Absolution troubleshooting - jerky movement?

EDIT: Nevermind... I figured out why the game was being jerky; it wasn't the game itself, but rather, it didn't like a new setting I made for my Omega Driver.

Though for future reference it better be said that jerky or slow gameplay won't be something "wrong with the wad", unless it's huge or hyper detailed, and even then that isnt something that can be "fixed", except by having more powerful computers
