AMD Radeon Performance Enhanced SSDT

[hush-vv]

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

Hi @sselshamy - I think mattystonnie’s SSDT or CCMChris’ kext stopped working after the transition from Catalina to Big Sur (and Monterey).

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...
