QuoteWarhammer 40k Darktide is playable with AMD GPUs.

I've got tens of hours in Darktide on my AMD 6900XT, so I'm a bit baffled that those release notes.

Presumably there was a Proton 9 regression that introduced an issue? I used Proton Experimental and played right up to Christmas last year, so all Proton 8-based.

Yeah they're regression fixes, apparently I didn't note that. Fixed 🙃
