Thanx Mald, I've got a AMD R7 260x with a device id 6658 and Vendor 1002 which is not supported by Catalina I am trying to fake ID but don't know at Opencore. There is a tutorial for SSDT-GPU-SPOOF I did it, but it doesn't seems to work. Other option is to inject Fake ID spoof to Device Properties at config.plist I tried but no luck or I just not making the right settings.

Sorry I don't understand, I tried changing device ID still not able to apply patch

0xFF, 0x67, 0x00, 0x00\n
0x5D, 0x66, 0x00, 0x00\n

Device iD is correct my GPU ACPI PCI location is correct I will send you a screenshot from windows device manager https://imgur.com/a/shx9Kd4 I am trying to spoof GPU my id 0x66581002 to 0x665D1002 that is close to my GPU that is natively supported in MacOSX. my GPU is XFX AMD R7 260X
