I've tried to use the Dortania guide to spoof the Device ID to an R9 390x as described but it doesnt seem to be working
When I use this path the PCI GPP bridge gets changed not the r9 390 as the bridge is PCI0/GPP8
where as i read the GPU as PCI0/GPP8/GFX0
I use this GPU_SPOOF
but still no luck
Any thoughts?
