However, this doesn't seem enough. There must be some other test
that Quartz Composer is using, that produces this warning, for
instancde on a machine with nVidia GeForce4 MX w/ 64 MB VRAM.
Unsupported Configuration -- Patches in bulleted categories benefit
from hardware accelleration when the video card supports vertex and
fragment shaders. Your card doesn't have this support, so you may
want to avoid using patches in these categories.
Any hints on how to detect this, so I'll know whether to throttle
back some of our Core Image / Quartz Composer effects?
You basically need to detect if Core Image is running in HW or SW.
You can create a dummy composition with an OpenGL info patch and read
its "Core Image Accelerated" output
