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.

Im using starlink so i tried to relocate the dish.
turning off firewall in my asus modem
turning off firewall in my pc
turning on and off qos
