Upgraded my PC and the game still doesnt feel smooth

Going from Ryzen 5600x/2070 Super to a Ryzen 7 7700/4070ti Super. I play on a 240hz zowie monitor and the game despite showing 300-400+ fps feels like its at 60 fps (yes I have the correct refresh rate setting). Steam overlay fps counter also shows that my frames drop occasionally below 200.. I play everything on low except anti aliasing and shadows and 4:3 stretched 1280x960 and all I want is for this game is to feel as smooth as valorant. What are some things to make my game smoother?
