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.

Have you tried setting the preview to Sreed, instead of OpenGL, and checked the camera movments?

Checking out that aspect may give a clue as to whether it's actually a fault of OpenGL or not.

I'm guessing your graphics card is newer than my FX5200, so I'd either say it's something to do with your current display drivers, or a bug somewhere else, because all cameras work at the same speed for me, unless I've got a huge number of things in the scene.

Done already: no joy, responsive main camera, sluggish hand and face cameras with a lonely untextured V4. Wireframe view, or textured figure and shaded view, no differences. Only workaround is using the fast preview mode. WAIT!!! The unresponsive cameras are the parented ones: head, hand and posing. Setting the main to point at something, it becames one of the worst among them! Seems as if the problem is thinning down to memory transfers between graphic card and CPU, and is related to the yerarchy of the figure...but WHY? And then, if I can work with a multimillion poly scene in Vue without hassle, then something is broken in Poser, no doubt... Thanks for your response, and happy holiday :)

Is it only with V4, or do those cameras have the same problem with other figures?

A couple minutes to test again... I'm seeing the same sluggishness with V3, with a bit more responsive hand camera but a really slow posing camera (it seems even slower than V4). Is it possible that the chain length from the camera up to the universe, as seen from the Yerarchy window, could lead to this? As I seen it, the longer it is the slower the preview is... If so, then the problem isn't in the graphic subsystem, time to go shopping for a more powerful machine (and 150$/gig RAM sticks :D). Thanks again :)
