[Bug 771524] GPU reset and pipeline hangs randomly when using low-power tune

[GStreamer (GNOME Bugzilla)]

Well, it's a bit confusing: even though it works, GT3e performance is 10% below
GT2 (i measure only 132 fps 1080p for the i5 vs 146 fps for the i3 in low power
mode).

Note that it's worse on the PG mode (non-low power mode), i get 20% less
performance out of GT3e vs GT2 -- which should not be the cases since GT3 and
GT4 are supposed to have more hardware capability
(http://www.anandtech.com/show/9562/intels-skylake-gpu-analyzing-the-media-capabilities).

But overall, on GT3, FF mode is 50% faster than PG mode.

Should i file a separate bug for the fact that GT3e/GT4e is slower than GT2 ?
