🌟 Key Features

  • 🎯 Global Resolution Scaling: Change the internal rendering resolution for all 3D VR applications.
  • πŸ“ Advanced Rendering Controls:
    • Stencil Mesh: Optimize GPU resources by preventing rendering of hidden pixels.
    • Foveated Rendering: Optimize performance by concentrating resolution in the central focus area.
    • Texture FOV: Fine-tune the field of view for rendered eye textures.
  • ❓ Interactive Help: Integrated documentation for each setting to explain technical details and trade-offs.
  • πŸ“Š Optimized Presets: Choose from predefined values optimized for performance or clarity:
    • 384px: Ultra Performance
    • 752px: Performance
    • 1504px: Default
    • 2160px: Native Resolution
    • 2448px: Pico Specific
    • 2816px: Anti-aliasing
  • πŸ” Real-time Verification: Automatically verifies if the database changes were successful before rebooting.
  • πŸ› οΈ Modern UI: Responsive Jetpack Compose interface, optimized for VR landscape mode with a dual-column layout.
  • 🌍 Multi-language Support: Full localization for 27 languages with technical industry terminology.
  • πŸ” Root Safety: Uses content commands to safely modify the system's PVR configuration.

⛏️ Prerequisites

  • Device: Pico 4 Headset (Phoenix/China firmware supported).
  • Permissions: Root Access is required to apply changes to system files.
  • Superuser Permission: Grant root access when prompted by the app.

πŸ“– How to use?

  1. Download and Install the latest Pico3dResolution.apk.
  2. Open the app and grant Root/Superuser permissions when requested.
  3. Select your target resolution from the dropdown menu.
  4. Click "Apply & Reboot".
  5. The app will update the system database and verify the values.
  6. Wait for the headset to reboot. Your new resolution is now active!

⁉️ FAQ / Troubleshooting

  • Why does it need a reboot?
    • The Pico VR service and compositor only allocate their internal rendering buffers at startup. A reboot is necessary to force the system to read the new sdk_eyebuffer values from the database.
  • Will this impact performance?
    • Yes. Higher resolutions (e.g., 2160px or 2816px) significantly increase GPU load. Some games may experience frame drops or increased heat.
  • How do I verify the change?
    • You can use the PICO Metrics Tool to see the active "EBW" (Eye Buffer Width) and "EBH" (Eye Buffer Height) in real-time inside the headset.

How it works

This app works by using root access to modify the system's PVR configuration database (/data/user_de/0/com.pvr.configuration/databases/config.db). It targets parameters like sdk_eyebuffer, sdk_enableFFRBySYS, sdk_stencilMeshStatus, and sdk_EyeTextureFov in the RuleBean table.
