UT2004 demo will give you the same fps as UT2003 I bet. Very high, compared to many games out there. Yes, the full version may be different, but the demo still looks good. I haven't had much gaming time this week, and I have just been playing that demo at 1024x768 max with 2X/8X for now, but the average fps is near 100 on a R9800 Pro.
I'd drop the max settings if I were averaging 30fps and dropping to 20fps. Everyones different, but I hate seeing ANY hesitation and do not find sub 30 fps enjoyable at all. I'd rather lose a little details and average 40-50fps, minimizing the chances of the lows dropping into the 20's. Just MO
