I have google fiber, and overall fast internet. About a month ago on and off, I would have my PING go from a steady 50 then jump to over 5000, then go back down to 50 and so on. I have no idea why this is happening given that my settings are low im playing in my region.
I had the same problem for a long time, I just lowered everything in the video and graphic option which did not change anything in matters of colours or gameplay, but my ping does not explode anymore and I dont lag very often.
