America's Army - poor performance

[eqisow]

I have recently installed America's Army 2.5 on Dapper Testing; the game is jerky and impossible to play even at 800x600 and medium settings. The video drivers and such are undoubtedly set up right, seeing as World of Warcraft plays smoothly in Cedega at 1280x1024 and medium settings. My system specs are as follows:

Athlon XP 2400+
GeForce 4 Ti4200
1024 MB RAM

I also attached my xorg.conf below, just in case it'd be useful. Looking forward to hearing your suggestions.
