PC is more responsive after 4 am.

Long time lurker here. Want to share something that used to happen long time ago when I was battling with floaty mouse and microstutters in CS. Couldn't figure out back then and noticed the same thing this week again. I still have microstuttery gameplay at high fps, no matter what I do my game doesn't run smooth, 200+ fps feels choppy like I'm playing on 60hz. Even my mouse on desktop is like it's cursor trail is on, stuttering. Last 3-4 days I stayed up until 5 am and every time after 4 am my PC starts running properly on it's own. Game runs smooth, responsive, mouse is not floaty, even on desktop it feels like my monitor became 240 or 360 instead of 144. No stutters or trails when I move my mouse around.

I have optimized BIOS and using a fresh installed (5 days ago) W11 23H2, so I don't have any scheduled tasks in the background during day. Windows update is disabled. I'm convinced the problem isn't my setup or settings anymore. It's either network or electricity. I also notice my mouse becoming responsive when I disable the network adapter.

Specs: 7800x3d, RTX 3060, Asus TUF B650M+, Razer Viper V3 pro, network adapter is realtek 2.5gb
