Seems to be fully integrated to our Apple eco-system.

Issues:
Metal performance in single game that I have on Windows PC (World of Tanks) is much worst than under Windows, still playable but with medium as max instead of Ultra settings

------------------------
Used the EFI From AudioGod Aorus X570
What was changed:
Replaced the Lan Kext with RealtekRTL8111.kext
ALCID =11

During the install installer was hanging all the time. For some reason it was successful only after inserting into the device property PCIRooT(0x0)/Pci(0x3,0x1).. device and vendor Id for my GPU.
Based on recommendations from AudioGod laer I ve changed back this to the original entry. No real explanation, only worth to notice that this combo of MB and GPU had issues with earlier Windows updates when GPU driver was not working until it was manually reinstalled. (could it be that I got an NVRAM reset after this change that has solved the hanging and made the update successful?)
No chnge in benchmarks experienced with thiose two settings except that LUXmark in recognizing GPU only after changing back the settings to original one.
