This article introduces how to fix the high DPC delay on Windows 10. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

Deferred procedure call (DPC) is a Microsoft Windows operating system mechanism that allows high-priority tasks to defer required but lower-priority tasks for later execution. This allows device drivers and other low-level event consumers to quickly execute high-priority portions of their processing and schedule non-critical additional processing to be executed at a lower priority.

High DPC latency is usually observed in device drivers, which sometimes make errors and display high DPC latency values. There are several solutions to this problem, some of which we will introduce below. Good luck!

Solution 1: change the current power plan

Almost all the power options you are changing are reflected in the balanced power settings, and even if one of the settings is not good, it will always reflect the performance of your computer. Several users claim that switching to high performance or power savings will help them solve the problem.

-right-click the battery icon in the system tray, and then click Power options. If you are not using windows10, click the start menu and search for Control Panel. Change the View by option to Large icons, then click the Power Options button.

Select any power plan except the balanced power plan by clicking the small circle next to the entry. You can also click Show other plans to view all the plans that you can choose from. Check to see if the problem is resolved.

Solution 2: disable dynamic tick and update the graphics card driver

This set of steps is primarily used to optimize and reduce "normal"-induced DPC latency by disabling dynamic ticking and updating graphics cards that are always associated with delays and delays. This step is very useful. If you find some problems, you can easily restore the * * section:

Search the start menu or the search bar next to it for the Command prompt, right-click it, and select the run as Administrator option. You can also use Windows Key + R to display the run dialog box. Type "cmd" in the box, and then order

Click "OK"

Copy and paste the following command, and make sure you click Enter later.

Bcdedit / set disabledynamictick Yes

You should see the message that the operation has completed successfully. Exit the command prompt and check to see if the problem is resolved. If not, continue with the rest of the solution.

It is time to update the video driver to try to reduce the DPC latency on your computer.

Select the start button, type device Manager, and then select it from the results list at the top. You can also use Windows Key + R to display the run dialog box. Type devmgmt.msc in the box, and then click OK.

Expand one of the categories to find the name of the device you want to update, then right-click it and select Update driver. For graphics cards, expand the display Adapter category, right-click the graphics card, and then select Update driver.

-- Select the driver software that automatically searches for updates.

If Windows cannot find a new driver, you can try to find it on the device manufacturer's website and follow its instructions. You need to repeat the same process for all graphics cards (integrated and external), or you can use automation tools to do this for you.

Solution 3: tamper with network equipment (wireless and Ethernet)

This method is useful and involves changing some settings in the device Manager of a computer network device. General purpose, these devices are the most common cause of high DPC latency on Windows PC, and it is always a good idea to try to change these settings to reduce latency.

Select the start button, type device Manager, and then select it from the list of results at the top. You can also use Windows Key + R to display the run dialog box. Type devmgmt.msc in the box, and then click OK.

Expand the network adapter category by clicking the arrow next to it, and then locate the wireless and Ethernet adapters. They should be at the top of the list with brand names, such as Intel.

Right-click each and choose Properties from the context menu. Navigate to the Advanced tab and you should be able to see the properties that list brands. Locate the Energy Efficient Ethernet option and disable it by clicking the option under Value and selecting Off.

After that, be sure to navigate to the Power Management tab, and then uncheck the box next to allow your computer to turn off this device to save power. Be sure to repeat this process for all appropriate devices and apply the changes. Check to see if the delay returns to normal.

This is enough about how to fix the high DPC latency on Windows 10. I hope the above content can be of some help and learn more. If you think the article is good, you can share it for more people to see.
