I have a Radeon 9800 XT running on a dual xeon 2.4 with 2 gigs of ram and I dont notice any speed difference at all with OpenGL. This really bummed me out because I was hoping this openGL issue would help me with animating in poser so I could get the timings down better having something close to realtime playback but sadly its just about the same, still skips about the same number of frames. also rotating the model in the viewport isnt much faster.
