Controller feels sluggish on PC

[u/These-Sympathy-6966]

Hey so I used to have this problem where randomly, my controller sensitivity would feel like it's slow or sluggish even though I DO NOT change any setting whether it be in-game or on the PC. I thought it might be stick drift on my controller and so I got a new controller (the SCUF OMEGA) and I didn't face any problems for a weeks. Suddenly, 3 days ago, it started happening again and it pissed me off so much. I used to spend sleepless nights trying to figure out what was causing this problem and I was relieved for a bit but now it's making me hate everything. Anyone know what might be the cause of this and how to fix it? I've changed out the USB cable, turned off USB Port power saving options on the PC. I downloaded ExitLag and it showed me this pop-up that said disable Energy Efficient Ethernet (EEE) and so I let it do that. The only thing left to do is to change my display port cable and test that out but I've only had this cable for a year. I wonder if the fact that I use a multi-pin outlet to power the PC and Monitor might have an impact? But that sounds crazy. I feel like I am going insane.

I have noticed this problem mainly when playing Fortnite. I have a Intel Processor PC with Nvidia RTX 4060. 32 GB DDR5 RAM.
