Really bad framerates with Unreal Tournament 2004..

[Circuitbreaker8]

First off, here is a quick run down of my system

Intel P4 2.6C @ 3.26ghz ( cooler master hyper 6 43* idle...its hot as balls in my room )
Abit AI7 with latest bios
1GB dual Channel (4x256 nitro/adata) @ 250mhz 2.5-4-3-7
Sapphire 9800 pro 128mb@ 440/370 ( vga silencer+AS5 ) with catalyst 4.2's ( tried 4.4,4.5,4.7...all suck on my system )
Audigy 2 ZS with all the patches/updates
Windows Xp pro

Anyways, I run UT2k4 @ 1280x1024 full details with 4xAA/8xAF. It runs very smooth until one or two characters pop up on screen, the the frame rates drop in the mid 20's! If there are a lot it drops to like 15-20 then shoots back up to 60 when i turn around. Now..I think its because I have vsync on b/c my moniter only supports [email protected] do you guys think?

What gametype? If it's Onslaught then that's normal. You're going to have to turn off AA and AF, your card can't handle it.

Im talking about normal CTF and DM! Onslaught is actually pretty smooth

Try turning off VSync?

Yeah, it does run a lot smoother without vsync....what exactly does vsync do besides prevent tearing? My moniter only supports 60hz @ 1280x1024....so I guess I need a new one.
