If [code]true[/code], flushes the standard output stream every time a line is printed. This affects both terminal logging and file logging.
When running a project, this setting must be enabled if you want logs to be collected by service managers such as systemd/journalctl. This setting is disabled by default on release builds, since flushing on every printed line will negatively affect performance if lots of lines are printed in a rapid succession. Also, if this setting is enabled, logged files will still be written successfully if the application crashes or is otherwise killed by the user (without being closed "normally").
[b]Note:[/b] Regardless of this setting, the standard error stream ([code]stderr[/code]) is always flushed when a line is printed to it.
+ Changes to this setting will only be applied upon restarting the application.
Debug build override for [member application/run/flush_stdout_on_print], as performance is less important during debugging.
+ Changes to this setting will only be applied upon restarting the application.
Forces a delay between frames in the main loop (in milliseconds). This may be useful if you plan to disable vertical synchronization.
