ok im having the same issue, get a temp monitor like hwmonitor and run the game in windowed full-screen and set hwmonitor to be "always on top" and whlie playing look at your temps and report them to us. i believe that your cooler might be going a bit wonky making the system "thermal throttle"

note: if you can after that do the same with task manager on the performance

damn you komayy providing a better tutorial

Hi.

When playing games, hit ctrl+shift+esc and click on the performance tab, how much of your CPU or Ram is being used up?
Write that down. Now, go back to the 'Processes' tab and sort them by either CPU, or Disk usage by clicking on those buttons at the top, you'll see they have an overall percentage of how much they are being used on your PC.
