High GPU Usage, Low Game Performance: Unraveling the PC Puzzle


Why might my PC, which typically runs at 200 fps, suddenly drop to 40 fps in games, requiring over ten restarts to function properly? Despite enabling hardware-accelerated GPU scheduling, my GPU usage skyrockets to 97-100% without improving performance. I suspect the power supply might be inadequate, even though changing the power cord didn’t resolve the issue. My system includes a Ryzen 5 2600, GTX 1650, and a Kolink 600W 80+ PSU. What could be causing this problem?”


When a PC that normally operates at 200 frames per second (fps) in games suddenly drops to 40 fps, it’s a clear sign that something is amiss. This issue is particularly perplexing when it necessitates multiple restarts to restore proper function. The situation described also involves the GPU (Graphics Processing Unit) usage spiking to 97-100% when hardware-accelerated GPU scheduling is turned on, yet this does not translate to improved performance.

Potential Causes

1. Power Supply Issues:

While the suspicion might fall on an inadequate power supply, a Kolink 600W 80+ PSU should generally be sufficient for a system with a Ryzen 5 2600 and GTX 1650. However, if the PSU is failing or not delivering consistent power, it could cause the system to underperform.



Another common cause of reduced performance is overheating. If the CPU or GPU overheats, it will throttle performance to reduce temperature, leading to lower fps.


Software Conflicts:

Software issues such as driver conflicts, outdated drivers, or even background processes consuming too many resources can also lead to a drop in performance.


Hardware Accelerated GPU Scheduling:

While this feature is designed to improve performance, it may have the opposite effect if there’s a compatibility issue with the drivers or the game itself.


Malware or Virus:

A less common but possible cause could be malware or a virus that is using system resources, thus affecting gaming performance.

Troubleshooting Steps

1. Check for Overheating:

  • Monitor the temperatures of your CPU and GPU during gameplay.
  • Ensure your cooling system is working correctly.
  • 2.

Update Drivers:

  • Make sure all drivers, especially the GPU driver, are up to date.
  • 3.


spect Power Supply:

  • Test the PSU with a power supply tester or try a different PSU if possible.
  • 4.

Scan for Malware:

  • Run a full system scan with a reputable antivirus program.
  • 5.

Reinstall Windows:

  • If all else fails, a fresh installation of Windows can eliminate any software-related issues.
  • In

conclusion, the problem could stem from a variety of sources, and it may require a process of elimination to pinpoint the exact cause. It’s recommended to start with the simplest solutions, such as updating drivers and scanning for malware, before moving on to more complex troubleshooting like replacing the PSU or reinstalling the operating system. If the issue persists, consulting with a professional technician may be the best course of action.
