Yes instead of 1 technique that kinda works for everything, they have a A.I optimise how to do it best for each title.
Its a better technique than Checkerboard rendering that the PS4pro does, but its in sense the same thing.
About the power load:
Does anything about this card screams "hey, I consume less power than it seems!"? My, my.
Besides, anyone can do this peak consumption stuff. Vega's particularly good on it.
Face it, the thing's dead on arrival. In fact, it is so dead AMD has no business calling it a "live stream", amirite?
