I updatet the Graphicsdriver from 15.6 (Batman driver) to 15.7 WHQL.
Since the Update i have Microstuttering in all games (tested with GTA 5, Bf4, Dirt Rally, Pcars, Witcher 3).
When i switch back to the 15.6 the games are running fine without stuttering.
-Frame Pacing ist activated in 15.6 and 15.7
-I dont changed the default Crossfire Profiles
-I removed the Driver with Display Driver uninstaller (DDU)
