All versions of Adrenalin 2020 I have tested do this.
Driver installs with "Crossfire on" and no way to turn it off.
Happens with R9 Fury/Vega/RX590.
Happens with Intel Motherboards and Intel CPUs fron Haswell up.
I report this here as there is no other acceptable way to do so.
AMD Bug Reporting Tool offers no Data Trawl Opt out.
No way to report Bugs on WEB.
DDU in safe mode disconnected from the internet and installed Radeon™ Software Adrenalin 2020 Edition 21.1.1.
Turning Crossfire off results in PC reboot, and Crossfire still on.
Leaving Global Crossfire on and relying on turning Game Profile Crossfire "Disabled" is NOT a solution.
Doing that results in worse performance than turning Crossfire off completely in Global settings.
Motherboard :ASUS ROG Crosshair Hero VII.
MB BIOS 3003.
CPU: Ryzen 2700X.
OS: Windows 10 64bit Pro 2004 with latest patches and windows checks check o.k.
GPU1. Sapphire R9 Fury X.
GPU2. Sapphire R9 Fury X.
RAM 32GB Corsair 3200MHz
SSD Samsung 1TB QVO.
I am just reporting this.
I ask for no help.
AMD need to fix this.
I have "left" the AMD Community Forum.
Forgot to mention.
Leaving CrossFire on prevents AMD XConnect from working.
So I am unable to connect Thunderbolt eGPU Boxes to PCs which have Thunderbolt 2/3 support.
21.1.1 is another dud for me too on 5700 series. Max Vram clock speed error again. Reported the issues again 😕
