7800X3D + 4070 Super - Fortnite Chapter 5 1440p DX12 Low

Have been going through a couple of retestings for the past week and I found out that the Twitch tab, regardless if the stream is playing or not, hogs a lot of GPU usage, resulting to a chunky loss of FPS. I'll also have the Perf mode run after the last update.
If you didn't noe yet, I try to do realistic bench runs like having some apps opened in the background such as Discord, OBS, and a browser. I was mostly surprised because the difference was big compared to when I was playing with the 4070 Ti. Is it because of Windows 11? GPU scheduling? The single NVENC encoder? Driver version? So many variables that I don't really want to get too into but are important details to take into account
