[2020] 5700xt macOS Catalina Poor Performance

Note that this game is not supported on Intel video Macs , which covers most Mac laptops I'm afraid.

I doubt that's the issue with the iMacs mentioned above, but if you could all confirm your video systems and amount of RAM, thanks!

Hardware specs:
5600XT (6GB), i7-8700, 32 GB RAM

Note: this is true, to an extent, with all Paradox games in my experience (i.e., just runs better on a Windows with the precise same specs), but it's very very apparent in CK3, so I would guess there's a more serious issue at play

It is not the case that you can expect the same performance in Windows and MacOS on the same hardware. MacOS uses openGL which is a less polished and slower video standard than Windows' DirectX. That's why our published requirements for this an all our games are higher on Mac than Windows.

Which is no to say that CK3's performance on Mac cannot be improved, just to be clear!

Well that's interesting! And unexpected I have to say ... any further details on that?
