I have the same issue.
I upgraded from windows 8.1 to 10.
My computer is as follow :
I7 3610 QM with integrated HD4000
AMD HD 6970m
Crucial M4 256gb SSD mSATA
HD graphics drivers number : 10.18.10.4252 got from windows update.
AMD drivers : Tried windows update and download directly from here with same results.
iGPU is always set even if in catalyst it's set as "high performance".
Tried different power plan in windows settings nothing changes.
I found a temporary workaround :
Disable windows driver auto installation.
Uninstall all catalyst and CCC.
Uninstall driver and delete it.
Then install Driver from 11/20/2014, version 14.501.1003.0000.
It works perfectly fine as supposed.
Thank you for answer.
My temporary solution is reinstall windows 7 (before your post) and exact solution is avoid to buy any product contains part branded amd.
I've had many problems with AMD products for the last 1 year
The FX-8350 processor does not work correctly with my favorite game. (Metin2)
970 North Bridge gets too hot and reset PC w/o overclock. (Asus m5a97 evo r2)
No properly prepared drivers for graphics cards. (Packard Bell laptop)
For 20 years I've always used AMD, and end now .
