There is no stuttering when I did what you said. My fps drops by 2 when I spin them all in circles on the spot.

Problem: Hopefully better explained.

If I am moving (forward/back) and I turn via mouse (right click) it stutters. If I am moving and I turn the camera view with the left mouse button (while moving with the A,D key), it stutters (not as much as if I was moving all the characters in a circle). If I close down keyclone and keep every one on follow, I get no stuttering when I turn via the mouse. I originally thought I was somehow creating too much info being sent to all the 'clones'.

The part that confuses me is. If I mute Keyclone, I still have the problem. It ONLY goes away when I close keyclone. Something on my system (or maybe I set Keyclone up wrong - although there isn't much to set up :P) doesn't like what is going on.

I have Maxfps set to 40, maxfpsbk is 15. The clones have their graphic options turned to the lowest possible.

Weird eh? :/

EDIT
Xar's old problem sounds like mine. Only it hasn't gone away T_T
