Initially, try diagnosing the issue in the software section. I recommend restarting the game you wish to play, then attempt to reinstall your GPU driver. You can locate each driver on the official websites of AMD and NVIDIA. If this doesn’t work, consider resetting your operating system (possibly Windows 10). This is the last resort since the OS is too large and finding the main problem would require significant time. All the suggestions here are for the software approach; I advise against opening the PC case first, as it makes troubleshooting much harder before you examine the hardware.

It seems like you're trying to assess whether the CPU is limiting performance, particularly in CPU-heavy games like ARMA3. You also want to know if you use SSD or HDD, when your system was last reinstalled, how 'dirty' it is, and what the current CPU/GPU temperatures are.
