This article will provide you with several potential fixes for Diablo Immortal controller lag. All the solutions listed below have helped different players to eliminate the problem of their controller not working, but not all are guaranteed to work. 

Disconnect and Reconnect Your Controller

Sure, this is “capital T” Troubleshooting 101 stuff, but it’s worth trying out first. Some players also reported that simple re-plugging of the controller may help the issue as well. Here’s what you need to do aside from simply unplugging your controller and plugging it back in:

Exit Diablo Immortal. Close Blizzard launcher app. Plug out and plug in your controller. Start the launcher and the game using the controller.

Hopefully, the lag should be removed once the game properly initializes your controller.

Switch to Controller In-Game

Many players also forget about the in-game option of switching the game controls from mouse and keyboard to controller. You can make sure your settings are correct by following these steps:

Go to “Settings” menu. Select “Controller” feature. Switch to “Controller” option instead of “Keyboard”.

You may also need to restart your game for the new settings to take effect.

Disable Frame Limit Settings

One of the main reasons controllers lag in the PC version of Diablo Immortal is because the graphics settings limit your FPS count. To potentially remove the lag, try the following:

Go to “Settings” menu. Select “Graphics” feature. Choose “Uncapped” in the FPS section. Choose “Off” in the Vertical Sync section. Choose “Off” in the Image Sharpening section.

In addition to these settings, disable all third-party FPS programs that may be working on your PC and affecting the frame rate of Diablo Immortal.

Aside from these potential fixes, it’s always worth:

Checking battery levels for wireless controllers.   Checking that your drivers are up to date.   Checking that your USB port works.   Unplugging other USB-connected devices. Enabling Bluetooth if the controller supports it.  

Those are easy things to check. If all is seemingly lost, uninstalling and reinstalling controller software can potentially work, as well. 

Hopefully, your controller now works perfectly well in Diablo Immortal. If you are looking for a way to change resolution in Diablo Immortal, then click the provided link for the related guide.
