Do you have any other application processing input like Discord or some other browser window playing video ? If so, try closing those.

I do all that but it has no changes I was wondering if it was like a file problem or I have installed something i shouldn't have

How do you mean "file problem" ?

Tell me what you installed, and maybe I can tell you if it affects your problem.

just games and normal apps

There are lots of different types of 'normal apps'. A bittorrent app is a massive sharing networking app. A video editing app is a heavy cpu gpu app. you have to classify in more detail. Incidentally these 2 kinds of apps when run in the background will kill performance.

do you know any fixes??

Well the 'fixes' are more of eveything. More powerful CPU, GPU. Faster RAM, faster network. Since everything is in limited supply, stop using power hungry apps. Know your limits.
