[SOLVED] Radeon Polaris poor performance after wake - Dell XPS 8930 Big Sur...

[brousseau6933]

Yes, verified, for OpenCore at least:

- standard "Plug.aml";
- AppleXcpmCfgLock and AppleCpuPmCfgLock unchecked. Weird as I'm supposed to to use AppleXCPMCfgLock as my CFG Lock/MSR 0xE2 is locked...

Go figure!

Let's now re-test Clover 5148!

Confirmed! I don't know, when re-testing with Clover (and thinking that the SSDT had fixed the bug), I've probably copied one of my "tests" EFI on the Desktop. In one of those, I had tried Acre FB injection and forgot about it...

So, to resume, the only thing needed is Acre FB injection (I know, totally counterintuitive as WEG is supposed to take care of that). Clover and OC works normally now!
