I don't see anything strange in your EFI. I don't know why are you getting these low scores.
There are 2 ways to spoof the GPU id, SSDT and DeviceProperties. You are using deviceProperties now. Maybe you can try the other way, SSDT to spoof the device-id of the GPU, to see it so you...
I think 160000 - 19000 are good scores for RX 6900 XT. There is a few 200000 but there are a lot below 190000.
SSDT-VEGA imo doesn't change the scores, it's supposed to set the GPU more likely in a real Mac.
Carswell patch even can decrease the scores, as all the other patches. It's...
Maybe this issue has not to do only to the AMD.
About your EFI, the only thing I can propose to try is removing shikigva=128 boot arg since you have MacPro7,1 SMBIOS and I think it isn't needed.
Another thing, you can try a different SMBIOS, iMacPro1,1, to see if there is any...
GeekBench 5 score is good, perfect. The card seems to be well installed.
Why are you going to have crashes? This card is capable of doing what you are doing, notice that the CPU and mobo aren't so powerful but the RX 6600 XT is a medium level clearly more powerful than the RX 570.
Of course, having screen with image and not black screen is the first point.
Screen resolution as expected according to type and size of the display.
User experience working with macOS: smooth animations, no glitches, color quality…
Finally testing: get GeekBench 5, try out...
OpenCore 0.8.6 is out. You can download the new version from Acidanthera.

Thanks for your comments :)
All SSDTs must be compiled to aml to work with OpenCore or Clover. I write here the source code so users can read it.
Save the text as SSDT-VEGA.dsl, as plain text.
With MaciASL or Xiasl or iasl (command line) compile it to aml.
Alternative method to Henbury patch to avoid black screen with MacPro or iMacPro SMBIOS on Ventura (2)
There are some more advanced SSDT configurations such as SSDT-VEGA.aml which, in addition to creating devices, does so by mimicking the way real Macs are configured (EGP0 and EGP1 devices...
For the most of settings, I think so. You don’t need agdpmod=pikera in boot args either Henbury patch if using Ventura with MacPro or iMacPro SMBIOS.
Main difference between our mobos is the Intel wifi and BT, keep the kexts and settings in config.plist needed for it.
Alternative method to Henbury patch to avoid black screen with MacPro or iMacPro SMBIOS on Ventura with Navi 23 GPU (thanks Dreamwhite)
Using SSDT-BRG0.aml fixes black screen on Ventura with SMBIOS models lacking iGPU. This SSDT allows to define a missing pci-bridge device. With it, the Henbury...
