So I have an odd problem. Whenever I startup CS:GO I get a massive amount of stuttering and freezing from my internet. I am on ethernet, have good ping (30-50) and my ping never spikes. It also does not show any spikes in choke or loss ingame, so im wondering what could be causing this? I've reset my router, changed my ethernet cable, and I have plenty of bandwidth. Should I call my ISP?
