Hey there red team. Your latest 18.7.1 July's driver never worked under Windows Redstone 6 Pre-Release version.
The last working set was your 18.6.1 and Microsoft update ones. Can you check it please upon next release?
I am a gamer and I need the latest and greatest in GPU resources. If you cannot guarantee it will not happen again, I think you should be faster in your alpha driver aka vanguard testing. I would gladly participate there if you accept me as to provide any support. I play more than 150 games and I always love beta software, I always was and will be a Windows Insider, even Skip Ahead one. Thanks.
