When playing with war thunder and running radeon-profile on a =
A10-7850k and a
RX480, i notice that the GPU sclk scales from 300MHz to about 320-420MHz ...
very far from the max of 1.3GHz.

The GPU load is always low, about 20-30%, but if i manually increase the sc=
lk
to the max, i get a performance increase of about 40% and the GPU load is s=
till
about the same... i found that the GPU running above about 600-700MHz, i get
almost no performance increase... but the 300-400MHz is too low.

So for this game, amdgpu/radeonsi is not scaling as it should, probably the
game engine do not help. As far as i know, the game is mostly OpenGL 3.2, to
keep compatibility higher with older cards, if it matters.

I'm using kernel 4.12 and mesa-git 4db72852a16fc4a2a559255f9965e1d02e4f2b9c,
llvm 4.0.1 , on a slackware 64.

The game is free and have benchmark included, so anyone can test it.
