Description

Description:
CaptureSlowFrame.jpg

Opens "capture frame" dialog if current frame exceeds set threshold in seconds. One can indicate to either capture duration of a specific profiling selection or the total duration of the frame. The selection names can be obtained by expanding the profiling tree. Clicking on a tree item will highlight the item on the graph and vice versa. The GUI also provides method of copying of the displayed data to clipboard. Some of the selections:

Render Main Thread Visualize Mjob
  • bgD3D
  • total
  • memAl
  • visul
  • Mjob
Chrome export format:

Capturing to file also creates a .trace file, which can be imported into chrome://tracing (in chromium based webbrowsers), or https://ui.perfetto.dev/
The same format can be exported by pressing the "COPY ALL" button, in the capture frame UI, with CTRL key being held down.

this is happening automatically now, right? so just part of the description and nothing parameter related

Syntax

Syntax:
diag_captureSlowFrame [section, threshold, frameSkip]
Parameters:
section: String - case-sensitive
threshold: Number - section duration in seconds. 0 captures always IF the section you gave as section filter appears inside the given frame. "total" always appears, while "callExt" might not always appear for example
since Arma 3 logo black.png1.18
frameSkip: Number - number of frames to ignore before measuring
since Arma 3 logo black.png2.20
toFile: Boolean - if true, doesn't open UI and writes straight to file. If logging to file, it automatically also outputs a .trace file. Note: even if false it might still force to file if it doesn't have a UI, like a server or HC
since Arma 3 logo black.png2.20
continuousCounter: Number - captures N slow frames. 0 or 1 will only capture one frame - don't set it to negative! Can be aborted by running diag_captureFrame or another captureSlowFrame
Return Value:
Nothing

Examples

Example 1:
diag_captureSlowFrame ["total", 0.003];
Example 2:
diag_captureSlowFrame ["memAl", 0.0001, 30];
Example 3:
diag_captureSlowFrame ["total", 0, 0, false, 3];
Will open the capture ui 3 times
