Valve has officially released SteamVR version 2.17.10, a targeted hotfix aimed at improving stability and refining specific rendering features. This update is now available for users on both Windows and Linux platforms. The patch addresses several technical issues that have impacted performance and reliability, particularly for those operating within the Linux ecosystem.

Stability and Rendering Adjustments

A significant portion of this update focuses on resolving stability concerns for Linux users. Specifically, the development team has resolved two distinct crashes that were previously affecting users with AMD GPUs. These fixes should provide a more consistent experience for Linux-based VR setups. Additionally, the update modifies how Contrast Adaptive Sharpening (CAS) functions within the software. By default, CAS is now set to off, and its application is restricted exclusively to VR game content. Users who previously relied on CAS for Steam Link or other applications will now need to manually re-enable the feature through the settings menu if they wish to continue using it.

Technical Refinements and OpenXR Updates

Beyond stability and rendering, the update includes a functional change for developers working with OpenXR. The interaction profile has been updated to utilize the term 'shoulder' instead of 'bumper' to ensure better compliance with current specifications. Furthermore, the update addresses a specific bug regarding the Motion Smoothing Force Always-On setting, which has now been corrected to function as intended.

Summary of Changes

  • SteamVR Version: 2.17.10
  • Linux Stability: Two crashes affecting AMD GPUs resolved.
  • CAS Default: Now set to off by default.
  • CAS Scope: Restricted to VR game content only.
  • OpenXR Profile: Updated to use 'shoulder' instead of 'bumper'.
  • Motion Smoothing: Fixed the Force Always-On setting.

These adjustments represent a maintenance-focused release intended to streamline the platform's performance and ensure that developers and end-users have a more predictable environment. Users are encouraged to ensure their Steam client is updated to the latest version to receive these improvements automatically. For developers, the shift in OpenXR terminology is a necessary update to maintain alignment with industry standards, and it is recommended to review existing interaction profiles to ensure compatibility with this change.
