

I have no experience with stereo views but I suspect that the pbuffer solution is very slow. It seems like you need to do it with some other method. If you are stuck can you post a more detailed description of the problem.
