Hello everyone.
I just bought a new Gigabyte 6900XT that is replacing my old Asus Vega64 card. The Vega64 card was working great on Monterey ( HW acceleration, resolution etc.. ), the 6900 is giving me some issues though.
I'm running Monterey 12.3.1 on Opencore 0.8.5 ( tried on 0.8.0 too without success ) using iMac19,1 as smbios.
Seems that the original Apple drivers is getting loaded and the path in IoReg is the right one. But I get the wrong underscaled resolution for the monitor and the HW Acceleration is off. The system is pretty laggy too.
I've tried to change the smbios to iMacPro1,1 and MacPro7,1 resetting the NVRam, but nothing changed.
What can I try to get the 6900 working?
Thanks for any help!
My build:
Monterey 12.3.1 on Opencore 0.8.5

i9 9900K
Gigabyte 6900XT GV-R69XTAORUS
