Hello !
I finaly did manage to get performance improvements by editing DeviceProperties straight into config.plist
I hit the 90K with geekbench and got a ~10% speedup in davinci resolve!

BUT

I noticed some black artefacts in my picture preview in davinci resolve when running heavy GPU process.

SOOOO

I rolled back to the previous config file and I will investigate further in the future. Maybe there are some other parameters that I could try.

Thank you so much for helping me out on this !!
Black artifacts in high resolution previews in DaVinci may be due to overclocking parameters that are not suitable for your GPU. You can try to use the table "Radeon_VII.xlsx" to adjust the overclocking parameters. and replace the value in "PP_PhmSoftPowerPlayTable". The value in "PP_PhmSoftPowerPlayTable" needs to be replaced using the "OpenCore Configurator" tool

I highly recommend you all to try the new AGPMInjector method!


Look for the releases in order to download the app.
New?

Of course you did not check the releases...
It's much newer than this enhanced SSDT method, it is more simple and it works like a charm...

I have an Sapphire Nitro+ RX580 running on an i9 on with a Z490 board as iMac20,2.

For me the SSDT didn't really work as expected, expecially the power consumption in Big Sur and newer. It was around 100 Watt in idle – even with the additional DAGPM.kext (same for Pavo's AGPM kext).

So I've read the complete thread to figure out a solution. Turns out that the DeviceProperty injection method explained on Page 35 and following works much better than the SSDT+kext in my case. Especially power consumption in idle dropped from 100 Watts to around 70.
