I've actually been noticing odd frame rate issues with my 2 clones and was going to ask you about it, Key.

I have a Dual Processor AMD system with a single geForce 8600 GT video card.

This machine is my clone machine and is running 2 accounts. I split the screen horizontally, so that the top half is Clone A and bottom Half is Clone B. Both clones have the exact same screen size. I only have a 19" display running at 1280 x 1024. So I split the screen to 2 identical 1280 x 512 screens. (Actually a little less due to the task bar, but that's not important) Now I set each clone to run off one specific processor. Clone A on CPU 0 and Clone B on CPU 1. I always start with launching Clone A and then launching Clone B.

What I notice is that the top screen, the first client I launch, has a much chopper frame rate then the second clone, the bottom half of the screen. now so far this hasn't been a problem, but I figure in the future it might. Is this typical behavior?
