Performance Profiling

Versions with performance profiling

• 98699
• 98711
• 98809

These beta builds contain performance tools normally not available for a retail version. These builds will be a bit slower as a result, and is therefore not intended for a general use.

Scripting commands

• diag_captureFrame
• diag_captureSlowFrame
• diag_logSlowFrame

How to use

1. Run a mission
2. Execute a scripted command diag_captureSlowFrame ['total',0.3] using any means (DevCon, mission radio trigger...)
3. Once a slow frame is detected, a window will open.
4. In the window you will be able to browse a lot of interesting performance information, which can be interesting.
5. But the main thing you should do so that I can see the information as well is:
   1. Select Main Thread (if not selected yet)
   2. Press Copy button
   3. Open an external text editor
   4. Paste the text into a new file
   5. Save the file

Notes

• 0.3 is a time in second used to determine what duration of a frame you consider abnormal, and first such frame will be captured.
• 0.3 is definitely something you should not see in a normal game.
• If you do not capture any frames with 0.3, try lowering it to 0.2 or 0.1.
• If it triggers too early, before the main slowdown happens, increase it to a higher value, e.g. 1.0.
