Have you tried Screen Mirroring from Big Sur to Apple TV?

I’m using iMacPro1,1 with only AMD GPU (no iGPU in my CPU)
shikigva=128
I’ve the sound but not the video
It used to fully work in Catalina
Any idea what I can do?
The same with shikigva=80 with AppleTV 4K, but OK with AppleTV A1469 (3rd generation).

1. Yes - pretty confident that went okay, especially cause it works with the tbtOnPch SSDT.
2. Even pre-connected devices. It has always been pretty funny, hence why I was exploring the options here. Usually, if I disconnect AC from the comp, it takes sometimes MANY cold boots and reboots to get Thunderbolt working again (on pre-connected devices). Once it is working, it connects consistently on every reboot as long as AC power is not lost. It could be that I just need to keep cold booting and rebooting for a while longer, but it has never been quite this bad.
3. Yes, they worked without an SSDT and also with the SSDT-TB3 from another thread on this forum.
It may be a good idea to perform a CMOS Reset, which will require BIOS parameters to be configured again.

I'll try that later today and update this post.

is there a way to check the signal strength in -db of a wifi access point, either from OS X or an I-device?

Please also post a new IORegistryExplorer file as detailed below. There's no hint of the GC-Titan Ridge in the previous IOReg file, hence a new one is needed.
  • Please check that GC-Titan Ridge card is installed.
  • Disconnect the THB_C Thunderbolt header cable if it is connected.
  • Hold the card vertically with PCI pins facing the floor and connect the Top and Middle pins of the 5-pin J1 header with a F/F jumper wire. This will force the card to turn on.
  • Disable any existing Thunderbolt SSDT.
  • Boot the system and log into macOS.
  • Run IORegistryExplorer --> File --> Save As... and post the saved file.
Here is my IORegistryExplorer content. No Thunderbolt SSDT applied.

That's much better. GC-Titan Ridge is on PC01.BR1A. Please try the attached SSDT in combination with SSDT-DTGP.aml.
  • Copy the attached SSDT to OC/ACPI folder.
  • Add a reference in config.plist --> ACPI section.
  • Check that a reference to SSDT-DTGP.aml still exists.
  • Disable any previous Thunderbolt SSDT.
  • Reboot.
  • Post a screenshot of PC01.BR1A section of IORegistryExplorer to confirm.

Hold the Option key down and click the Wireless icon in the menu bar.

Exactly! Just look at RSSI (Received Signal Strength Indicator). Then have a look at this post to decode the value:

RSSI Summary Description
-30 dBm Excellent Max achievable signal strength. The client can
only be a few feet from the AP to achieve this. Not typical
or desirable in the real world.
-67 dBm Very Good Minimum signal strength for applications that
require very reliable, timely delivery of data packets.
-70 dBm Okay Minimum signal strength for reliable packet
delivery.
-80 dBm Not Good Minimum signal strength for basic connectivity.
Packet delivery may be unreliable.
-90 dBm Unusable Approaching or drowning in the noise floor.
Any functionality is highly unlikely.
