Just wondering if Oculus already working toward Vulkan API implementation in Mobile SDK (that's what UE4 Vulkan dev told me) for UE4. I know it's kinda early since Android N isn't out yet, but nevertheless it's good to know we'll have (or have not) power of Vulkan with us in Gear VR soon (or not) :)Thanks

Just saw this: https://www.youtube.com/watch?v=jbCQI3DZ9w8Not really sure what to make of it :)

Take it easy ! I'm just asking ! I don't know how many people working on it so I can't really evaluate the time to adapt the Gear to the new API. And I'm not asking if they have finished but just some news ! Maybe the state, maybe an estimation date on when Vulkan will be supported as an alpha state and released to the "public" !

https://youtu.be/jbCQI3DZ9w8?t=2050The speaker Cass Everett says that you can hook the android api using buffer ques to a vulkan app running a single screen that will render in VR a single layer scene.

So, this happened: https://arstechnica.com/gadgets/2018/03/vulkan-1-1-adds-multi-gpu-directx-compatibility-as-khronos-looks-to-the-future/I really hope Oculus Go will have support for Vulkan out of the box and UE4 would be able to provide support for Go with Vulkan.

The current version of Vulkan is not suitable for Gear VR rendering due to a few key missing features (multiple queues, front buffer access, and more). We are working with Khronos to resolve this and I would expect UE4's existing Vulkan support to map reasonably well to the next version of Vulkan. Sorry but we can't give a timeframe for any of this, but it is something we are working on with Epic.

Oh, I see. Didn't think this iteration of Vulkan was not aimed at VR. Cool stuff, thanks!

It's been a about 3 months since this was posted. Is there an update about Vulkan and Gear?

No, Vulkan for VR isn't even ready. That's something to ask Khronos Group about.

Unfortunately, Vulkan on mobile still doesn't support front buffer or multiple queue rendering. We are working with Khronos to wire these up, but there isn't an ETA yet. My hope is that they will land in the next 3-6 months, but we can't promise that with any certainty.

Someone from UE4 community said they use Vulkan for VR on Google Daydream with Pixel phone. If API isn't ready for mobile VR, how is it even possible?

Google's compositor works differently from Gear VR's and they don't necessarily have to wait for front buffer access and multiple queues to arrive.

Where did you see someone getting Vulkan working for daydream btw? I had thought it was also not supported there yet.

Was talking to one dev on Discord chat. He said he uses Vulkan for his Daydream apps (he didn't specify whether it's UE4, Unity or custom engine).
