To enable VRSS, open the NVIDIA Control Panel and select Manage 3D Settings, then scroll to Virtual Reality – Variable Rate Supersampling, and change the setting to “Adaptive”.
For advanced users, the Control Panel also offers an ‘Always On’ setting that applies up to 8x supersampling regardless of performance. Note, this may bring your frame rate below the VR headset’s refresh rate and impact your experience.
VRSS is supported by the driver--no game integration required--and can be applied to DX11 VR games or application that have forward renderers and support MSAA, and have been tested by NVIDIA. At the time of writing, over 20 games meet this criteria, including:
VRSS is only visible under 'program settings' in Nvidia Control Panel if one of the 20 games (or meet the rendering criteria) is present. It is not a global setting. Thus the Nvidia statement is incorrect. It should be: ....open the NVIDIA Control Panel and select Manage 3D Settings, Program Settings, then scroll to Virtual Reality – Variable Rate Supersampling, and change the setting to “Adaptive”.
So, if you install the 441.87 driver package, don't worry if the VRSS tab is missing. It will only show up if you add a game that meets the criteria.
