Game Performance Analysis & Optimization

Analyze game performance and generate optimization recommendations: $ARGUMENTS

Current Performance Context

• Game engine: @package.json or detect Unity/Unreal/Godot project files
• Platform targets: !`find . -name "*.pbxproj" -o -name "*.gradle" -o -name "*.vcxproj" | head -3`
• Asset pipeline: !`find . -name "*.meta" -o -name "*.asset" | wc -l` game assets
• Build configs: !`grep -r "BuildTarget\|Platform" . 2>/dev/null | wc -l` platform configurations
• Performance logs: !`find . -name "*profile*" -o -name "*perf*" | head -5`

Task
