In case your PC doesn’t ship the specified efficiency in a specific recreation, it’s normally—however not at all times—because of two limiting elements. Both your processor (CPU) or your graphics card (GPU) is bottlenecking efficiency.
How are you going to discover out which of those two important {hardware} parts is slowing down your gaming efficiency? This information will clarify the whole lot it’s worthwhile to know. However first, it’s worthwhile to perceive what a CPU bottleneck or GPU bottleneck really is, and what it means on your system.

What’s a CPU bottleneck?
A CPU bottleneck happens when your graphics card works quicker than the CPU. You may let you know’re encountering a CPU bottleneck when your GPU isn’t totally utilized. (The utilization of the CPU is irrelevant.)
In case your processor’s efficiency isn’t adequate to maintain tempo along with your recreation, this will result in a slowdown as a result of the graphics card can’t be totally unleashed. That’s a CPU bottleneck.
What’s a GPU bottleneck?
Conversely, a GPU bottleneck happens when your graphics card can’t sustain with CPU’s output.
When your GPU is bottlenecked, the graphics card can calculate fewer photographs per second than the CPU was capable of put together beforehand. The system is subsequently unable to appreciate its full gaming potential. In these instances, you’ll in all probability must improve to a brand new graphics card to eke out extra efficiency.
How do know in case your video games are CPU or GPU bottlenecked?
A CPU bottleneck occurs when the graphics card does its work in such a short while that it has to attend for the processor to offer the suitable knowledge for the following picture to be rendered. In these instances, the graphics card, regardless of how briskly it’s, can’t be utilized to its full capability.
However how precisely can you discover out if there’s a CPU bottleneck? Proceed as follows:
- Obtain and set up MSI Afterburner.
- In Afterburners settings choices, activate the GPU load choice for the overlay.
- Begin the sport you wish to play.
- Take note of the GPU utilization fee on Afterburner’s overlay when you play. It’s necessary that you simply learn the GPU load throughout a typical recreation scene. The values within the menu or when paused aren’t significant.

You need to use the GPU load data to find out whether or not there’s a CPU or GPU bottleneck within the recreation you’re testing:
≥ 95 p.c: GPU restrict = The graphics card limits the efficiency
< 95 p.c: CPU restrict = The processor limits the efficiency
In case your graphics card is utilized between 95 and 100%, the processor is robust sufficient and provides the GPU sufficiently. If the GPU is used 80 p.c or much less, meaning you’re hitting a robust CPU bottleneck.
Your gaming PC has a bottleneck. What must you do?
Should you discover that your processor is bottlenecking your gaming efficiency, you need to select a better decision if doable. Shifting to a better decision (like 1440p or 4K) places extra deal with the GPU, in case your graphics card and monitor are as much as the duty. If that doesn’t work, chances are you’ll must improve your CPU.
Should you discover that graphics card bottlenecking efficiency, attempt decreasing the graphics high quality presets within the recreation first, or at the very least decreasing extra strenuous graphics results (like ray tracing or texture high quality). Activating picture upscaling options like Nvidia’s DLSS, AMD’s FSR, and Intel’s XeSS must also assist, as they render frames at a decrease, extra GPU-friendly decision earlier than utilizing software program to upscale the picture again to your monitor’s decision. If that doesn’t work, you too can attempt decreasing your decision (e.g. from 1440p to 1080p).
Within the case of a extreme GPU bottleneck, chances are you’ll must improve to a extra highly effective graphics card.
