I have a Gefore 3, it's not the TI200, but they're close. I can run highest graphics settings across the board with this game. :)
MIP mapping enabled, 1280x1024 overlay on a 1024x1024 background,
my environmental mapping is on smooth, and you can enable bump mapping if it looks better on your machine. :)
<Observation>: The thing that will make this game chunk is the processor speed, not this video card. </Observation>
*note: observations are not based on any technical research, they are merely my opinion based solely on my half-assed amount of technical knowlage. =P
I hope this helps you. :)
