AMD comes with an SDK focused on virtual reality to reduce the latency when rendering content with Radeon cards. The manufacturer is collaborating with Oculus on development and has provided partners with an initial test version of LiquidVR.
AMD focuses on three things with the LiquidVR SDK: comfort, compatibility and appealing content. The company considers combating latency and warping under comfort. To reduce latency, AMD introduces Latest Data Latch and Asynchronous Shaders; the latter technique ensures, among other things, that information about headset movements is already updated for shader operations, after a previous frame has been rendered, for fast current display on the headset.
In addition, there is the Affinity Multi-GPU technology, which ensures that when using multiple GPUs, the image of each eye is rendered separately in parallel by each of the video chips. To increase compatibility, and thus ensure that Radeon cards work in combination with as many VR devices as possible, AMD adds Direct-to-Display. During startup, the image is displayed directly on the glasses and, for example, the possibilities for external screens of Windows are used.
AMD has released an alpha version of LiquidVR to partners and is working with Oculus on the developer kit.
