I would like to know about this as well.
I was expecting the Fury to be one of the supported for Async Reprojection in Steam VR. I see it's support in Rift but what about for Steam VR, is that coming soon? The Fury was labeled as a "Premium VR" device and I think that's a premium feature that is should have.
I am in the same boat. Bought a 390 over waiting for the 10xx series from nvidia. Had to format my PC and now with the latest drivers, my SteamVR games run like crap. I am on the edge of ditching AMD finally and picking up a 10xx series.
Yep, poor support for what is still the AMD flagship(!) GPU while Vega still isnt around.
When the Fury cards where released I bought one to show my support and my believe in new technology like HBM memory and my believe in AMD. The driver support of the Fiji chips still doesnt match what I actually demand from a flagship GPU. There should be way more optimizations than there are for the mid-price Polaris GPUs.
