Simulator suddenly unplayable due to stutters

Hello everyone, I’ve been having some problems with my simulator for multiple days now. Starting off, I had the black loading screen glitch and could not really do anything about it. I ended up reinstalling the sim which fixed that. I was very glad to see something different than just black on the screen, however the sim was basically impossible to navigate because of major stutters. These make clicking on anything virtually impossible because of how frequent and long they are (Every other second basically). I got really frustrated and decided to reset my whole computer. Starting the sim on the newly installed windows, and I get the same thing, with the sim being even more unstable (not responding for 10 mins. after dragging around the window). I’m don’t how this would be a software issue because of the fresh installation. I’m running a 3070 with a Ryzen 7 5800x so I couldn’t see how my hardware would be at fault. Graphic driver is up to date and I’ve pretty much tried every troubleshooting method on the forums. Any help is really appreciated!
