AMD LiquidVR Thread

Information
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.

AMD LiquidVR™: Affinity multiGPU

My Fav

VR is something I am looking forward to trying! This Dinosaur footage has got me on the wagon..

I love the idea of VR, but not the wearing of heavy goggles. If they can make them lightweight and responsive enough then I am in.

My two main grips are.
1. I get headache from 3D glasses. So I hoping this isn't the same..

2. If someone is in same rooms has you, and you take it of to talk it will break the immersion.

Do you thing the headache is based on the refresh rate/latency? Have you tried the Occulus? That looks interesting, but again heavy.

I not tried anything VR yet but 3D am not sure what makes me get headache tbh..

Richer experience with Affinity Multi-GPU in Serious Sam VR: The Last Hope

LiquidVR is a suite of features AMD created to allow game developers to build great VR experiences using Radeon graphics. Affinity Multi-GPU is a key LiquidVR feature that gives developers the ability to control multiple Radeon graphics chips at once and to use them to help produce faster graphics or richer images. Serious Sam VR: The Last Hope is one of the first games to make use of Affinity Multi-GPU, thanks to a collaboration between Croteam and AMD.
