EXTREMELY BRUTAL.
All because creepto mining screwed up the inventory channels and made cards too expensive. The inventory is still messed up today. AMD is taking a hammering because of the same problem when they had their earnings call.
It would be great to have more GPU choices but as it stands Geforce cards don't support about 4 features from the latest Metal feature set. That would make it hell for developers because they have to write different code for AMD and Nvidia or they have to cut back.
So I doubt Apple will greenlight the drivers until they are rewritten for full Metal support.
Oh and no 10 bit output is an issue too if you need HDR.
A lot of these folk might be Hackintosh users so their voice doesn't carry much power. Apple will probably try to analyze demand from real Mac users.
