better" but that means dumping 64 boxes!
I'd make sure both the OSG and Performer apps are running
single-threaded/single process (PFMP_APPCULLDRAW).
You can set the environment variable OSG_THREADING to "SingleThreaded"
to handle the OSG app. I couldn't find an equivalent for Performer, so
you might have to edit the code and change/add the call to
pfMultiprocess(PFMP_APPCULLDRAW).
Also, I remember having issues with an Nvidia driver running multiple
contexts before. What happens on that machine if you just run two
copies of either program (or two copies of glxgears, for that matter).
You can try turning off Vsync (set the __GL_SYNC_TO_VBLANK environment
variable to 0), as I remember this helping to work around it.
I don't think getting a Quadro will help you with this problem (that's
just PNY trying to sell you more expensive cards). NVIDIA's Linux
support is way better than anyone else's, for both GeForce and Quadro.
you can also try fiddling with the cpu affinity of the OSG threads.
AFAIK in single threaded mode OSG would take CPU0 for rendering and move
the databasepager to CPU1.
See this:

Also grep the OSG code for "setProcessorAffinity".
