I don’t know if this is the correct plays to write this,
but I played around with some settings, since I experiences some lag at medium settings all over. Not always but at some of the larger regions, I found that the Area Display vanished if I lowered some settings individually.
But for performance I could lower the shade setting and the resolution to get a responsive game without loosing the Display Area.
I guess this is some thing one have to live with taking a chance playing at a MacBook slightly under the graphical minimum requirements.
But for you wondering I say It is fully playable using:
MacBook Pro (15-inch, 2019)
Processor 2,6 GHz Intel Core i7
Memory 16 GB 2400 MHz DDR4
Graphics Radeon Pro 555X 4 GB
Intel UHD Graphics 630 1536 MB
