It’s crucial to note that while Bottlenecked’s calculator gives feedback faster than many other calculators, it often misbehaves, especially during the recalculating process.

– Neck Calculators

The Neck calculator is a bit unique. Use the procedure below to determine the bottleneck extend in your system:

  • Click to open the Neck Calculator
  • Select the specific components to check and specify the storage, GPU RAM, and CPU screen resolution. 
  • Press the submit button. 

This action redirects you to a different page, where you will only click the reveal button to see your results. The bottleneck results are displayed on the left side of the screen, and they cover the estimated percentage. Any other issues affecting your system are displayed on the right side. At the bottom of the screen, you will find a list of suggested components of your system. 

– GPU Check Comparison Tool

This online tool gives you more insights about a computer graphics card. Typically, it shows power resources along with other detailed options. Therefore, this tool is helpful when you want to determine the power of different GPUs, it can be beneficial on certain occasions. 

So, how do you use the GPU Comparison? 

  • Plugin your GPU and CPU model along with the desired graphics settings
  • Insert your desired GPU or CPU. This should be the component you wish to upgrade to.

Give the tool a few moments to generate a comprehensive report. Typically, the information will contain 12+ comparative benchmarks. Pay attention to the CPU impact on the FPS. The value should be less than 10 percent. The percentage ideally pinpoints if there is a GPU-CPU mismatch, which causes bottlenecks. Also, it tells whether upgrading any of the components will resolve the problem. 

– MSI Afterburner

The MSI Afterburner is an app that helps you directly monitor your GPU and CPU performance. The  Afterburner software is a free resource of MSI, meaning that anyone can use them to check bottlenecking issues. 

MSI Afterburner is a popular option for its reliability. In addition, it works with cards from all brands while giving you complete control. Remember, you can monitor your hardware in real-time.

Use this tool for all your GPU tuning needs, including underclocking, overclocking, undervolting, etc. Get the latest MSI Afterburner version at MSI’s website and run the installer. If you need older versions, get them at FileHorse.

It will give you two options during installation, MSI Afterburner or RivaTuner Statistics Server (RTSS), which is part of the installer. RTSS allows you to show statistics and frame rates overlaid during games. Follow the instructions to complete the installation.

What can you do with the MSI Afterburner? The Afterburner software shows your GPU stats (clock speed and temperature). You can click on the sliders at the bottom to gain deeper insights.

Start playing a game impacted by the bottleneck issues, and see what the software offers. Concentrate on CPU and GPU usage. For instance, if the game uses 30 percent of the GPU’s capacity and 80 percent of the CPU’s capacity, you can conclude that your CPU is the one causing the bottleneck. 

– Windows 8 Dual Performance Monitors

A pair of performance monitors in Windows 8 can help you determine which of your computer’s subsystems is facing bottlenecks. The quickest and easiest method to access it is via the inbuilt performance tab in the Task Manager. It looks and works much better than the one in Windows 7. 

Windows 8 Dual Performance Monitors

Here is how to access it:

  • Find and open the Task Manager. You can use the Ctrl + Alt + Del method, Ctrl + Shift + Esc, or press the Windows key and type Task Manager. 
  • Click on the Performance tab to display the performance of the GPU, CPU, RAM, and other hardware components.
