Mac users running MSFS in Bootcamp

Hi all, 1st post here and new to SIMS but loving this one. I’m just wondering if anyone out there is running MSFS on a iMac Pro and if so what settings you are using.
My system has the following:
GPU Radeon Pro Vega 64
CPU Intel Xeon W-2150B 10 Core 3.00GHz
64GB Ram
VRAM 16368MB HBM2 786 MHz

I do seem to struggle with FPS, usually around 30 but my GPU does seem to run very hot which I’m a little concerned about.

Anyway just looking for any tips on settings.
Thanks in advance.

Oh and my game keeps CTD suddenly now also but this seems to be common right now.
