I will try. Thank you very much

Section 3.5.2 of the ASUS User Manual in English, shows you how to choose the GPU.

I saw that but there is nothing about iGPU, PEG (PCi Express Graphic) and PCI ...
I tried both variants, same thing...

With this flag no crashing but uses only 20% of GPU, That is on Monterey
Same bootloader, on Mojave (I have dual system) same version on Davinci Resolve use 100% GPU and rendering in a blink of an eye... Is there a way to fix this?

Edit:

Davinci no crashing, but FCPX freeze and crash. So again, not working even with bootflag
