Hence, we’ll be showing you a list of steps to apply to fix low FPS after a CPU upgrade quickly.

What causes low FPS after a CPU upgrade?

The following are some of the causes of low FPS after CPU upgrade:

  • Incompatible Drivers – After upgrading your PC, you’ll need to download the appropriate set of drivers that are compatible with your OS. If you install drivers not compatible with the upgraded CPU, you’ll likely experience low FPS. 
  • CPU Bottleneck – Upgrading your PC can lead to a CPU bottleneck. This occurs when the CPU is not fast enough to process the amount of data used by the upgraded GPU. When this happens, your CPU will bottleneck your GPU and reduce performance. 
  • Outdated Graphic Drivers – If you just upgraded your PC, the drivers previously installed on the system would likely be outdated. Running games on outdated graphics drivers can lead to low FPS.
  • Game DVR – Game DVR is a part of the Xbox game bar used in recording video in the background while you game. It’s a very neat feature that gamers use to capture epic gaming moments. However, this feature can also cause low FPS after upgrading your CPU.

Irrespective of the causes, let’s explore the solutions below.
