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.
