XR Performance Specification

Overview

Performance requirements and optimization strategies for XR experiences.

Frame Rate Targets

Target: 90 FPS (VR) or 60 FPS (AR) Minimum: 72 FPS (VR) or 30 FPS (AR) Measurement: Consistent frame timing

LOD (Level of Detail) Strategies

Strategy

Distance-Based LOD:

• High detail for nearby objects
• Reduced detail for distant objects
• Cull objects beyond view distance

Performance-Based LOD:

• Adjust detail based on frame rate
• Dynamic quality adjustment

Asset Optimization

Optimization Techniques

• Texture compression
• Geometry simplification
• Animation optimization
• Occlusion culling

Network Data Streaming

Strategy

• Load critical data first
• Stream additional data progressively
• Cache frequently accessed data
• Preload based on user movement
