So far SteamVR could never activate async reprojection, which is more than annoying, because somewhat demanding VR games like Skyrim VR get 80% of the time capped at 45 fps.
I have read though that the RX 480 has at least no issues on Win 10, while I am still running on Windows 7.
So my question stays: Does my RX Vega 64 even support async or do I need specifically Windows 10 for it?
