Performance Profiler is a comprehensive runtime profiling tool for Unreal Engine. Place the PerformanceProfilerActor in your level and use the "profiler" console command to start/stop recording.

KEY FEATURES

• Real-time On-Screen Display - Color-coded FPS, thread timings, memory usage, and render stats displayed during gameplay

• CSV Data Export - Frame-by-frame performance data exported to CSV for analysis in Excel or other tools

• Blueprint Profiling - Track which Blueprint classes are consuming the most CPU time with tick counts and execution times

• FPS Heatmap - Spatial mapping of performance across your level, identify problem areas by position

• Thread Timing - Monitor Game Thread, Render Thread, GPU, and RHI Thread separately to identify bottlenecks

• Hitch Detection - Automatic detection and logging of frame spikes above configurable threshold

• VR Support - Track dropped frames against VR target framerate (Quest, PCVR)

• Unreal Insights Integration - Automatic trace recording for deep analysis

• Screenshot on Drop - Automatic screenshots when FPS drops below threshold

• Garbage Collection Monitoring - Track GC events, frequency, and duration

USAGE

1. Place PerformanceProfilerActor in your level

2. Play the game

3. Open console (~) and type "profiler" to start

4. Play through problem areas

5. Type "profiler" again to stop and save

6. Find results in Saved/Profiling/

OUTPUT FILES

• PerfLog_*.csv - Frame-by-frame data (FPS, threads, memory, draw calls, triangles)

• PerfLog_*_summary.txt - Session statistics summary

• PerfLog_*_heatmap.csv - FPS mapped to 3D world positions

• PerfLog_*_blueprint_stats.csv - Blueprint class performance

• PerfLog_*.json - JSON export for external tools

• *.utrace - Unreal Insights trace file

BLUEPRINT API

All functions exposed to Blueprints:

• ToggleProfiler(), IsProfilerActive()

• GetCurrentFrameData(), GetSessionSummary()

• GetHeatmapData(), GetBlueprintStats()

• AddMarker(), TakePerformanceScreenshot()

• ForceGCAndMeasure(), ExportSessionToJSON()

Perfect for identifying bottlenecks during development, QA testing, and performance optimization.
