	There are a number of possibilities.  First, background processes (such
as commodities like screenblankers) may be eating some CPU time.  Second, some
calls might not be quite as fast due to relaxing certain limits on them (like
the longest line that can be drawn: was ~1024, now it's much larger).

	A good way to remove most extraneous variables is to turn off the
startup-sequence (hold both mouse buttons down, and disable it when the
BootMenu comes up).  Then run your benchmark.
