Need help setting up a new laptop
​
Recently I've been dealing with a malware, everything's okay now, I restored it, not a problem anymore, but after I turned my laptop on for the first time after restoring it, it's not running games like it used to. For example, i used toplay zenless zone zero at 80-100 fps, but after restoring it, it's not only stuttering A LOT, but it's also running at barely 20 fps. I don't remember what I did to make it run smoothly, I just know that i used to play 100 fps while I had OBS, spotify, ds4, and god knows what at the same time and I've never felt this kind of stuttering before! I really wanna know what I've been doing wrong or what did I left out. I have an Acer Nitro V15-51. I've updated drivers, set up energy mode to performance, uninstalled third party softwares. I won't mind going through every single step again, I just want the performance I used to have. What should I do?
I'm having a really hard time trying to fix everything, but at the same time I don't wanna mess things up, I don't know what to do. I just factory reset everything cause I need to start over and re-do everything from the beginning, not skipping even a little "worthless" step
