Ok thanks again for having a look. I did make the map with older machines in mind, which is why I'm surprised you're having issues. Back when I had an older PC, when the game was popular, I didn't have a problem playing maps that were way more detailed high poly than this one.
I tried turning off dynamic light in the UT menu and honestly saw no difference. Please don't think I'm arguing, as I value opinions. But if you don't mind, tell me which lights you believe are classified as dynamic. The only I can think of is maybe the coronas on the torches.
I'd also like to know how it runs on other's computers so I don't go changing a bunch of stuff unnecessarily.
EDIT - K, just went and tried again. I turned texture detail to medium and dynamic lighting off, along with decals, and still noticed no difference. The coronas also stay on, which tells me they aren't dynamic light. The only light I could think that might slow down a machine is the one (1) with the torchwaver effect on the pedestal on the lower level, but one light with that effect shouldn't have such an impact. If you care to, list your pc and video card specs and how you have your video options in the game. If you have an older Voodoo card I would think it would run even better than mine. Again, not arguing, just trying to figure out the issue is all and if others are having it as well.
