Function Documentation

app_metrics_log_gpu_stats()

bool app_metrics_log_gpu_stats	(	GPUProfiler *	profiler,
		double	current_time,
		bool	should_log
	)

Logs GPU performance statistics if the reporting window for any stage has elapsed.

This function handles the logic of checking sampling windows, calculating missed frames, formatting the output string, and logging the results via the logging system. It also resets samplers after reporting.

Parameters

profiler	Pointer to the GPUProfiler containing the stages and samplers.
current_time	The current application time (e.g. from glfwGetTime()).
should_log	If true, force printing even if interval not elapsed.

Returns

true if logs were printed (2s interval elapsed), false otherwise.
