Read what average FPS misses

1. 01

   Capture the actual game

   Use a frame capture tool such as PresentMon and export CSV. The browser test measures this page’s animation cadence; it cannot capture a separate desktop game.

2. 02

   Import and select the stream

   Choose the baseline CSV in the analyzer. If the file contains multiple applications or swap chains, select the game’s intended stream before reading the report.

3. 03

   Read the timeline

   Higher frame-time spikes mean longer intervals in this capture. Check when they occur and what happened in the scene. A low average frame time does not exclude occasional pauses.

4. 04

   Compare matching captures

   Add an after-change CSV and review average FPS, 1% low and the timeline together. Repeat runs before drawing conclusions; an imported file does not prove an optimizer caused the difference.
