For the past few months playing games like CS:GO and Valorant has been miserable because I keep getting lag spikes that don't show on the in-game numbers, however when using the command prompt ping test it shows massive spikes that line up with when I experience them in the game. I have tried taking devices off the internet, rebooting the modem and router, tried playing later in the day, but it still happens at 2 in the morning. My ISP has been completely useless thus far in helping me out and I don't know what to do anymore because I am paying $120 and can barely even play games.
