This doesn't happen with ZDoom, so I'm curious about why it happens and if it can be prevented somehow. Running the latest SVN build here.

What graphics card and CPU? I don't get any slowdown.
The problem is most likely caused by the skybox which uses a line_horizon special to extend the sky into infinity. To handle this some tricks are necessary that may stall older hardware.

I just figured out which option was causing the slowdown; anisotropic filtering (16x)
Disabling it allows outdoor areas to be played at full speed.

Try 4x or 8x. I never had problems with those on a GF 6800.
