Not knowing what kind of system's you own, but perhaps either your graphic card or CPU is out of date. Just a guess, as I've not seen anyone list their specs. Not that I have a stellar system, but I've got a 1.8 GHz and a GeForce 4 (latest drivers) and experience no lag at all in Druckkamern. It's very smooth. Seems like the added rainfall slows some people up, though.

Out of curiousity, do you that have lag trouble with Druckkamern also have trouble with Omaha Beach. That map in Allied Assault seemed to cause a lot of similar problems to people, though it ran fine for me.
