Same advice to you, Gryphon... lower some of your stats... my Computer is not as good as yours and it runs a nice framerate almost all the time... except, as I said, after a few maps... which is happily because of tribes 2, and not my computer

.
Also, Laurelin you should look out the Pentium 4 is starting to drop the prices of Pentium 3s... Not too shabby if you can get ahold of a sub-par P3... RAM will also help... I intend to upgrade my computer's ram sometime soon... fortunately ram chips are selling super-cheap right now.
The graphic options help *ALOT* they made sure the game could be useable on a lot of systems... But you will suffer only in how beautiful the game is.. As an avid player of the Original Nintendo, I believe game quality is better than graphic quality anyways... The game could look like Earthbound for all I care, as long as it has the same value of gaming in it as Earthbound did... Woooweee... Tribes 2 is a goldmine when it comes to game-play.
