Phonix Point OSX - No graphic device to use

Hello,

Not sure if this is a bug or just not implemented yet, but I bought the OSX version running it on Mac mini 2018, 16GB RAM, Core i5 and with an external GPU connected to Thunderbolt 3. It’s a Radeon RX 580.

This works very well in all modern games I play, but in this Preview of the game, first of all, I cannot even select GPU device at the start screen, it’s greyed out and secondly it’s very visible in the game that it’s not using the external GPU. Also, in other games when it’s used, the fans start spinning on the eGPU, but not at all here.

Is it just not implemented yet or a bug? If the latter, what info do you need from me more than I have already given?
