Script Profiling

Script Profiling allows to profile script performance while it is running.

In-Game Profiler

Enable the in-game profiler from the Diag Menu > Statistics > Script Profiler - the value can be set to frame or continuous.

Memory Allocation

It is possible to dump all allocations from script:

• Run the game with the -checkInstance startup parameter
• Call the following from script: DumpInstances(/* bool csvFormatting = */ true);
• This outputs memory allocations in the logs to the CSV format Show example
