The post critiques common methods — single-frame measurement and fixed N-frame windows — explaining why they produce misleading results. It recommends using a rolling time-based window (e.g., 1 second) to count frame completions, analogous to real-time monitoring in web services. Five methods are presented with pseudocode, from naive to robust, including tracking per-frame processing times within the rolling window. Practical tips cover using high-precision timers (SDL_GetPerformanceCounter, std::chrono::high_resolution_clock) and circular buffers as a memory-efficient alternative to queues. ## Full article daily.dev links to this article rather than hosting it.
