AgpSize is the amount of _system_ memory allocated from the AGP aperture, it's not limited by the amount of RAM on the card. The possible values are 4, 8, 16, 32, 64, 128, and 256 (MB). The default is 8. Increasing the value gives you more space for textures in AGP and could decrease the amount of texture swapping. BufferSize probably isn't going to be that useful at the moment. It sets the total size of the DMA buffers to 2 or 1 MB (with 2 being the default). Reducing this to 1MB will give you more space for textures, but will probably reduce performance since apps will have to wait for buffers more often. -- Leif Delgass http://www.retinalburn.net ------------------------------------------------------- Bringing you mounds of caffeinated joy >>> http://thinkgeek.com/sf <<< _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
