It works fine with me, even if I detach the principled volume in render view mode

welcome, no you don't have to. If you want to you can completely remove the current driver using amd cleanup utility and install the new one.

the WHQL stands for "Windows Hardware Quality Labs" it basically means that Microsoft tested this driver and it met the standards of Microsoft, and it is compatible with their operating systems.

Hi, today the new update "Adrenalin 2020 Edition 21.2.1 Optional" came out for my GPU rx 5700xt and it solved the problems with volume shaders, in the past I couldn't render any volume shader at all I tried all the different versions of the GPU drivers and Blender versions too.
