OK, today i made another benchmarks: drm-next, mesa-10.3.2. First without any
changes, second with `git revert 59bc1d8`:

without any changes         with `git revert 59bc1d8`
FPS:      14.3                 19.1
Score:    599                  801
Min FPS:  2.1                  12.2
Max FPS:  30.7                 30.7


Honestly, the difference is incredible. Can't believe such a small change has
such a big impact. It even seems with the commit the performance get's worse
over time - never had under 600 points before..

@Michel: mesa-10.3.2 does indeed help. I already had minor lag's/stutters in
the past (pre-3.17) - that was "normal" for me, but now i have ZERO lags. The
complete benchmark was done without one major lag. AWESOME :)

If anyone is interested i can also create videos, so you can see the
differences :)
