Someone playing cs2 Arch Wayland KDE without problems?

I'm having FPS drops to half when I'm playing over a hour. I have try to enable and disable vertical sync and Nvidia reflex without success.

I'm playing 4:3 in one monitor and obviously without Proton (because I read that your account could be banned)

I have tried playing natively and with Linux Steam Runtime enabled, I tried to wait for vulkan shaders... Nothing.

It's strange because if I reboot the game its works perfectly again.

Someone knows some start parameter or something??

Thxx
