So I think my stuttering after wake from sleep on my HTPC (deck image) is due to games coming back from sleep and using the integrated GPU instead of my AMD GRE. Is there a way to completely disable the integrated GPU?
I don't recall seeing option for that but will check...if I find more than one node can I disable one of them? In a game (e.g. Helldivers 2) it shows my GRE and integrated graphics. After sleep if I toggle the card used the FPS goes back to normal.
