How can I prevent the preview window from lagging my videos?

I was using OBS for a while and everything was fine until one day it wasn't. It was lagging like crazy and I didn't know why. I did everything like changing settings, disabling game mode and more, but it didn't fix it. For some reason, removing the preview window removed all sort of lag on my videos. Why, I don't know. I'm on Windows 11 and have a beefy gaming pc.

AMD Ryzen 9 5900X
Asus Rog Strix RTX 3090
32GB Dominator Platinum Ram
Asus Rog Crosshair VIII Dark Hero motherboard

As you can see, my pc is powerful and shouldn't be experiencing lag like this. What can I do to fix this problem?
