Hardware acceleration is... moody?

I succeed installing Big Sur on Lenovo G780 (with Ivy Bridge) and only things that dont work are built-in microphone, brightness control and hardware acceleration. Well, sort of. -- It works every second time i boot...

This just makes zero sense to me and i want to know if anyone know what could cause it.

Extra info>

GEFORCE dGPU disabled (iGPU enabled) (really would want to make the dGPU work somehow, but i dnt think it is possible)
WhateverGreen fully set up
CPU is i5 Ivy Bridge
