The people who took over the glide support/devel, did it to make it work with MESA and specifically work on XFree4 - that means to support DRI (direct rendering interface). The bad thing is, that this DRI (or maybe their implementation of DRI in the glide drivers) does not allow exclusive access through glide (that is, fullscreen like it was in pre XFree4). So on the unix platform you are bound to go with : - XFree versions < 4 -> fast glide only mode (fullscreen only) -> MESA through glide * about 50% slower than glide only * no further development of MESA * fullscreen only * no specific support for v5 cards - XFree version >= 4 -> MESA through glide * about 75% slower than glide only (this is according to my v3 2000 experience)) * hardware acceleration in windows * v5 support * further MESA + XFree devel On windows it looks like this (im not that sure about the win platform): - glide access in windowed and fullscreen mode - opengl through glide with the opengl drivers of 3dfx (whatever quality they are) - this comes in almost as fast as the glide only version greetings norman _ __ __ > _/ \__/ \__/ Seth Galbraith "The Serpent Lord" \__/ \__/ \_ > \__/ \__/ \_ sga...@kr... #2244199 on ICQ _/ \__/ \__/ > _/ \__/ \__/ http://www.planetquake.com/gg \__/ \__/ \_ > > > _______________________________________________ > Crystal-main mailing list > Cry...@li... > http://lists.sourceforge.net/lists/listinfo/crystal-main |
