I'm working through some OpenGL stuff on this machine:
2 X 2Ghz Mac Pro, 1 Gig RAM
NVIDIA GeForce 7300 GT, 256 VRAM
When I load bball.mov and blading.mov into the patches below, I get around 75fps for the GPU version and around double that for the CPU version with noaccel turned on. Apparently upgrading to 10.4.9 improves OpenGL performance on this machine-- as it's a borrowed computer I'm holding off if it's not going to make a difference.
