John Carmack is the new CTO of Oculus VR. He’s still coding in his new position though, and yesterday he posted an interesting tweet about Vulkan, mentioning “impressive improvements” on early Vulkan drivers while running native code. He also added that it will be a “big win” once Vulkan gets proper support from popular engines such as Unity 5 and Unreal Engine 4. Last month, Khronos announced that Vulkan 1.0 was almost complete and it would be released in early 2016, with a slight delay over the previous schedule.
