fullscreen blackout

    hi,
    when I go full-screen, the projection blacks-out.
    The problem appears to be caused by using millions of colors on a beige G3. However, thousands of colors looks weak.
    I'm using jitter to create optical effects based on high color contrasts. The work is to be installed in a gallery, and I'm wanting to use the old G3 to run the software. I'm using os 9.1, and the processor is a 233mz with 384mb ram. The video processor, a ATI 64_3DUpro has 4mb ram.
    I'm wondering where the limitations of the image lie - if I upgrade the vram to 6mb, will that get me millions of colors? If I install another graphics card? If I run os 10.2.something? Are the limitations of the G3 such that it seems better to cut and run?
    best,
    Bruce

      Probably not. You'd be better off getting a newer graphics card if it's supported on your HW OS version. Would recommend 32 MB VRAM minimum.
      Another solution may be to reduce the monitor resolution when toggling fullscreen on (can use jit.displays for this).

      I'd personally upgrade to a G5, or if you can wait for Mach-O UB versions of your critical applications to a new intel based mac. You'll get probably more than 10x performance improvement over a G3 233. Not to mention you can then perform GPU based video processing with Jitter 1.5.
