Yeah, this is almost certainly due to the terrible graphics driver
performance which jon nettleton is working to fix.

A pure-CPU benchmark (maybe something in Pippy?) would be a little
more reliable.  But anything involving floating point will suck,
because we're not using the hardware floating point support yet.  So
much software to tune...
