Quick Answer

FPS drops after a Windows update are almost always caused by driver conflicts, background telemetry processes, or power plan resets. Reverting the problematic driver, restoring your GPU power settings, and disabling unnecessary background services resolves the issue in the majority of cases without rolling back the entire Windows update.

Why Windows Updates Drop FPS

Windows updates frequently touch GPU driver stacks, DirectX components, and background services. When a cumulative update ships, it can overwrite a previously stable GPU driver with a newer version that contains bugs for your specific hardware configuration. Updates also reset power plans from High Performance back to Balanced, which throttles CPU and GPU clocks during gaming. A third common culprit is the Windows Update service itself, which continues running disk-intensive operations in the background for hours after the update completes, robbing your game of I/O bandwidth.

In 2026, several cumulative updates to Windows 11 24H2 caused FPS regressions specifically on NVIDIA RTX 40-series and AMD RX 7000-series cards by changing scheduler priority for GPU processes. SA gamers reported the drops predominantly in titles using DirectX 12 Agility SDK.

Step-by-Step Solutions

Start with the simplest fix: open Windows Settings, go to System, then Power, and set your Power Mode to Best Performance. Many FPS losses disappear at this step alone. Next, open Device Manager, locate your Display Adapter, right-click, and select Update Driver. Choose to browse your computer for drivers and roll back to the previous version if the option appears.

If the rollback option is greyed out, download the exact previous driver version directly from AMD or NVIDIA websites, then install it using the clean installation option. After installing, open Task Manager during a gaming session and check for any Windows processes consuming more than 5% CPU. Processes like SIH Client, Windows Update Orchestrator, and Compatibility Appraiser are frequent offenders. You can delay their execution via the Task Scheduler.

Finally, disable Xbox Game Bar if you do not use it. Post-update, Game Bar occasionally re-enables and adds overhead. Go to Settings, Gaming, Xbox Game Bar, and toggle it off.

Frequently Asked Questions

Will rolling back the Windows update fix FPS drops? Sometimes, but it is not always necessary. Driver rollbacks and power plan resets fix the majority of cases without touching the Windows update itself.

How long do background update processes run after a Windows update? Background indexing and compatibility checks can run for 2 to 4 hours after an update. Rebooting and waiting before gaming is advisable.

Does Windows 11 24H2 cause more FPS issues than previous versions? Several cumulative updates within 24H2 introduced GPU scheduler changes that affected certain card and driver combinations. Keeping GPU drivers manually managed rather than Windows-update-driven reduces exposure.
