Here is an AHIII film of my box while flying.
You will note several instances of the film stuttering (even though I saw no such stuttering going on while flying) while I was flying.
The 1 instance that I would guide you to occurred at the 9:12 mark as that stutter is a screen pause\freeze that was captured in which you can clearly see the film skip ahead momentarily going out of synch then returning & I could clearly see the graphics motion stop completely for approx .5 secs then resume while I was flying.
Sending this to y'all for diagnosis to see if you can find anything from it.
PS--I have also provided a dxdiag of my box using the Crimson 17.8.1 drivers. You will find the AMD HDMI sound drivers are loaded along w\ the Creative SB X7 sound drivers...the AMD HDMI drivers are disabled in Win 10 so they aren't active. This is due to Win 10 continuing to reinstall the Windows version of these drivers on it's own after I delete them so I took a page out of Chalenge's book & disabled them instead to stop Windows from reinstalling them.
FYI........
