Herky Jerky is when you move V3's arm and the display won't update until it's halfway down thru the motion, and you either overshoot where you want it to go, or have to grab the arm again and move it some more. It's like flying blind. Moving the slider/dials around is even worse. I like to keep those closed, because it takes so darn long for the display to update upon body part selection... Orbit the camera in a scene, even with textures turned off, results in skipping and lags. THAT'S herky-jerky. :-) On my system, Poser has this same problem, despite being unaffected by the video card (P4 can't use OpenGL acceleration) The memory fix might be the solution on that... The FX5x00 series is loathed by gamers, but will it work good for D|S? "Good" meaning -- end the herky jerky, smooth out the posing of V3 and other complex meshes (conforming clothes, scenes, etc) Local computer store has an nVidia 256meg AGP for $29...so tempted to scoop it up...
