Yes currently only popular cards are supported: Pitcairn, Tahiti, Hawaii, Fiji, Tonga, Ellesmere, Baffin, Vega.
I will add other cards but a bit later.
For the meantime, could you at least let this new version run other GPUs on the board. I have rx550 and rx480 installed and I can't run it using the -di command or is there another way around this short of unslotting my rx550?
