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 

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?

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 

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.
