Best practices for Quest and PCVR

• Use Link for Developers and Meta XR Simulator to speed up development cycles.
• Use trilinear or anisotropic filtering on textures. See Textures⁠ in the Unity Manual for more information.
• Use mesh-based occlusion culling (see Occlusion Culling⁠ in the Unity Manual).
• Always use the Forward Rendering path or Forward+ (see Forward Rendering Path Details⁠ in the Unity Manual).
• Enable Use Recommended MSAA Levels in OVRManager. Generally, the recommended MSAA level is 4x if you don’t plan to enable Use Recommended MSAA Level.
• Enable Link Time Optimization⁠ in OVRManager’s Build Settings options (release builds only). As this increases build times, set this option only when creating final release builds.
• Watch for excessive texture resolution after LOD bias (greater than 4k by 4k on PC, greater than 2k by 2k on mobile).
• Verify that non-static objects with colliders are not missing rigidbodies in themselves or in the parent chain.
• Avoid inefficient effects such as SSAO, motion blur, global fog, parallax mapping.
• Avoid slow physics settings such as Sleep Threshold values of less than 0.005, Default Contact Offset values of less than 0.01, or Solver Iteration Count settings greater than 6.
• Avoid excessive use of multipass shaders (e.g., legacy specular).
• Avoid large textures or using a lot of prefabs in startup scenes (for bootstrap optimization). When using large textures, compress them when possible.
• Avoid realtime global illumination.
• Disable shadows when approaching the geometry or draw call limits.
• Avoid excessive pixel lights or use Forward+ which can speed up lighting computations.
• Use Dynamic Resolution to help reduce stale frames and increase visual quality by getting access to GPU level 5.
• Avoid excessive render passes (>2).
• Be cautious when using Unity WWW and avoid it for large file downloads. It may be acceptable for very small files.
• For Android apps with voice chat, you should use the Microphone APIs to avoid issues with Parties. For more information about Parties, go to the Parties and Party Chat topic.
