Medal of Honor Allied Assault on a 3dfx Voodoo2 SLI

Playing on a crowded game server 36 players.
You can tell the CPU and the cards are having some trouble keeping up.
Especially the CPU, a AMD XP3000+ at 2,11Ghz is having some trouble when there is too much to render.
I have installed WickedGL 2.99 after changing mohaa.exe to quake3.exe.
It gives the Voodoo2 an extra boost not having to render textures that are too detailed.
The PC has 512MB DDR 333mhz.
During recording I had no sound and the settings are as follow:
first on 800x600x16 all minimum but I quickly change to 640x480x16 bit (mode 3) just to get some extra fps here and there.
The amount of messages of kills, people joining and leaving is overwhelming at times.
The game runs as far as I from 19 to 120fps depending on the scene.
36 players is really hard on the cpu. I have similar frame drops with my Sapphire Radeon X1950Pro AGP card.
