-In general, however, the driver is rather slow because all vertex
-transformation is being done by an interpreter running on the PPU.
-Programs with many vertices or complex vertex shaders will run especially
-slow.
-This will be addressed in the future.
+Performance has recently improved with the addition of PPC code generation
+for vertex shaders, but the code quality isn't too great yet.

+Another bottleneck is SwapBuffers.  It may be the limiting factor for
+many simple GL tests.
