Working hard to save up money and after a long time of waiting and finally owning your own custom PC just to see your PC not able to deliver the frame rate it capable to provide.
I am not an expert on this topic but after seeing this issue I decided to do some of my own research and fix this issue so you can close this window and carry on with your gaming.There are some basic things to do If you find yourself with underperforming GPU. If you already have cane acrossed it then skip the below part.
- Switch the power management into Maximum Performance from Nvidia’s control panel [If you own Nvidia GPU]
- Download and install the latest chipset drivers
- Upgrade your Windows
1. CPU Bottleneck
Long story short, CPU bottleneck occurs when you pair a much powerful GPU with a low end CPU. Due to this the GPU cannot deliver frame rate up to its potential as the CPU is not powerful enough to handle it, further leading to low usage of GPU.
In this situation, doing a CPU overclock is the best option. For example if you have a AMD Ryzen 7 7100, which you can safely overclock up to 3.8Ghz from base 3.2Ghz. This may increase your performance up to 15-20% on average.
It’s important to know that the boost in performance level depends on how powerful your CPU and GPU is , if your GPU is too much for the CPU to endure then I hate it to break it down, ITS TIME FOR AN UPGRADE.
Do not overclock above recommended range to avoid damage to PC Parts:Risks
Every company provides a particular range limit for overclocking CPU which ofcourse will vary from company to company.
The CPU starts consuming mire voltage upon overclocking which generates more heat which can damage the CPU and devoid the warranty if you overclock it beyond the safe limit.
Just be sure that the reasons why your GPU is underperforming can depend on the age, other corresponding parts of your PC.
2. Ram Bottleneck indirectly causing low GPU usage
If some cases the low GPU usage can be related type of channel i.e if you are using single channel RAM system [which don’t recommend] then most of the times it will only be able to get half the Bandwidth of the Dual channel which in-turn pulls the performance level of CPU. Hence the CPU not keeping up with GPU to provide more FPS
You also need to check whether you playing on extremely high RAM frequency, this may also hold your CPU’s performance.
