I have an ATI 1600Pro with 256 MB RAM, running in a P4 3Ghz and 2 gigs RAM, XP Pro fully patched. Using latest drivers from ATI (drivers only, no control panel, Ati Tray Tools for settings), I had no problem with Main Camera and GREAT slow-downs with every other cameras, not sure why; note that with P6 too I had this behaviour, though not as evident as in P7. Then I found a simple trick to get a FireGL 5200 via software hack only from my card, applied it, and... - SPEC ViewPerf (a free OpenGL benchmark): 300%, yep three hundred percent increase in OGL performance!!!!!! - Vue 6 Esprit: BIG, I mean B-I-I-I-I-G speed increase in scene management (an 1.8 billion polys scene was a joy to navigate), so the "upgrade" is properly working. - Poser 7: a small speed increase in working with main camera, and even worse slow-down with other cameras, Head camera included, no matter what I select in preview settings... Yes, I know that my card isn't properly a monster, there are much powerful ones around, not to mention the fact that the ATI Pro versions are almost equivalent to the Nvidia MX version of bigger cards (learned that two hours after having bought it, damn marketing bla-bla's.......), but the ViewPerf benchmark said I have a rather big increase in performance :blink: so there MUST be an increase in Poser 7 performance, right? I think there's something wrong with Poser's OpenGL implementation, and I'm going to fill a bug report hoping it will be quickly addressed. In the meantime, apart from working in wireframe mode when using other cameras than Main, are there simple tricks for preview settings? Thanks all.
