But i am not going to stress you with this SSDT: if you have seen that VideoProc does not work the same, for me we can also leave the SSDT alone.

Although it's not an issue for me to revise the SSDT (I did say that it would take a couple of iterations), I agree that it has little chance of solving the problem.

EDIT
I noticed that some users of 6800-6900 use an ad hoc SSDT for the video card in order to have this situation that I show you in the screens (I'm showing you this to ask if it may have anything to do with my video working properly)

Which kind of "ad hoc SSDT"? Just defining all PCI bridges in the path?
If so, based on your IOReg screenshot you have three in a row
Please try the attached SSDT.
