Just tried swapping back to the Pro Driver and now, no AMD driver load, I just get the generic Microsoft drivers.
Do not update your Vega FE to 18Q1.1, it is a website only download, after install it will disable any ability to change back to Gaming drivers. And if you try, it will not let you return to the Pro Drivers.
I've done two restores and resets and arrived at the same conclusion. I'm hoping other users have found a work around as AMD has failed.
I tried contacting AMD via the link you sent, the I'm not a robot feature for their security never let me pass, I tried over a dozen times. I could not get me issues submitted.
More AMD problems?
