Hi all !!
I found the solution !!!
No more problems now with this : ClockBlocker Download Version 1.2-6.5
All the flickering problems and stutters are gone, I'm so happy !
I have the same stability and scaling than the catalyst 16.11, frequency of both cards are locked to 1000 mhz and don't move.
No more issues on all my games who has problem with crimson (BF1, overwatch, Battlefront,Titanfall 2 !!...)
