There's some confusion here. First of all, the resolution it runs at is fairly unrelated to the amount of texture memory you have. With more texture memory you get higher resolution color maps, bump maps, and specular maps. To get the highest resolution versions of all of that, you need a 512 meg card. That doesn't mean the game looks bad on a 256, just that you're not getting the highest resolution of everything. The game looks awesome on a 256 meg card.

Now, doing all of those maps means we are using a lot of pixel shaders. That is going to mean your performance is going to be directly related to how fast your card can process pixel shaders. As you know, as you increase resolution, the number of pixels increases exponentially, so that's why people running the dx9 renderer see a non-linear framerate falloff. Note that this has nothing to do with texture memory, and everything to do with pixel shader processing.
