ah... j3d then.
well if it runs jerky it doesnt have to depend on a low framerate. i remember that i checked a j3d benchmark wich runs really jerky (guessed 30fps)... infact it was running with 650 fps :>
there is a benchmarking demo... wait... i search it...
ah k "demo\java3d\FPSCounter" there it is
start it via command line and _not_ inside your browser (java FPSCounterDemo).
u can turn vsync off via driver settings. opengl->always off (or summin simmilar). i dont know if there is a way to turn it on/off from within j3d.
