[2022] Strange pattern on the map when I zoom in

Please attach here your Documents/Paradox Interactive/CK3/pdx_settings.txt .
From your Documents/Paradox Interactive/CK3/logs/ folder, attach here system.log , error.log

Also in Steam please click on Steam-Help-System Info, and paste everything there into a text file and attach that here.  

FYI the minimum requirements for this game on MacOS include:

• Processor: Intel® Core™ i7-7820HQ
• Memory: 12 GB RAM

Neither of which this machine meets, I'm afraid! All I can really suggest is turning down the graphical qualify settings as much as you can stand, even the resolution. And unload ever other app you can before starting the game.

Sorry about that!
