About AV Sync Latency:
This tool measures your reaction consistency between a visual flash and an audio pulse. While it relies on human reaction, the consistency (jitter) indicates how stable your system latencies are.
Hardware Buffer
Audio devices often have a "buffer" that delays sound. Modern gaming headsets aim for <20ms.
Input Lag
Monitor response time and peripheral polling also contribute to the total delta.
