The latest SteamVR update this week brings a number of new features, improvements and fixes.
The main content of this update is the drivers for the upcoming Valve Index VR headset and its controllers. It also includes UI settings and tutorial and Index software.
It also adds support for switchable update headsets, such as Index. Thus, the new headset from Valve has a default frequency of 120Hz, but it can be set by the consumer at the level of 80, 90, 120, or 144. 144 Hz is considered “experimental”. A higher refresh rate can make head and object movement in VR smoother than before.
Motion smoothing is equivalent to Valve’s Spacewarp asynchronous. When your GPU does not support the frame rate in VR, motion smoothing starts automatically. It causes the running application to display half the frame refresh rate of the headset and generates a synthetic frame after each real frame. Therefore, when smoothing motion, half the frames are real and half are synthetic. Whenever performance returns to normal, motion smoothing is disabled, and the application returns to normal rendering.
Motion Smoothing was launched in November. However, so far it has worked only on NVIDIA GPUs. Valve said that AMD support will come, and now it is here. The technology will not work on old R9 cards – you will need an RX or Vega GPU. If you bought a GPU before 2017, you’re probably out of luck. Otherwise, this feature should significantly improve the VR experience for cardholders such as the RX 570, especially in demanding games.
