Introducing AMD Liquid VR Liquid VR is an AMD initiative dedicated to making VR as comfortable & realistic as possible by creating & 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, Liquid VR uses AMD's GPU software & hardware sub-systems to tackle the common issues & 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 & it takes even a few milliseconds too long for a new perspective to be shown.
