zbuffer fighting

[mrrolf]

Hey guys. I recently wanted to go back and play through Doom3 again. I'm getting some artifacts though. When monsters spawn the star on the ground is messed up. It looks like some zbuffer fighting or something. When I move it 'flashes'.. and for some reason the alpha isn't working. Has anyone else seen this artifact.. or know how to get rid of it.

Below is a screenshot.. note that it is much worse ingame while moving.
