UT issue

[Dewsick]

Recently just got a new PC and I've been messing around with some ATI and UT settings and I'll just give the low down.
Specs are:
Windows 7 Ultimate, SP1 
AMD FX-6300 Six-Core Processor (at 3500 MHz)
AMD Radeon HD 6670
8GB Corsair Vengeance
500GB 7200RPM HDD

I run UT at 77 frame rate limit and 75 refresh rate on OpenGL. It is smooth but mostly when I dodge or strafe it judders just a little bit. It's not what you call 'perfectly smooth', in some cases which people have managed to achieve.
It's a little irritating but it's a hell of a lot better than what I'm used to lol. Just want to know if it's some ATI settings (which I goofed around with yesterday and got it running a little smoother) or whether it's some UT settings.
Help would be appreciated, thanks

I had a problem similiar to yours and all i have done was to change do D3D8 driver. Give it a try.

Swapinterval=1 or 2 did help me more than the 0 value in regard on the game smoothness
