Answer
Optimizing shader performance for AR headsets with limited GPU resources involves using efficient rendering techniques and minimizing computational overhead. Focus on reducing shader complexity, leveraging efficient texture sampling, and utilizing hardware-specific optimizations like foveated rendering.

// Shader optimization tips for AR headsets
// 1. Use lower precision types (e.g., half instead of float) where possible.
// 2. Minimize the number of texture samples and use mipmaps.
// 3. Simplify calculations and reduce the number of arithmetic operations.
// 4. Use baked lighting and pre-computed data to reduce real-time calculations.
// 5. Implement foveated rendering to focus resources on the user's focal point.

- Profile shaders using tools like Unity's Frame Debugger or Unreal's Shader Complexity view.
- Consider using instancing to reduce draw calls for repeated objects.
- Optimize the use of dynamic branching; avoid it if it causes performance bottlenecks.
- Test on target devices to ensure optimizations are effective in real-world scenarios.
