To people running XP on a standard Macbook

BM runs better in OpenGL than DX7 simply because DX7 didn't life long enough as "3D API" so its drivers were never optimized enough. OpenGL thought is, as DX9, the current gen API and got optimized for years.

-> Max2D runs 20-100% faster on OpenGL than on DX7 with a real 3D card (ATI - NVIDIA)
