@AndyTurfer hahaha, I just realize you’re the same guy I responded to in another thread. In theory we (because I also have a 4800h and turing GPU) should be able to use RTD3 on our ryzen machines, because they have all the neccesary to work (mainly the _RP3 _RP0 methods) but it looks that they are disabled on the nvidia driver. Only ryzen 5xxx series have this enabled, even though _PR3 and _PR0 are available even in 3xxx series AMD APU’s.
Regarding your question, _PR3 and _PR0 are used on other devices of the computers, so, you can verify if one of those results that grep shows you belongs to your NVIDIA GPU, for that open either sstd3 or sstd6 and look for the devices that they are into.
For example, mines belong to the device called _SB.PCI0.GPP0, that’s my GPU. Maybe yours have the same name.
