It's awesome that Vulkan exists and I really like the idea behind it. This will help a lot of game and engine developers; and questions like "Okay, so how do I trick
the driver into doing what I want?" or "Okay, so how do we develop a special case for this driver so this specific game runs a little bit better?" will hopefully be a matter of the past.
Maybe one day I'll get around to take a look at and experiment with it as well - but until then, I'll definitely be an excited spectator to anyone willing to do a Duality backend using it
