Ok, I've gotten rid of most of the choppyness. Here's what I did:
I went to the
http://www.cusl2.com webpage, where I ran to updates on my BIOS. I got rid of that stupid PC probe software that was buggy as sin. I reinstalled quake, three times. I also realized that my PCI bus was not being recognized properly, so I reinstalled my CUSL2 hardware drivers.
I still have a little choppiness, but it's for the most part gone. If anyone else would like to speculate as to what's causing the last of this, please respond. There is nothing more annoying that having to wait for a computer to catch up....
Thanks,
Wilks
