How do you test for bottlenecking?
There are several online bottleneck calculators that you can use to figure out what's holding your machine back. One option is CPU Agent's FPS and Bottleneck Calculator for this example. It's a simple process; head to the site, enter your CPU, GPU, and RAM information, then hit the Calculate FPS and Bottleneck button.
RAM isn't usually a bottleneck when gaming, unless you don't have enough. For most modern games, 8GB of RAM is a good baseline, though 16GB is quickly becoming the standard.
- Optimizing the cache usage, proper memory usage, adding more physical memory or re-evaluating the applications and processes.
- Monitoring the applications and correcting or replacing those that leak or use the memory inefficiently.
If your CPU usage is much higher than your GPU usage, that indicates a CPU bottleneck, and vice versa. Anything below 50% utilization is considered low, 50% to 70% is normal, and 70% and up is high.
PC bottleneck is a situation where one computer component hits its limit and limits the capacity of the other components in the system. If your favorite video game lags due to an underperforming video card, your processor's efficiency won't matter. The graphics are limiting your PC.
Most of the time, 32GB of RAM is more than you need, but this isn't always the case. There are times when 32GB is the right amount to have. It's also a good way to make sure your PC can keep up with changing needs as time goes on.
32GB of RAM is considered high and is generally overkill for most users. For most everyday use and basic tasks such as web browsing, email, and basic office work, 8GB of RAM is more than enough. Even for gaming or video editing, 16GB is typically sufficient.
Adding too much RAM will eventually jeopardize the computer's performance, even when you have enough of it. The additional RAM will start applying the law of diminishing returns at a certain point, meaning you won't get much value from it.
A RAM bottleneck can occur when the amount of RAM on a system is insufficient to support the GPU's ability to render data. In this case, the GPU will have to constantly swap data in and out of RAM, which can slow down performance.
Inspect your router's firewall settings to see whether they might be causing a performance bottleneck. You can check these settings through the router's control panel software on your computer, usually by typing the IP address “192.168. 1.1” (without quotes) into your browser's address bar.
How do I know if my RAM is bottlenecking my GPU?
If your CPU or GPU utilisation is maxed out while the other component has lots of headroom, the component that's maxed out is bottlenecking. To see whether your RAM is bottlenecking, check its utilisation in the Task Manager while gaming. If it's maxed out, you have a RAM bottleneck.
If the CPU usage is high while the GPU usage is low, you have a CPU bottleneck and the game is processor dependent. Vice versa, if it has a high usage of graphics card while low usage of central processing unit, you have a GPU bottleneck and the game is graphics card dependent.
