MP 1,1-5,1 Open Core Legacy Patcher HELP!

[Bloodklot]

Hello all!

I've installed Opencore Legacy Patcher v. 0.6.8 to install Monteray 12.6.8 on my Mac Pro 5,1 (Mid 2010)
It completed the install but I'm having graphic card issues. Right now it's not recognizing my graphics card. It displays fine on my 1440p monitor, but the mouse movements are choppy and slow. When I go to the Overview, it displays my Graphics as, "Display 14mb" Instead of my RX 6600 XT 8GB. (I reflashed this card on a PC before installing Opencore)

Initially after installation, it wouldn't recognize my keyboard or mouse so I installed the Opencore Post-Install Root Patch. This fixed the mouse and keyboard issues but not the graphics card.

A couple of things to note, I upgraded my previous OS (High Sierra) instead of a clean install. Also, I have a bootcamp partition on this SSD so I'm not sure if that's causing the issue? But right now, there is a Bootcamp partition, but I can't seem to boot into it. When holding down option on startup, it doesn't show up.

Any help with any of these issues would be greatly appreciated!

All I can find is that Navi 23 cards need agdpmod=pikera to output to a display. If that is already enabled then your best bet is to ask on OCLP's Discord channel.

How do you do that?

Is this after installing Syncretic's patched rom?
