Are you playing in a server that matches the region where you live?
I live somewhere around USW, and if I try to play in an ASE server, I will experience lots of lag and net jitter in the game.
Check to see if you are playing the game in a server, if you don’t know which server is closest to you, just play in “Best Server”. If you already are, or this doesn’t work, then I don’t know what else to say, sorry
Hope this helps, and I hope it works out for you, good luck!
