To detect ingame your load / temp of your hardware we all have the possibility to install and run a tool in the background to show while gaming many stats of your hardware. This tool is very common by pc tech channels on youtube.
It is absolutely free to use. Many of you may know it, some of you eventually not.

This tool is needed to detect called "bottlenecks". As a very rough example, a bottleneck in games is created by a processor (cpu) or graphics card (gpu).

As example of a bottleneck system. The cpu is the bottleneck:
Intel Core i3 4340 (2 cores / 4 threads)
Nvidia RTX 3080

Chances are very high (depends also on game / resolution / ingame graphics settings) that you can not using its FULL potential of this fast gpu in combination with this slow cpu. You may see this ingame:

GPU load 50%
CPU load 100%
FPS: 65

===========

As example a balanced system:
AMD Ryzen 5 5600X (6 cores / 12 threads)
Nvidia RTX 3080

You may see this ingame:
GPU load 100%
CPU load 15%
FPS: 98


Thread is created for you who have problems with your PC and you do not know why the fps is dropping that high. Msi Afterburner give you a idea which parts slow down other parts.
Msi Afterburner is for all Systems. Intel, AMD, Nvidia.
