DPC Latency Checker

DPC Latency Checker is a tiny and portable application that monitors computer activity and verifies if it is able to handle real-time streaming of audio and video data without interruptions. It does not include configuration parameters.

Since installation is not a prerequisite, you can drop the executable file anywhere on the hard disk and click it to run.

It is also possible to move DPC Latency Checker to a USB flash drive or similar storage unit, in order to use it on any machine with minimum effort.

An important aspect to keep in mind is that the Windows registry does not get new entries, and files are not left behind on the hard disk after program removal.

The interface of DPC Latency Checker is based on a standard window that contains a graph which tracks DPC latency. You can view the test interval, current latency, and absolute maximum value. Aside from stopping the monitoring process, you can reset the numerical values. There are no other options available through this tool. For example, you cannot ask DPC Latency Checker to record activity to file.

The simple application does not put a strain on system resources, as it requires a low amount of CPU and RAM to run properly. No error dialogs were shown in our tests, and the tool did not hang or crash. To conclude, DPC Latency Checker offers a straightforward solution to diagnosing computer latency issues with minimum effort.
