I ran it with GL_FOG forced off, seems that did the trick, Intel is back to
being faster than my discrete NVidia card.  Haha, the irony.  Well thanks to
software side state checking, I managed to get this fixed so now we know it's a
fallback of some kind related to fog with glBitmap, not sure if we should mark
as resolved or if it should be left open until the issue is looked at?

Anyway thanks for all the help guys!  (or gals if any)
