for what is worth (I am not an expert)
I do use a z170 Pro Gaming with a i7-7700 since the motherboard support it out of the box without any modifications.
I enabled the Intel HD Graphics 630 and added in boot-args this entry: shikigva=80
after this the VDA Decoder is fully supported.
I believe having the right/best value for shikigva does the trick.
Now is it all perfect as a real Mac? not quite TV (app) is sill a bit templemental.
When I was using my old i7-6700, my 'iMac' was a iMac17,2
this is PCIe from my board. As you can see it is a z170 at heart

this is its current CPU.

Thanks for the reply.
The difference between yours and mine is that you have the i7 7700 CPU and I have the 6700 with the HD 530 iGPU on board which is not supported by Ventura. However everything works, except sleep, and I solved the VDADecoder faild problem with this suggestion taken from the Dortania OC guide and now the Apple TV also works very well.
- For error VDADecoderCreate failed. err: -12473 in Big Sur, forcing the AMD Decoder(on applicable systems) can help resolve this:
defaults write com.apple.AppleGVA gvaForceAMDAVCDecode -boolean yes ""
