I should clarify: the texture mem available is currently determined by the max resolution configured and the AGP size (if it's an AGP card, of course), but you'll get better framerates by setting games to use a resolution lower than 1024x768. I tend to stick to 640x480 or maybe 800x600 for games, but my desktop is 1024x768. > If textures > cause massive slowdown, then the app is probably using a texture > environment that's a fallback.
