Your post was a little lacking in detail but I think I understand your complaint. Either you're experiencing the dreaded video stutter where the game freezes for a few seconds periodically or you're having network issues where planes warp around like crazy for a few seconds periodically.
If planes are warping and/or you're getting periodic disconnects try to run ping in the background while you play. If you start having trouble alt-tab out and see if a packet dropped. Skuzzy posted the IP of the server on the sticky connection thread. To keep ping running go to Start->Run and type in 'ping -t ', where is the addr skuzzy posted. You'll see packet loss show up in that ping window if you're experiencing it.
If the game is locking up there are two approaches I know of to deal with the stutter. There was a stutter a few months ago caused by sound cards that required an excessive amount of CPU cycles, as they functioned in a way similar to winmodems. Many people alieviated themselves of this by picking up a PCI soundcard and disabling their on-board one in the BIOS.
Since the last patch I too have been having a bit of trouble with the stutter, and I found that my problems were apparently tied into windows services. Windows doesn't like to play nice (bad pun for *nix geeks) with cpu time, and services runs periodically every few minutes. My stutter was reduced from a near dishabilitating stop to a pesky momentary freeze when I went through and disabled all windows trash I didn't need in services. I think this menu is under Control Panel->Performance and Maintenance, but I dont remember for sure off the top of my head.
Anyway I hope this helps you and the countless other people suffering from the stutters.
