Huge pc performance issues after update?

So idk what’s going on I was getting a stable 60 fps with everything on cinematic and ray tracing on. I took a break from the game and booted it up today and now my games dropping from 60 to 40 to 20 to 80 constantly fps is ALL OVER THE PLACE. I even moved everything to ultra and removed ray tracing to see what the difference was and it’s the same thing.
