So...we've been dumb. To recap, we get the cards running with QE/CI but Cinebench gives us 6fps for OpenGL test. We've been trying different hacks, different configs....and the one thing we didn't try...was a different testing program. I was curious how my Power Mac G5 would work, so I went looking for a compatible program. I found GLView - OpenGL Extensions Viewer at kexts.com It tests OpenGL versions 1.1-3.3 I noticed that my G5's card doesn't do 3.0 and above. I then remembered that a friend I'd talked to about this suggested that a 2011 program might not be able to test a 2004 (or whatever) tech card. It's a Universal program so it'd run on Power PC's and Intel macs. One file transfer later, and I'm seeing frame rates above 300 for OpenGL versions below 3.0 and nothing for above. http://www.kexts.com/view/1034-glview.html (hopefully someone who's more familiar with this kind of stuff can explore/explain the program more).
