However, some users might experience a drop in FPS after a GPU upgrade, defeating the purpose of upgrading. This article will discuss the causes of low fps and provide steps to fix the error. 

What causes low FPS after your GPU upgrade?

If you’re currently experiencing low FPS after a GPU upgrade, here are some of the reasons causing the problem:

Missing drivers – When installing a new operating system, you must install all the drivers needed to run the PC. If your PC still has missing driver components, you will likely experience an FPS drop after a GPU upgrade. Insufficient RAM – Besides having a killer GPU, games require a minimum RAM to help run the game efficiently. Modern games need at least 16GB of RAM to run efficiently without any performance drop.  Poor cooling systems – Heavy-duty tasks like rendering and gaming use up a lot of resources and often increase the average temperature of the PC. In the absence of a sound cooling system, the CPU will overload, leading to CPU throttling.  External power – Some sets of graphics cards require an external power source to function optimally. If the graphics card doesn’t receive enough power from the cable connector, it automatically lowers your clock speed to prevent hardware problems. 

How can I fix low FPS after GPU upgrade?

Before we attempt the troubleshooting techniques, here are a few quick fixes you can test out to see if they resolve your issues:

Ensure the graphics card is plugged in if it has an external power source. Purchase a decent cooling system. Restart your PC.

If those quick fixes couldn’t resolve your error, attempt the following advanced troubleshooting techniques:

1. Uninstall the Display drivers

If you’re upgrading your GPU, you need to eradicate all old display adapters from your PC. Having new and old drivers operating in the same system could lead to errors like low FPS after a GPU upgrade.

2. Update Windows OS

A computer that runs outdated software is likely to experience bugs and errors. Keeping your PC updated helps keep your PC error-free.  Disclaimer: this program needs to be upgraded from the free version in order to perform some specific actions. However, some users can trigger the Windows Update not working error while updating their computers. Do well to read our guide on how to resolve it. 

3. Disable the Integrated graphics card from the BIOS

The integrated graphics card ships with most Windows PCs. It is suitable for average computing but not for users who undertake resource-hogging activities like gaming.   If you upgrade your GPU and the integrated graphics card remains enabled, it can cause low FPS due to conflicting resources among both software.

4. Reinstall the GPU drivers

In most cases, users are unsure of which drivers to download specifically. Manufacturers like Intel and AMD have an option on the download page that allows the website to determine the drivers compatible with your system. A drop in FPS after upgrading your GPU can be very frustrating as it entirely defeats the purpose of the GPU upgrade. Luckily, with the steps above, you can rid your PC of this problem.
