Benchmark

Benchmark

The Benchmark tab compares editor scene performance before and after building instances.

Use it as a practical before/after check, not as a replacement for full Unreal Engine profiling.

Capture workflow

Benchmark capture workflow

Recommended benchmark flow:

  1. Scan and prepare the Build Plan.
  2. Open Benchmark.
  3. Click Capture Baseline before building.
  4. Build instances.
  5. Return to Benchmark.
  6. Click Capture Current.
  7. Read the Delta section.

Keep the viewport still while capture is running.

Reading results

Benchmark results

Important fields:

MetricHow to read it
Avg FrameAverage frame time during the capture window. Lower is better.
MedianMiddle frame time. Lower is better and often more stable than average.
P95Slow-frame percentile. Lower is better for hitch detection.
Avg FPSFPS derived from average frame time. Higher is better.
Median FPSFPS derived from median frame time. Higher is better.
P95 FPSFPS derived from P95 frame time. Higher is better.
Draw CallsEstimate from the Build Plan, not a direct renderer measurement.

Delta section

Delta compares Baseline and Current.

Positive signs can differ by metric:

  • Lower frame time is better.
  • Higher FPS is better.
  • Lower draw-call estimates are usually better.

Read Avg Frame, Median, and P95 together.

Benchmark reliability

Benchmark results can vary because the editor is not a controlled runtime environment.

For cleaner comparisons:

  • keep the viewport camera still;
  • avoid moving selection during capture;
  • wait for shader compilation and asset loading to finish;
  • run the same camera angle before and after build;
  • compare multiple captures if results are close.
