Please describe your issue:

Hi all. I have a problem with hardware acceleration. The Intel driver seems loaded by X11 (see log files), but I have very low performances (glxgears outputs 70 fps, while it'as 1500 fps on xiwi). I can't locate the issue. xorg-intel-sna.conf doesn't make any difference… Can anyone help in locating the issue?

Thank you,

Bests,

Camille.
