I don't think it's an intentional fallback. :) I was thinking that perhaps Q2 was setting just the right OpenGL state (texture env modes, etc.) to trigger a bug that causes an unwanted fallback. > try +set gl_ext_multitexture 1 +set gl_dynamic 0, you see that the bug > is related only to quakeII lightmap generation/uploading. That's a good suggestion. Doens't Q3 do some dynamic texture generation as well? -- Smile! http://antwrp.gsfc.nasa.gov/apod/ap990315.html ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
