DPC Latency Checker

DPC Latency Checker is a tool that analyses the capabilities of a computer system to handle real-time data streams properly. It helps to find the cause for interruptions in real-time audio and video streams, also known as drop-outs. DPC Latency Checker tool determines the maximum DPC latency that occurs on your Windows system and thus enables you to check the real-time capabilities of your computer. DPC Latency Checker works independently of any external hardware. DPC Latency Checker periodically updates its internal statistical data at an interval displayed as Test Interval. This statistical data is queried and displayed on screen once per second. The Current Latency value indicates the maximum DPC latency measured within the last second. The value labeled Absolute Maximum represents the maximum latency measured since the tool was started. Use the Reset button to clear this value.
