i have 2 computers in my house

piii 800 256mb ram gf2pro
p233mmx 64mb ram 12mb voodoo2

ok on the p233mmx on stalingrad on 640x480x16 and everything on lowest details except view model on full, the game was surprisingly playable. me and my little brother played DM for hrs, of course i wasted him. ahem anyway ...yeah

does anyone have any ideas on how to increase frame rates?
if theres a way to disable the smoke puffs it would probably increase the fps a lot.
