It might not help in fixing this, but I found that the framerate is much more
consistent if I load all cpu cores with something while playing ut2004.
Normally, the framerate counter is green, but flashes into yellow and purple,
which makes movements very choppy. When something is running in the background,
the framerate counter stays green, and all movements are smooth.

With the llvm compiler the game is unplayable either way.
