Another thing I've noticed is if I press the "s" key to get the frame rate info, it flicks between 73 and 78 fps. I'm running 1280x1024@75Hz. I'm fairly sure that when it runs smoothly the fps stays almost constant.

Also, if I limit frame rate to 60 I get fps of between 39 and 41 and it's jerky as hell.

Any ideas?

Something isn't right.

You need to find out what is running in the background.

Of course, you also need to make sure your 4 in 1 drivers are installed and up to date.

This may or may not be way off base, but for all the people running fast Athlons on Fast KT266 or KT3 boards, how much power supply do you have? What are the reported CPU and Motherboard temperatures? Do your GF4's have fanes on them or just metal heatsinks?

If you upgraded, did you carry over the case and fans?

Or even better, if these are new systems, have you verified that they have enough cooling? Many manufacturers "overlook" decent cooling, especially with fast Athlon systems.
