I'm writing so many posts, I'm sorry.
I would like to inform you that the issues seems fixed.
Now I get 38000 OpenCL and 53000 metal just after boot, without the need to sleep/wake.
I was testing Sidecar and I just changed my SMBIOS to iMac19,1: that has solved the problem.

All right, my last post about it since I fixed RX 580 performance:
I resetted my SMBIOS to MacPro7,1 since iMac19,1 was giving me some problems with AMDRyzenCPUPowerManagement (And sidecar still doesn't work).
When I booted with the old SMBIOS the sleep/wake bug was still here.
So I added this string to my boot-args (You need WhateverGreen):
Code:
shikigva=160 shiki-id=Mac-AA95B1DDAB278B95
shikigva to 128 so I have FairPlay 1.0 hardware acceleration and 32 to swap board id (128+32=160)
shiki-id to Mac-AA95B1DDAB278B95 that correspond to iMac19,1.
I rebooted 2-3 times to make sure that it works and I got just after boot a 40000 OpenCL and 53000 Metal (Little less than windows but I'm still happy).
Still need RadeonBoost to get 1000-2000 more points.

Much easier with device properties, no rename/ACPI patching necessary.

On my 5500 XT

Hi, Aluveitie
I am building with Gigabyte B550 and Asus RX5500XT 4G.
It works without any problem with reference to various people.
However, the RX5500XT has a Metal score of 27000.
I want to add Plistdevice properties.
Could you share the Config.Plist or Plistdevice properties part?

@comset Here are my device properties I've used. They improve Geekbench scores, but don't really improve performance otherwise.
