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