-// The frames-per-second benchmark function on my machine does roughly:
-//
-//					OS:	10.1.5		10.2.2
-// CGDRAWBITMAP			15.2		36.6
-// CGIMAGEREF			15.0		27-135(i)
-// NSBITMAP				15.1		26.9
-//
-// (i) This seems to vary wildly between different builds on the same machine.
-//	   I don't know why, but I definately don't trust it. Recently I noticed
-//	   that it also varies by alpha channel strategy:
-//		kCGImageAlphaNone				36.6fps
-//		kCGImageAlphaPremultipliedFirst	112fps
-//		kCGImageAlphaNoneSkipFirst		135fps
+// Using Core Graphics is fastest when rendering 32bit data. Rendering CGImageRefs
+// allows us to use all the bitmaps that BasiliskII supports. When both Basilisk II
+// and OS X are set to 'Thousands', it can achieve over 500fps in a 312x342 window!
 
 /* When the BasiliskII video driver respects the alpha bits, set this to let us use */
