Laggy game with high FPS

I’m gonna need my PC geeks so I got a 240hz Monitor and I consistently reached this at valorant most likely over 300+ FPS

I don’t exactly know when it started, but in the past couple of months it feels like I’m playing with 120hz Even if I have over 300 FPS. My Nvidia setting is On low and I setbmy monitor refresh rate onto 240.

I don’t know what I can do. I try to overclock my PC.
But nothing really helps you guys have any ideas?

locking the fps might help?

check ur monitors refresh rate in the properties

Ive had this same issue for so long and I fixed it, 1) Disable cpu0 2) Uninstall all xbox apps unless you use them.
