I'll try to explain.
1. In your first log (which is NO OK) I saw what Kodi uses High Quality Shaders (with DXVA rendering) which require more GPU resources.
3. The cases 1 and 2 are different -> the result is different also.
4. The GPU power state is managed by the driver. You just can set it's parameter in CCC. (I don't know how exactly. I have no AMD GPU) Just read this post http://forum.kodi.tv/showthread.php?tid=...pid2050914 and try to find same setting in CCC.
5. DX9 version requires a little more resources and driver decides to do not switch into power safe mode. DX11 requires a little less power and driver can decide to going into power safe mode which cause a performance issue. You can try to look at GPU states whit GPU-Z utility (Sensors tab).
