AMD Announces New LiquidVR Technology

AMD Announces New LiquidVR Technology

AMD announced an initiative to deliver the best possible VR experience for developers and users through new AMD technologies and partnerships. The first output of AMD’s initiative is LiquidVR, a set of innovative technologies focused on enabling exceptional VR content development for AMD hardware, improved comfort in VR applications by facilitating performance, and plug-and-play compatibility with VR headsets. The upcoming LiquidVR SDK makes a number of technologies available which help address obstacles in content, comfort and compatibility that together take the industry a major step closer to true, life-like presence across all VR games, applications, and experiences.


Introducing AMD LiquidVR™
LiquidVR™ is an AMD initiative dedicated to making VR as comfortable and realistic as possible by creating and maintaining what’s known as “presence” — a state of immersive awareness where situations, objects, or characters within the virtual world seem “real.” Guided by close collaboration with key technology partners in the ecosystem, LiquidVR™ uses AMD’s GPU software and hardware sub-systems to tackle the common issues and pitfalls of achieving presence, such as reducing motion-to-photon latency to less than 10 milliseconds. This is a crucial step in addressing the common discomforts, such as motion sickness, that may occur when you turn your head in a virtual world and it takes even a few milliseconds too long for a new perspective to be shown.

Low-latency head tracking to increase user comfort
If you turn your head and a scene takes too long to update, you’ll feel nausea or motion sickness. This is caused when it takes too long for a new perspective to be shown to your eyes, known as “motion-to-photon latency.” AMD is committed to ensuring that doesn’t happen when you use our hardware. AMD is providing a concrete set of tools to head-mounted display developers and content developers to help minimize the motion-to-photon latency that creates this sense of motion sickness.

Enable scalable rendering for more realistic experiences
Rendering near-photorealistic imagery in real-time at high resolutions in stereo at high refresh rates over 100 Hz is a challenge to even the most powerful GPUs and CPUs that are available today. With LiquidVR, users of AMD technology can build multi-GPU and multi-CPU systems with solutions available in the market today. AMD is providing powerful interfaces for developers to take productive advantage of all the CPUs and GPUs in the system for the best possible VR experience.

Compatible with a broad set of VR devices
We know that when it comes to devices, one size does not fit all. We expect a wide variety of VR devices to be in the market in coming months and years. Many of these devices will be new categories and will not initially have native support from content and operating system ecosystems. Our goal with LiquidVR is to help make the end-to-end installation experience as intuitive as possible – particularly for the display and GPU subsystem portions.

Power sensory integration to bring experiences to life
Achieving full presence in virtual environments involves innovations in basic senses other the sight, like hearing, touch and other stimuli like temperature, kinesthetic sense and balance. AMD sees a great opportunity to leverage our heterogeneous and scalable architectures to deliver acceleration to simulate all sensory experiences in years to come.
