help getting r9 390 working on Monterey

Hi everybody.

This is the first hackintosh that I've ever made (not considering the already made efi for my Thinkpad). I followed carefully the dortania guide and as a result I've got a working hackintosh, with the "only" problem of hardware acceleration. I've tried using the sstd-gpu-spoof exactly how it was written in the dortania guide. I've tried spoofing the gpu in the DeviceProperties in config.plist but nothing worked. With sstd-gpu-spoof nothing changed (it was declared in the config.plist), while with DeviceProperties it's spoofed, but with a wrong id. I've tried everything I could find online but still I can't get the gpu working.

any help would be appreciated
