DPC Latency Checker 1.1.0

DPC Latency Checker is a free tool to keep track of how your system responds to the tasks it has to complete in real time. DPC stands for Deferred Procedure Call, a Windows function that allows high-priority jobs to delay low-priority jobs for later execution. For example, device drivers are high priority jobs that need to be carried out before other jobs.

If a device has a corrupted driver, this will take longer than usual to operate and will degrade system performance. In this article we will learn how to use the DPC Latency Checker to find out if you have a problem with a device driver, and how to fix it.

Note: DPC Latency Checker measures the response time on your system. Response time is affected by any application running on your system. For accurate results, we should disable all applications before starting the DPC Latency Checker. If you run this tool while having many applications open, you will receive a notification that, when you close them, the results will be improved.

Unfortunately, the DPC Latency Checker only shows if there is a problem with a device's driver, not necessarily the driver that is causing the problem you're facing. You will have to manually disable and then re- enable a device driver from Device Manager . Be sure to carefully read the DPC Latency Checker instructions about which drivers you should disable first and which drivers you should not disable .

If you know any other tools that can help fix drivers, don't forget to include them in the comments.
