I found another way to 'fix' it. I normally run the game with a 
resolution of 800x600. Changing to 1024x768 and then back again to 
800x600 results in normal game performance without restarting UT. But 
after some reloading performance decreases once again.

... which is because there are two mtrrs for the AGP memory. However, 
disabling AGP makes the frame rate dropping disappear. Well, at least 
it seems to be ~9 fps everytime I 'fly' to my testing place. If this is 
the root of all evil, does someone know how to fix it?
