R.i.p Mantle or Mantle Evolved?
Detail...details guys
However, if you are a developer interested in Mantle "1.0" functionality, we suggest that you focus your attention on DirectX® 12 or GLnext.
One don't say 1.0 if there isn't a newer one...
Matt will we see the new demo on GDC? The one replacing starswarm.
