Experiencing major frame rate isses

Got a GTX 3070, Ryzen 7, 165hz monitor, and 16gb of ram. I have updated my drivers, changed to full desktop, restarted the game, restarted my computer, closed everything in the background, and closed down all fps counter. When i press the window key though, the game runs perfectly in the background.

I start the game and frame rate is smooth for a couple seconds and then i’ll start seeing a slideshow. Please help. I dont have my graphics settings on ultra. They are between medium and high but i dont think its much to ask for to go with high settings if i have a 3070
