Yes, that will likely remain that way, unless I can figure out a way to further optimize the optimized-smoke emitter that appears when 1 spam charge detonates near another. (or if you're on low detail settings)
I've never gotten choppiness from spammer smoke though, unless the game was already plugged up by something (such as when I throw 64 bots into Albatross with Projectors turned on, but even then I don't drop below 10 fps)
Just tested with those settings you mentioned,,,indeed with 64 bots and projectors on, it newer drops below 10fps:P
BUT...i tried once again proximity spammer and when running through smoke it dips down to 30 but as soon as go past the smoke the framerate returns to normal. Which GTS you got? the new G92?(i am asking this because that might be my card is struggling when there are lot of smoke:) )
One thing you shoud know is that on my 8800GT DM-albatross is not stuttering with gunreal mod,,,but only with plain ut2004..strange...i am beginning to thing that is somehow related to weapons and dynamic lightning....
Some CTF-maps are stuttering...but then again a wery few with GUnreal mod on...
