High use Blender users tend to avoid AMD for the reasons you point out.
This leads to less updates due to amd users not being to interested in the community.
It is an issuw without any practicle solution. Because as I need a long overdue update. Again nvidia seems the only real choice.
Everyone is sorta forced to do that unless we can convince amd users to just try out blender and submit results.
So hi any AMD users who dont care about blender.
Give it a try and submit performance data please.
