Valve has introduced a new option in the SteamVR beta which now allows for per-application settings when using a VR headset.
This new option means that users can now tweak the resolution adjustment settings depending on what’s being used via a drop-down selector. This allows users to adjust the rendering resolution to give the best PC performance depending on the hardware and how demanding the VR application/game actually is a user is running. With less demanding games, the rendering resolution should be able to be increased for clearer visuals.
Valve’s update reads:
The first feature we are rolling out is per-application resolution adjustment. This setting is a multiplier on top of the current global application resolution from the Video settings tab in SteamVR. Per-application settings can be found on the Applications tab in SteamVR:
It’s worth playing around with this but remember this is in beta and you need to opt-in to the SteamVR beta to check it out. To do that head to SteamVR under Tools in your Steam Library right click and select properties, then select beta in the betas tab.
