+# Performance Targets - Dubai Metaverse
+
+## Overview
+
+This document defines performance targets and optimization goals for the Dubai Metaverse project.
+
+## Frame Rate Targets
+
+### Desktop (1440p)
+
+- **Target**: 60-90 FPS
+- **Minimum**: 60 FPS
+- **Ideal**: 90 FPS
+- **Hardware**: RTX 3070 / RX 6800 XT or better
+
+### Desktop (4K)
+
+- **Target**: 60 FPS
+- **Minimum**: 60 FPS
+- **Ideal**: 60+ FPS
+- **Hardware**: RTX 4080 / RX 7900 XTX or better
+
+### Cinematic Rendering
+
+- **Target**: Offline rendering (no FPS target)
+- **Output**: 8K EXR (7680x4320)
+- **Method**: Movie Render Queue
+- **Time**: Quality over speed
+
+### VR (If Implemented)
+
+- **Target**: 90 FPS
+- **Minimum**: 90 FPS (required for VR)
+- **Hardware**: RTX 4080 or better
+
+---
+
+## Memory Targets
+
+### GPU Memory (VRAM)
+
+- **Target**: <12GB usage
+- **Maximum**: 16GB (for high-end GPUs)
+- **Optimization**: Texture streaming, virtual textures
+
+### System RAM
+
+- **Target**: <16GB usage
+- **Maximum**: 32GB (for development)
+- **Optimization**: World Partition streaming
+
+### Storage
+
+- **Target**: <50GB packaged build
+- **Optimization**: Asset compression, unused asset removal
+
+---
+
+## Performance Metrics
+
+### Frame Time
+
+- **Target**: <16.67ms (60 FPS)
+- **Ideal**: <11.11ms (90 FPS)
+- **Measurement**: Unreal Insights
+
+### Draw Calls
+
+- **Target**: <5000 draw calls per frame
+- **Optimization**: Instancing, batching
+
+### Triangle Count
+
+- **Target**: <5M triangles per frame (with Nanite)
+- **Optimization**: Nanite, LOD system
+
+---
+
+## Optimization Strategies
+
+### Nanite
+
+- **Usage**: All static meshes where possible
+- **Benefit**: High-poly geometry without performance penalty
+- **Target**: 100% of static meshes use Nanite
+
+### LOD System
+
+- **Usage**: Non-Nanite assets, background buildings
+- **LODs**: LOD0-3 for primary, LOD0-2 for background
+- **Target**: All non-Nanite assets have LODs
+
+### World Partition
+
+- **Usage**: Entire Dubai district
+- **Cell Size**: 128m x 128m (default)
+- **Streaming**: Optimized per cell
+- **Target**: Smooth streaming, no hitches
+
+### Material Optimization
+
+- **Shared Materials**: Use material instances
+- **Texture Streaming**: Enable texture streaming
+- **Virtual Textures**: Use for large textures (optional)
+- **Target**: Minimize material complexity
+
+### Lighting Optimization
+
+- **Lumen Quality**: Adjust based on performance
+- **Shadow Quality**: Virtual Shadow Maps
+- **Light Count**: Minimize dynamic lights
+- **Target**: Maintain visual quality while optimizing
+
+---
+
+## Performance Testing
+
+### Tools
+
+- **Unreal Insights**: Profiling and analysis
+- **GPU Profiler**: GPU performance analysis
+- **Stat Commands**: Real-time performance stats
+
+### Test Scenarios
+
+1. **Empty Level**: Baseline performance
+2. **Full District**: Complete district loaded
+3. **Cinematic Camera**: Camera movement performance
+4. **Vehicle Driving**: Vehicle physics performance
+5. **NPC Crowd**: Multiple NPCs performance
+
+### Test Hardware
+
+- **Minimum Spec**: RTX 3060 / RX 6600 XT
+- **Recommended Spec**: RTX 3070 / RX 6800 XT
+- **High-End Spec**: RTX 4080 / RX 7900 XTX
+

+
+## Performance Targets by Phase
+
+### Phase 2 (Environment Production)
+
+- **Target**: 30+ FPS in editor
+- **Focus**: Asset optimization, LOD generation
+
+### Phase 3 (World Systems)
+
+- **Target**: 45+ FPS in editor
+- **Focus**: Lighting optimization, system integration
+
+### Phase 4 (Gameplay + Interaction)
+
+- **Target**: 60+ FPS in editor
+- **Focus**: Final optimization pass
+
+### Phase 5 (Final Polish)
+
+- **Target**: 60-90 FPS in packaged build
+- **Focus**: Final performance validation
+
+---
+
+## Performance Budget
+
+### Per System
+
+- **Rendering**: 60% of frame time
+- **Lighting (Lumen)**: 20% of frame time
+- **Physics**: 5% of frame time
+- **AI/NPCs**: 5% of frame time
+- **Other**: 10% of frame time
+
+### Optimization Priority
+
+1. **Rendering**: Highest priority (biggest impact)
+2. **Lighting**: High priority (Lumen can be expensive)
+3. **Physics**: Medium priority
+4. **AI/NPCs**: Medium priority
+5. **Other**: Low priority
+
+---
+
+## Notes
+
+- Performance targets are guidelines, not strict requirements
+- Visual quality should not be sacrificed unnecessarily
+- Test on target hardware regularly
+- Optimize incrementally throughout development
