The 3D Analyse v2.36b gave UT3 & R6LV2 a very nice framerate boost with PS2.0 skip and low precision PS. Even though I own a OCLed GF7 SLI this program is now standard routine before starting these games because of the obvious advantages.
Big kudos for the developer of this program; yes I still own and use a 3Dfx.
Feature req: a PS3 skip toggle :)
