Thanks for the link. I do note that its an August article.

The author says that Vega needs a driver improvement to catch GTX 1080 ( for example, The Unspoken seems WAY out of line -- even RX480 beats Vega). Since August, Vega has gotten some driver improvements that may be reflected in the benchmark I posted above.

Rumors are that the December Vega Adrenalin drivers will give a general boost due to unlocking some unused Vega features (of course that's not guaranteed -- its a rumor for now -- must wait and see what independent tests show).

Also, the article notes that the VR code limits FPS to 90 as part of normal operation. So, maybe in practice, anything over 90 does not get used regardless of what GPU is used. Then it comes down to price. Right now the Vega price is higher than I want to pay.
