When I run the Really Slick Screensavers on top of Mesa DRI on XFree on my Voodoo 3, I notice that the more complex screensavers which use features which are not accelerated by the Voodoo still run at a fairly decent frame rate. Does this mean that even if OpenGL app uses a mix of hardware supported and non-harware supported features, instead of defaulting to pure software, Mesa will handle the non-hardware supported portions of the pipeline while the vidcard will still accelerate those portions which it can? If so, then that's really cool, and will it be possible to have the same behaviour for Window drivers? |

That's basically true. If, for example, the application uses a 3D texture, the driver will fallback to software while rendering with the 3D texture, and return to hardware rendering whenever possible. > If so, then that's really cool, and will it be possible > to have the same behaviour for Window drivers? I'd expect Windows drivers to do the same thing. -Brian |
