Yes currently only popular cards are supported: Pitcairn, Tahiti, Hawaii, Fiji, Tonga, Ellesmere, Baffin, Vega.
I will add other cards but a bit later.
It was my favorite miner (v9.7), thank you anyway... As I see in recent readme file: "This version is for recent AMD videocards only: 7xxx, 2xx, 3xx and 4xx, 1GB or more" - I have some AMD HD7790 (7xxx!) cards but can't use them right now with 10.x/11.x versions on XMR ("-pow7 1"). And of cource all other old cards (57xx/58xx)
Is it no chance to support them? Please-please-please bring it back!
