[Bug 1222602] Re: [gen3] Bad performance on GMA950 and GMA3150
I have tried the solution from comment #6 and it works. It would be
helpful to understand why this works. Digging through the comments it
looks like mesa uses not the GPU acceleration when the variable is not
set. This looks like a design error in mesa. Maybe mesa developers
should be asked about this. However, I have tried gnome-shell (before
adding the environment setting) and it worked like a charm indicating
that gnome-shell sets this variable on its own or initializes mesa
differently. Considering gnome-shell was freaking slow compared to unity
in 13.04. there must have been a not so wise change in unity.
