Jose was working on some MMX code that was currently disabled in the Mesa source due to bugs in the coding. So he fixed problems that could not come into effect for your case. With that fix you might spot some speedup with an MMX capable CPU if you are running specific mesa demos on it. Concerning the tunnel demo. As long as fogging is not required (at least i think it is not) for the rendering of the alpha blended help texts and the other informatinal texts, it would be the best if you just disable fogging for drawing these elements. Consider that mode turn-off as a fix for some sub optimal application coding. (I should have a look at that source and check if or why its not alredy done in that demo...)
