Okay, I have no idea what's going on here, but here's a legit OpenGL demo spanning across both GPUs:

I suspect the Rage is running the demo on an OGL surface and it's just passing the half that Voodoo card needs to its framebuffer somehow. This ran really slow, not just in terms of FPS, but also the timing. I don't know if the interplay between the two video cards was causing it - this demo makes heavy use of colored alpha blending and renders internally at 32 bits, stuff neither of these two cards are particularly good at. It took a while, but it got through all three parts with no glitches other than the slowdown.

It's a neat game! I was just trying out the demo here but I like what I've seen so far. A friend bought this new back in the day & I remember having some fun playing through it at her place. Shame it's kind of been forgotten.

Hmm, how many PCI cards do I have here? Heh... ha ha... ahahMWAHAHAHAHAHA-

Well, this, since you asked:

^^ although this was the DX7 test. After I hit enter, it ran the same test in DX8 mode & that worked fine (spinning cube on the Voodoo, desktop on the Rage.) Both tests ran on the Rage with no BSODs.
I'll admit this setup hasn't been completely trouble free, but it's neat that it works as well as it does. (I've also found that deselecting "span the desktop onto this monitor" in the display properties hard locks the whole PC. Still trying to figure out why that happens.)
