Would someone mind clarifying this:

My understanding was that this is partially cosmetic and really only necessary when using a non-Apple equivalent card (esp not necessary with SMBIOS’s that don’t run headless), or when needing GPU port definitions. I’ve been running with both this and the audio DP commented out b/c if they are enabled/defined, System Profiler reports Metal as “supported” and GB has a non-descript ID. When commented out, System Profiler shows “metal 3” and GB identifies the GPU correctly. IOW: default auto RadeonFB definitions seemed better. HOWEVER, seems pretty clear GB scores higher when it’s defined in DP.
I know there were some discussions about this a few hundred posts ago, but I don’t think I gleaned any clarity there.
I’m using a reference AMD 6900 XT BTW. I might have to freshen up on my WG reading again!
Thank you for any help,
