After many tests I noticed that versions 17.4.1 , 17.4.2 , 17.4.3 ,17.4.4 and 17.5.1 are bugged.All the games crashes with these versions,even mame crashes.(They make DirectX to crash)
17.3.3 and all the other versions of drivers work pefect.
I think a combination of amd drivers and windows updates that causes the probem
Amd Please fix it.
I have a Asus 390x Strix and have the same Problems.
Framedrops in Games, heavy load in Windwos and so on. I updatet my Asus tools, Windows 10 and so on.
I test it like georgex and it is the driver. 17.3.3. is fine with no problems, all newer Version causes problems a mass, mainly in DX9 Games!
