Understanding CPU Utilization

The CPU, on the other hand, handles game logic, AI, and processing tasks that aren’t related to rendering. If your CPU usage is low while experiencing low FPS, it could mean that either the tasks it’s managing aren’t demanding, or that another component is holding back the CPU’s full potential.

Common Reasons for Low FPS Despite Low GPU and CPU Usage

Bottlenecking Issues

One of the most common reasons for this problem is a bottleneck between your CPU and GPU. This occurs when one component is significantly stronger than the other. For example, if you have a powerful GPU but a weaker CPU, the CPU could be limiting how much data the GPU can process, causing low FPS despite low GPU usage.

Game Optimization Problems

Some games are poorly optimized for certain hardware configurations. Even if your hardware is capable, the game might not be designed to fully utilize your GPU or CPU. This results in lower performance, even though the components aren’t running at full capacity.

Power Management Settings

Your system’s power management settings might limit the performance of your CPU or GPU. For example, if you’re running on a power-saving mode, your computer could be throttling your hardware to save energy, which can drastically affect your FPS.

Sometimes, background tasks can hog your CPU or GPU resources without you noticing. Ensure there aren’t any unnecessary processes running in the background, such as system updates or heavy applications, that could be reducing your available power.

Updating Drivers

Ensure that your GPU and CPU drivers are updated. Sometimes low performance is caused by outdated or corrupt drivers, so keeping them up-to-date can resolve unexpected performance issues.

Advanced Troubleshooting Methods

BIOS and Overclocking Adjustments

If you’re comfortable with more technical solutions, adjusting BIOS settings or even overclocking your hardware can help unlock more performance. Overclocking increases the clock speed of your CPU or GPU, allowing them to work faster but with the risk of higher temperatures.
