How to use this test

  1. Click 'Start FPS Test'.
  2. Select object count density (e.g. 500 or 2,000 particles).
  3. Watch real-time FPS graph and frame time distribution.
  4. Review Average FPS, Minimum FPS, and Frame Drops.
  5. Click 'Stop Test' when satisfied.

How to understand your result

Looks good: Rendered consistently at display refresh rate with minimal stutter.

Troubleshooting: what to try next

  • Disable browser hardware acceleration if severe stutter occurs.
  • Ensure your laptop is plugged in; battery limits GPU performance.

What this test cannot tell you

Measured FPS reflects browser composite frame rates, not standalone DirectX/Vulkan game FPS.
