Bad performances with both catalyst and free driver

Hello,
With the  catalyst driver 15.20 and Xorg 1.16 my graphic card(hd 7870) is not used at her maximum for example in kerbal space program i have beetween 45% and 88% Gpu load but only in place like oceans normaly it don't exceed 75%, i have the same issue in war thunder,star conflict,robocraft but with unigine benchmark's (valley and heaven) it is good. I dont think it is normal . The cpu isn't overloaded it is a i5 3570.

What can i do?

remy18, try posting here : https://bbs.archlinux.org/viewtopic.php?id=57084

That thread is exclusively about the catalyst driver.

What makes you think this isn't normal? If vsync is on, and it usually is by default, rendering simple games such as Kerbal Space Program won't require full GPU power.

Vsync is off and it is laggy (sometimes arround 30 fps or less)
