What are you trying to speed up?
OpenGL is not very friendly to multiple CPUs. The driver will serialize the two processes no matter what so the gain will be minimal if any.
The latest DirectShow versions of GEM will use multiple CPUs for decompressing video and grabbing frames from a camera. The pix_ objects do not use multiple CPUs.
On the 'Unix' based OSes (OSX and Linux) the pix_share_read/write objects allow passing video frames between Pd/GEM processes. Windows does not have a similar enough shared memory system to make it work like the other two OSes.

Hi, to get some benefit out of my dual core, I have tried to adapt one of my GEM patches to run on two pd instances, connected with netsend/receive. Well, it worked somehow but only with two gemwins... Is it possible to get the whole thing into one gemwin on winXP ??
thanks, Rainer
