If you have already gone through the initial setup please skip to Step 11 for the Normal Usage Quick Guide.

Windows 11 users with the current version of the program will need to make sure the "Memory Integrity" setting is set to "Off" in the security settings. To access this option, search for "Core isolation" or find it under the Windows Security section. The first option in the window is "Memory Integrity."

Turn it off.

Download the program and extract the folder into a permanent location. This example uses the Desktop, but we recommend choosing a folder on the PC that you may not regularly delete, like the "Downloads" folder.

The folder contains a few README and other miscellaneous files. Ignore those for now, and open the "DRIVER" folder.

The "DRIVER" folder contains the program (Setup.exe), the drivers themselves, and the uninstall program. Open Setup.exe by double-clicking it.

Note: In some cases, you may need to right-click and select Run as Administrator instead.

A Windows prompt about an unknown publisher may appear. This is normal. Click through the prompts to open the program.

After successfully opening the program, make sure the controller is connected to the PC. Navigate to the "Devices" dropdown menu at the top-left of the window, then select "All."

Look for your controller in the list of devices. Unfortunately, the "Device Name" column may not be helpful, especially if you have a lot of USB devices. Look at the "Child Name(s)" column instead. The names in this column can be a little tricky, but a few words in, you should see "Wireless Controller" included on one of the lines. That's your controller.

Click on that device. When selected, the highlight color should change.

Next, find the "Selected Rate" drop-down menu at the bottom-left that currently reads "Default." Open the menu, select "1000," and click the "Install Service" button to finish.

If successful, you should see either a progress bar or a screen flash letting you know the program is flashing the driver. Once complete, the Polling Rate under the "Rate" column should now match your selection.

During the first installation and use of the driver, it's crucial to look out for any errors. They would likely have appeared at this point of the process. If so, find answers to common installation errors on the GitHub Wiki by clicking the button below.

A common Windows 11 fix is to right-click the "HIDUSBF_AS" file, then click "Install" to manually load it for the first time. Try this also with the "1kHz.cmd" file by right-clicking it and choosing "Run as Administrator." Those two steps resolved any issues we had.

Optional Quality-of-Life Step

This guide is not necessary for functionality and may be skipped.

Return to the main "DRIVER" folder that you previously unzipped and saved in a secure location.

Right-click "Setup.exe," then choose "Copy as path."

Go to your Desktop. Right-click and select "New," followed by "Shortcut."

Paste (CTRL+V or right-click and Paste) the file path copied in Step 2.

Click "Next" and give the shortcut a name. Click "Next" one final time to save the shortcut.

Only proceed after completing the initial setup.

The steps are similar to the initial setup but with some minor tweaks.

If the program is already open you may skip this step. If not:

Open the program (Setup.exe), either from the "DRIVER" folder or the desktop shortcut, if you made one.

Click the "Devices" drop-down at the top-left and select "All."

Find your controller in the device list and left-click it to select it.

Click the Checkbox next to "Filter on Device" at the bottom-left.

Select a new polling rate in the nearby "Selected Rate" drop-down menu. (1000Hz for PS4, and 1000-8000Hz for DualSense).

Click "Install Service."

Click "Restart" to disconnect and reconnect the controller.

Sometimes, system errors may require physically unplugging and replugging the controller instead.

If the overclock was successful, the "Filter" column should say "Yes," and the "Rate" column should match the new rate you selected. You should be able to unplug and replug the controller, and the Filter/Rate columns should continue to show the flashed rate afterwards.

For a final verification, click the "Devices" drop-down at the top-left and select "with HIDUSBF."

Your controller should show on that list.

• GPDL Fires a button press 2000 times and records the time it takes for the PC to register then averages those results.
