Indeed! Here are the results of the 'b' and 'B' benchmark with the
default settings before:

 Benchmarking...
 Result:  triangles/sec: 205098  fps: 28.5771
 Benchmarking...
 Result:  triangles/sec: 204282  fps: 28.4634

and after:

 Benchmarking...
 Result:  triangles/sec: 277690  fps: 38.6917
 Benchmarking...
 Result:  triangles/sec: 275819  fps: 38.4309

so the difference isn't that marginal as I thought.

Thanks for the tip Keith.
