    Wow that DOTA2 Vulkan improvement, great stuff. This will bring it closer to the proprietary drivers.

        It's also possible that the proprietary drivers have improved as well as a result of 4.12

          Awesome! Its getting more and more mature!

          Not sure why Open GL is still faster than Vulkan in Dota 2. Maybe Vulkan is again just a wrapper around the whole thing instead of being fully optimized?

          If yes, the industry needs to step up their game.

            this shows that if developers provide good software hardware can excel. That's what linux operating systems need to excel.

              It's not a wrapper. Dan Ginsburg (the guy who mainly wrote the Vulkan backend in Dota 2) has been at many talks about Vulkan that you can find on Youtube. He has even commented on the Phoronix forums regarding Vulkan benchmarks a few times. Here's one such video https://www.youtube.com/watch?v=DWLkA6-wzj0 , here as well https://youtu.be/EX1RKhlOYmY?t=1h14m30s

              The Vulkan backend is just like the other render backends in Dota 2. The engine supports DX9, DX11, OpenGL and Vulkan all on the same level.

                    The second link is probably more interesting, as there Dan explains why Dota 2 isn't the perfect showcase for Vulkan, and why DX9 is still a tad bit faster in not-drawcall-heavy scenes.
