8. Disable Safe Mode: Press Windows key + R, type “msconfig”, go to the Boot tab, uncheck “Safe boot”, click Apply and restart normally

Why This Works

DDU removes all traces of previous driver installations, including:

• Registry keys that may contain corrupted configuration data
• Cached shader files that might be incompatible
• Service entries that could cause conflicts
• Leftover DLL files from incomplete uninstallations

This creates a “clean slate” for the new driver installation, eliminating any potential conflicts that might prevent driver 581.94 from functioning properly.

Method 4: Disable Hardware-Accelerated GPU Scheduling

Frequently Asked Questions

Will uninstalling KB5066835 expose my system to security risks?

While KB5066835 includes security patches, the immediate risk of uninstalling it is relatively low for most home users, especially if you’re running updated antivirus software and practicing safe browsing habits. However, it’s not a permanent solution—you should reinstall the update once Microsoft releases a fix for the GPU performance issue. The better long-term approach is using Nvidia driver 581.94, which resolves the performance problem without requiring you to remove security updates.

Does driver 581.94 work with all Nvidia GPUs?

Driver 581.94 officially supports Nvidia GeForce RTX 40-series and 50-series GPUs. For older RTX 30-series, GTX 16-series, and GTX 10-series cards, compatibility varies. Check Nvidia’s official driver release notes for your specific GPU model. If your card isn’t supported by 581.94, your best option is uninstalling the problematic Windows update or disabling hardware-accelerated GPU scheduling until a compatible driver is released.

Why is my GPU showing 99% usage but still getting low FPS?

This is a hallmark symptom of the KB5066835 bug. The Windows update forces your GPU to operate at significantly reduced power levels (approximately 100W less than normal), even while reporting high usage percentages. The GPU is technically working at full capacity for the limited power it’s being allowed to draw, but that capacity is artificially restricted. Installing driver 581.94 or removing KB5066835 allows your GPU to draw proper power and deliver expected performance.

I installed driver 581.94 but still have performance issues. What should I do?

If driver 581.94 alone doesn’t resolve the issue, follow these steps in order: (1) Use DDU to perform a complete driver cleanup and reinstall 581.94 from scratch, (2) Check if multiple problematic updates are installed (KB5074109 or KB5077181) and remove them, (3) Disable hardware-accelerated GPU scheduling in Windows settings, (4) Verify your power plan is set to “High performance” in Control Panel. If issues persist after all these steps, check if your specific game has known issues with Windows 11 24H2/25H2 independent of the Nvidia problem.

How do I know if the fix worked?

You’ll know the fix was successful when you observe: (1) Frame rates returning to pre-update levels in your games, (2) GPU power consumption returning to normal ranges (check with MSI Afterburner or GPU-Z—should be 300-400W+ under load for high-end cards), (3) Elimination of stuttering and frame pacing issues, (4) GPU usage percentages that fluctuate naturally with game demands rather than staying locked at 99%. Benchmark your system before and after applying fixes using tools like 3DMark or built-in game benchmarks to objectively measure the improvement.

Should I install newer Nvidia drivers when they’re released, or stick with 581.94?

Nvidia driver 581.94 is specifically designed to work around the Windows 11 KB5066835 issue. Future driver releases (582.xx and beyond) will likely incorporate this fix while also adding support for new games and performance optimizations. When new drivers are released, check the release notes to confirm they address the Windows 11 24H2/25H2 performance issue before updating. As a general rule, if 581.94 is working perfectly for you, you can wait 1-2 weeks after a new driver release to see if early adopters report any problems before updating.
