Only very high end devices currently have the required chipsets.\r\n\r\nVulkan is a natural for VR, since it allows async GL pipelines to control regions of a screen (eg. VR stereoscopy). There is dramatic performance gain when not having to render the two targets and then render them both to a screen target. Far fewer context switches, too.\r\n\r\nI am cautious about \"Daydream\", since it sounds like a least favourite flavour of corporate Kool-Aid. The reviewers have noticed there are not any real specs for it.\r\n\r\nIt seems to be the Cardboard SDK rewritten in Vulkan, installed in the kernel, and directed toward a dedicated HMD that has yet to be finalized.\r\n\r\nIs a deep-dive into Vulkan on Rajawali's roadmap? Seems like a mountain worth climbing. If  Daydream is Kool-Aid, Vulkan could be beer.\r\n\r\n\r\n#### Steps to Reproduce\r\n\r\nSlam head against another learning curve. Beer. Repeat.\r\n\r\n#### Trace or Log Output\r\n\r\nTBD\r\n"},"comment":{"url":"https://api.github.com/repos/Rajawali/Rajawali/issues/comments/237596349","html_url":"https://github.com/Rajawali/Rajawali/issues/1687#issuecomment-237596349","issue_url":"https://api.github.com/repos/Rajawali/Rajawali/issues/1687","id":237596349,"user":{"login":"jwoolston","id":2993125,"avatar_url":"https://avatars.githubusercontent.com/u/2993125?v=3","gravatar_id":"","url":"https://api.github.com/users/jwoolston","html_url":"https://github.com/jwoolston","followers_url":"https://api.github.com/users/jwoolston/followers","following_url":"https://api.github.com/users/jwoolston/following{/other_user}","gists_url":"https://api.github.com/users/jwoolston/gists{/gist_id}","starred_url":"https://api.github.com/users/jwoolston/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jwoolston/subscriptions","organizations_url":"https://api.github.com/users/jwoolston/orgs","repos_url":"https://api.github.com/users/jwoolston/repos","events_url":"https://api.github.com/users/jwoolston/events{/privacy}","received_events_url":"https://api.github.com/users/jwoolston/received_events","type":"User","site_admin":false},"created_at":"2016-08-04T15:51:19Z","updated_at":"2016-08-04T15:51:19Z","body":"There are only 4 goats....however around 500 quail and a bunch of rabbits.
