Padoka PPA finally updated, version 2.1~git1600912162600.546bc07~x~padoka0.

Here the bug continues. This time a take the time to test in various games.
Valve's Source Engine take less hit by this bug, only about 50% loss in
performance. But others, like American Truck Simulator and Unigine Valley take
a 70/80 % hit in loss of performance, both cannot pass 10/12 FPS in a beefy
Core i7 and a R9 290.

I tested in kernel 4.7.3 and 4.8-RC6.

I have hit this bug too with r7 260x. I don't have time for bisecting but with
Mesa from 7th september the perfomance is fine . I ve also noticed some
perfomance delta dif between the 12.0.2 release and git from september 7th .
With dirt showdown with kernel 4.6.7 and LIBL_DRI3_DISABLE, I get an average of
35~30 framerates with Mesa from 7th september I get 50 fps. 
Anyway here I have setup a repo if someone else on Opensuse is hitting the same
bug.
