So this is what I'm experiencing:
Flickering with crossfire + freesync enabled.
This is with 16.1.1 drivers.
For example, when I run World of warcraft, then alt-tab into windows, then run skype, then the desktop starts flickering, especially when I try to move the skype window.
The usage and frequency fluctuation with games, mostly older ones(DX9, DX10)...
Here are two vids showing the fluctuations. Both clock and usage.
