Bytter's Homepage - graphics programming and optimization
My main interests are graphics (mostly 3d), game and demo programming, so I collected a lot of links here that were useful to me. If you want your page, or any other cool page added, mail me. Some of this stuff, like the graphics and game programming links, is in some way related to DJGPP.
