[No Metal acceleration on iMac 27" with Radeon Pro 580??]

Many thanks to all for your answers! Now this is cleared up for me...

[No Metal acceleration on iMac 27" with Radeon Pro 580??]

Hello,

 

yesterday I bought and installed Affinity Photo and I'm quite happy with it...

However, now I looked into the preferences and there I read (in German, of course ;-)):

"No compatible GPU" (I attached a screenshot)

That would be a surprise for me, because the Radeon Pro 580 is the fastest in the iMac-lineup, with the exception of the iMac Pro, of course.

Is that normal? Will it be fixed with future updates?

 

Greetings from Hamburg,

Sören
