I recently bought a sapphire rx 6600 video card on my computer, although it is Mac compatible, no matter what I do, I either got a black screen error, or it worked quite slowly.
I tried the command agdpmod=pikera, the henbury patch and I loaded the standard weg&lilu kext.I also tried to install 12.3.1 & 12.1, the result is the same. Every idea helps me. What can I do? I've been struggling for days.
My system specifications:
-i5 8600k
-16 GB DDR4 RAM
-Hikvision 1TB NVME SSD
-Asus Prime H310M-e r2
Sapphire Pulse RX 6600 8GB
Also dual monitor setup with display port
