AMD’s new Crimson Software 17.4.1 isn’t a particularly meaty driver release, but the improvements it does come with are quite interesting, including updates for smoother VR projection and new connectivity options, along with a small handful of bug fixes.
On the Rift side of the VR font, this driver adds support for Oculus’ Asynchronous Spacewarp technology on Radeon R9 290 series and R9 390 series cards. In short, Oculus’ ASW is a feature that takes two frames and extrapolates a new frame in between, resulting in a much smoother frame rate – an especially useful feature for users who don’t have the fastest graphics cards but still want to get into VR and have a pleasant experience. For a more detailed explanation on how ASW works you can read our detailed writeup.
Similarly, AMD also added support for SteamVR Asynchronous Projection for Radeon RX 480 and RX 470 graphics cards, just like it promised last month. This feature will smooth out playback on the HTC Vive but, for the time being, it only supports Windows 10.
For connectivity, the driver adds support for DisplayPort 1.4 HBR3, 8K at 30Hz over a single cable, and 8K at a full 60Hz over two cables.
