BitBlt Speedup.

Skidracer says that the next version of BMax uses BitBlt to draw pixmaps. Blt is nice as it allows scaling. I want to know if the next version also supports BltFast for those times when you want a really fast render and no scaling. |

Is this going to work with OpenGL drawing to the backbuffer then? If so, if they have a handle on the backbuffer data, maybe they can provide this mem pointer to the user too. |

No idea how an OpenGL implementation would work, currently they write pixels to the backbuffer. |

The software implementation of IDirectDrawSurface7::BltFast is 10 percent faster than the IDirectDrawSurface7::Blt method. However, there is no speed difference between the two if display hardware is used. |

Fair cop. |
