I played in beta and i dont have issue but when i play on live my ping would shoot to 1000 to 4000. and it only smooth on the first 10 minutes or so. I dont know what else i should do so any help is appreciated.

turning off firewall in my asus modem
turning off firewall in my pc
turning on and off qos
turning on and off ipv6
changing poton
I tried several ping checker and in my browser everything seem normal


Not sure why you’re getting downvoted, but I wonder about that, too. SteamOS is primarily focused on Valve hardware, right? vs. something like CachyOS is Arch-based (so gets live updates/improvements ASAP) or Bazzite (immutable, so hard to break) and both are designed for general PC gaming, so likely have more attention to broad hardware/software/firmware compatibility.
If I were OP, I’d try live booting CachyOS to see if it works better.
