well, this depends:
first: do you have a fast graphics card ?
geforce should be ok.
the example patch 07.texture/04.moveImages.pd is a good starting point.
if the spheres move smoothly, try optimizing your patch
if they don't, you might have no hw-acceleration.
if the XServer (i guess osX is Xserver-based...) eats 99% this is surely
try getting a good card with an appropriate driver.
if this patch is ok, you might want to set the refresh-rate of the
gemwin with a message like "frame 30" (which gives you 30 fps)
and of course be sure, that you update your movement accordingly:
a translation by 1 each second will naturally be more jerky than wee
translations of 0.02 each 50ms.
