Massive game FPS drop after installing Win10 update KB5065429 when using XBOX wireless controller

Addressing FPS Drop Issues Post-Windows 10 Update KB5065429 When Using Xbox Wireless Controllers

Recent updates to Windows 10 can sometimes introduce unforeseen compatibility and performance issues. One such concern has emerged following the installation of update KB5065429, which appears to significantly impact gaming performance when using Xbox wireless controllers. This article delves into the problem, explores potential workarounds, and discusses effective solutions to restore optimal gameplay.


The Issue: FPS Decline Linked to Windows Update KB5065429

Users have reported a notable decrease in frame rates during gameplay — from over 100 FPS down to single digits — specifically when utilizing a wireless Xbox controller connected via the official Microsoft Xbox Wireless Adapter. This problem is exacerbated over time, rendering games nearly unplayable.

Key points include:
– The issue began immediately after installing update KB5065429.
– Both Microsoft’s official wireless adapter and third-party controllers such as the Gamesir Xiaoji G7 Pro are affected.
– The problem persists regardless of the controller’s charge status, as tested with fully charged batteries.


Temporary Workaround: Disconnect and Reconnect

A provisional solution involves disconnecting the wireless controller:
– Hold down the Xbox button on the controller until it powers off.
– Reconnect the controller to restore gameplay temporarily.

However, this fix is short-lived, as the FPS drops tend to reoccur after a few minutes of gameplay when reconnecting the controller.


Recommended Permanent Solutions

For a more durable fix, consider the following options:

1. Switch to a Wired Controller

Using a wired Xbox controller bypasses wireless connectivity issues altogether, ensuring stable performance without additional configuration.

2. Uninstall or Roll Back the Problematic Windows Update

If you prefer to maintain the current hardware setup, uninstalling or rolling back the specific update can resolve the problem:
Uninstall KB5065429 directly via Windows Update history.
– Alternatively, uninstall KB5066198, as some users have noted this is a prerequisite for seeing KB5065429.
– To prevent the update from reinstalling automatically, consider pausing Windows updates through Group Policy Editor or other update management tools.


Additional Troubleshooting Measures & Insights

While some sources suggest solutions such as upgrading Bluetooth drivers or fully charging controllers, these do not seem applicable in this particular case. The affected user confirms their controller’s battery is fully charged, indicating power issues are unlikely.
