Lumakey shader slower than jit.lumakey with noaccel

    I'm working through some OpenGL stuff on this machine:
    2 X 2Ghz Mac Pro, 1 Gig RAM
    OS 10.4.8
    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.
    lumakey_CPU
    max v2;
    lumakey_GPU
    max v2;

      your gpu patches will not run faster than your machine's display refresh rate. my guess is that you're looking at a machine with a 75hz rate, yes?

      Sure it can, just disable vsync on the jit.window, and you'll get very high fps. But for all intents and purposes, what Josh said.
