Re: nvidia - threaded optimization crashes

Apple has an explicit (AGL?) option to turn on threaded OpenGL.
It just states that the OpenGL driver starts a separate thread to 
execute all OpenGL commands. The downside is that with every glGet() it 
has to synchronise and this can make things worse rather than faster.
I tried it on a project of mine and things got quite a bit worse; 
ofcourse that tells things about my renderer but still, there's only so 
much time to devote to a rendering library.

Cra****ng is easier to do when multi-threading, that's for sure. ;-) 
Perhaps also it's a dangling pointer.
Debugging it... I don't know. Try other driver versions, that may tell 
whether it's perhaps nVidia or perhaps your own code...
