Hi,
  The X1600 is the same chip in the Intel-based Mac I use as a compile
box, and while it's ok, it's not setting any speed records here either.
Granted, I'm using it on a Mac and a new version of MacOS X, so there's
bound to be room for driver improvement, but it's certainly not at all
comparable to a GeForce 6800 for example. One question for you is what
resolution you're running at, and what representations you're using.
You also didn't say what host processor you've got, which while only
a small part of the performance story does indeed matter for some
representations, particularly when play trajectories.
