Many users are still stuck waiting to try medium after a bug prevents them from moving past the initial selection screen. My own experience is of staring at a left and right hand symbol wondering if this time I’ll find the right touch gesture to allow me access. reinstalls solve nothing nor do the latest updates. sadly medium is DOA for many.
As far as drivers, still on 388.59 for my 1070(laptop). Since there are no actual crashes this error may not be an easy one to sort. It's been reported by others but nothing shaking loose for solutions.
