Updating the BIOS or UEFI firmware can improve hardware compatibility, fix security vulnerabilities, and add support for new features. However, in some cases users notice reduced laptop performance or lower FPS in games after a BIOS update. This can be frustrating, especially if the system previously performed well before the firmware upgrade.
Performance drops after a BIOS update may occur due to changed power management settings, modified CPU or GPU behavior, thermal limits, or reset BIOS configurations. Many BIOS updates reset important settings to their default values, which may affect performance-oriented configurations.
Fortunately, several adjustments can help restore your laptop’s performance and gaming frame rates. In this guide, we will walk you through the most effective ways to fix performance and FPS drops after a BIOS update.
How to Fix Laptop Performance and FPS Drop After BIOS Update
Follow the solutions below to restore normal system performance.
1. Load Optimized Defaults in BIOS
Sometimes BIOS settings may become unstable after an update. Resetting them can help.
- Restart your laptop.
- Enter the BIOS or UEFI setup during startup (commonly by pressing F2, Delete, Esc, or F10).
- Locate the option Load Optimized Defaults or Load Setup Defaults.
- Select the option and confirm the action.
- Save the changes and exit the BIOS.
This restores recommended hardware configurations.
2. Check CPU Power and Performance Settings
BIOS updates may change CPU power limits or performance modes.
- Restart your laptop and enter the BIOS/UEFI settings.
- Navigate to the Advanced, Performance, or CPU configuration section.
- Look for settings such as:
- Intel Turbo Boost / AMD Precision Boost
- Performance Mode
- CPU Power Limits
- Ensure performance features are enabled.
- Save the settings and exit BIOS.
Re-enabling these options allows the processor to operate at full performance.
3. Set Windows Power Plan to High Performance
A BIOS update may cause Windows to switch to a lower power profile.
- Press Windows + I to open the Settings app.
- Click System.
- Select Power & battery.
- Locate Power mode.
- Choose Best performance.
This allows the CPU and GPU to operate at higher performance levels.
4. Update Graphics Drivers
After a BIOS update, outdated or incompatible GPU drivers can affect performance.
- Right-click the Start button.
- Select Device Manager.
- Expand Display adapters.
- Right-click your graphics card.
- Select Update driver.
- Choose Search automatically for drivers.
- Restart your computer after installing updates.
You can also download the latest drivers from the NVIDIA, AMD, or Intel website.
5. Check Thermal Performance and Fan Settings
BIOS updates sometimes modify thermal profiles that limit CPU or GPU performance.
- Restart your laptop and enter the BIOS/UEFI setup.
- Locate the thermal management or fan control section.
- Set the system to Performance mode or Balanced mode instead of silent mode.
- Save the changes.
Improper thermal settings may cause the CPU or GPU to throttle.
6. Disable Virtualization-Based Security (If Enabled)
Some BIOS updates enable additional security features that can slightly reduce performance.
- Press Windows + I to open Settings.
- Click Privacy & security.
- Select Windows Security.
- Click Device security.
- Open Core isolation details.
- Disable Memory integrity if it is enabled.
- Restart your computer.
This may improve performance in certain gaming scenarios.
7. Update Chipset Drivers
Chipset drivers control communication between the CPU, motherboard, and other components.
- Visit your laptop manufacturer’s support website.
- Search for your laptop model.
- Download the latest chipset drivers.
- Install the drivers and restart your computer.
Updated chipset drivers ensure optimal hardware performance after a BIOS update.
8. Roll Back the BIOS (If the Issue Persists)
If performance issues started immediately after the BIOS update, rolling back may be necessary.
- Visit the manufacturer’s support website for your laptop.
- Check whether a previous BIOS version is available.
- Download the older BIOS firmware.
- Follow the manufacturer’s instructions to downgrade the BIOS.
- Restart the laptop after the rollback.
Rolling back the BIOS should only be done carefully, following official instructions.
Conclusion
A BIOS update can sometimes cause unexpected performance issues such as reduced FPS in games or slower system responsiveness. These problems are often related to changed BIOS settings, altered power management configurations, outdated drivers, or new security features.
By loading optimized BIOS defaults, enabling performance features, adjusting Windows power settings, updating graphics and chipset drivers, checking thermal settings, and disabling unnecessary security features, you can usually restore your laptop’s original performance. If the issue persists, rolling back the BIOS to a previous stable version may resolve the problem.
