Game is absolutely unplayable after 1.21.0 (stuttering)

Have been playing since March 14th with absolutely no issues. The major and minor stuttering has made this game absolutely unplayable. Before the latest patch (1.21.0) I would easily get 90fps every single game on medium settings (no raytracing and fps locked to 90). Now it constantly bounces between 40-90 fps regardless of map or graphics settings along with occasional major stuttering. Very very rarely will I get lucky and it will stay at 90fps for a game.

My PC specs:

• 5070ti
• Intel Ultra 9, 2900mhz, 16 cores
• 32GB DDR5
• 2TB M.2 SSD

What I have tried:

• deleting shader cache for game and gpu
• reinstalling the game
• restarting my pc
• turning graphics to low
• installing latest gpu driver from nvidia
• making sure my power plan isn't affecting performance

I'm not going to reset my PC or format my drive as others have tried and failed.
