DualSense support is relatively okay for gamers wanting to use the controller for PC games as opposed to a PS5, but up until now the only way to update the firmware on a DualSense has been through the console. PS5 owners should well know by now the pop-up screen asking them to plug their controller in via USB for the newest update (or in the case of those of us too lazy to get up and plug it in, the more familiar button that tells the console to ask again in 24 hours).
Thankfully, Sony has just released the “Firmware updater for DualSense wireless controller” app for Windows PCs, which allows users to do exactly what it says on the tin – update their DualSense controller’s firmware.
While nothing has been drastically altered with DualSense firmware updates to date, Sony strongly recommends keeping it up to date anyway:
Updates to the firmware will be released for your DualSense wireless controller from time to time which are necessary for the proper functioning of the controller. You will be notified about new firmware updates when you update your PS5 system software to a later version or when you launch the [Firmware updater for DualSense wireless controller] app. SIE strongly recommends always installing the latest update as soon as possible after the update is released. Failure to do so might expose your controller to security risks and/or might compromise the proper functioning of the controller.
