Forbes got some info and a few slides about AMD's work at improving VR tech.

Forbes said:
Today AMD introduced LiquidVR, a new platform designed for immersion and responsiveness in virtual reality environments, and an initial talking point in that larger argument.

Oculus, one of the pioneering forces in VR, seems pretty excited about it:

“Achieving presence in a virtual world continues to be one of the most important elements to delivering amazing VR,” said Brendan Iribe, CEO of Oculus, via email. “We’re excited to have AMD working with us on their part of the latency equation, introducing support for new features like asynchronous timewarp and late latching, and compatibility improvements that ensure that Oculus’ users have a great experience on AMD hardware.”

That’s the kind of quote that could sell GPUs. But let’s look at why LiquidVR is important before detailing what it is.

AMD released the Alpha version of their LiquidVR SDK (software development kit) to developers today. It introduces a batch of features that, according to the company, will be exclusive to AMD hardware — much like Nvidia and their GameWorks platform. If you’ll allow me a brief moment to get technical, they include:

Hardware-Accelerated Time Warp (the coolest name for anything I’ve heard in months), which uses updated information on a user’s head position after a frame has been rendered and then warps the image to reflect the new viewpoint just before sending it to a VR headset. I’m not sure what half of that means, but it effectively minimizes latency which is important.
Affinity Multi-GPU, which lets developers harness multiple graphics cards to improve frame rates in VR software by letting them assign specific tasks to each GPU. So, imagine one GPU doing the rendering work for each eye and then combining them into a single, smooth 3D image.
Direct-to-display will allow things like booting directly to a VR display, and enhancing extended display features inside of Windows.

Affinity Multi-GPU - perfect for dual GPU cards, what with all the options Mantle and DX12 are providing.
 
Yup the demo running LiquidVR was on a 390X Fiji board. It is rumored the card will be shown off tomorrow and this is exactly the reason why Nvidia showed the Titan X unexpectedly.

Be interested to see what the 390x will be like if they do preview it. Not that I am upgrading anytime soon. My 4K performance has been amazing with QuadfireX
 
See if this wasnt another Gameworks I'd have more interest.
I hate market segregation caused by one mfr blocking another.
All this does is make us hate GPU mfrs and get pissed off that the games we paid for dont perform as they should when we have bought decent hardware.
Hmph.

I think it is more similar to moving towards of merging of proprietary features into a standards group.

Much of the features/technology of AMD's and Nvidia's VR solutions are extremely similar. The push is for open development and widespread compatibility because no one knows who the winner will be. No one wants to have another HD-DVD on their hands.

Valve is giving away their technology called Lighthouse. They are treating it like USB. So even though all VR tech is in it's infancy, there are forward thinkers that value open standards.

Razer is doing the same thing. Oculus, to an extent is doing the same.
Edit- Well with other types of tech they are working on, not the positional awareness/tracking that Valve is talking about.
