[Bug] Random connection problems - stuttering without lag

@MrPhotographerXHi, this might help you. It's a strange fix... but it worked for me. In short: empty your friends list (and blocked players from EA account) because the game constantly checks who is online. And turn off Steam overlay or install game through Origin (you can merge accounts Steam|Origin and keep all progress).

In season 13 this issue still is a thing, it just happen to me in a ranked match with cable connection 

@AreYouShivering  i didn't get a notification sorry for the late reply. a "fix" in a only multiplayer game where you have to remove your friends its kinda "bad for the game " 

"hi here have a multiplayer game but you can't add friends to your list or else you will have lag without having lag so... play alone" 

I have already steam notifications blocked , is that it? 

I will check your video later, thanks for the info , this is just some bad rep for respawn's work

As someone who dealt with stuttering on both xbox and pc in apex I found the solution after trying every fix I could find out there. Get a Solid State drive. Even just a smaller one at 225gb. You can right click on the game in origin and move the game files to it without redownloading. Then if you run windows, go into your advanced setting and put 8000mb minimum to 10000 (or more) max set to that drive. The stuttering I experienced was due to the game having to constantly access the HDD, it can't keep up, an SSD can. Have not experienced a single stutter after many games played since I did this. I can now stream, run discord and increased my in game Field of View (FOV) from minimum to maximum, and everything now works flawlessly. None of which was possible before. An HDD is a bottleneck.
