I have a AMD 3700x (Old CPU) and I have stuttering as well, but Ive noticed when I stutter, I also have some type of lag as well. Like my brother and I was playing and he's fussing at me cuz he thinks I am kidding around with him and not moving, but I was moving on my screen. The last 3-4 days the servers have been laggy and my stuttering had gotten worse. I rebooted my router/modem and for now its better, but not fixed. I went back to AMD Drivers 25.9.1 they seem to work better then the newest 25.9.2 drivers, they kept crashing me, lagging the hell out of me and getting Query Timeouts every 10 mins or so. Id check drivers 1st because it doesn't affect my RTX 2600 system at all. I do play at High/Medium settings on my machine at 1080p mostly. 6700XT/16GB DDR 4/3700x CPU and 1gig download and 50Mbps connection. The servers are just messed up right now for a lot of people.
