I am attempting to make my first networking game on GM, but I am having large lag spikes very frequently. In my code the client sends the sever the current_time, server sends back that time, and client compares that to the current_time, giving me my ping. The game is running at 60fps (both server and client) and moving to 30 fps helps nothing. I am using a tcp connection and 127.0.0.0 ip adress the game window is 400*250, x axis is just under 7 seconds of time, and y is the ping, so anything over 250 doesn't show. (the base line is 16/17 ping, perfect for 60fps) This issue doesn't happen anywhere else on my PC, browsing or playing games Any ideas what could be causing this to happening?
