Hey @FeistyFlamex,
Apologies for the delayed response on this.
If you're still running into the same stuttering, can we try out a few things to see if we can help fix it? A good place to start out would be with the basic and advanced connection troubleshooting steps from the EA Help website.
It might also be a good idea to try starting up your PC in a Clean Boot to see if that helps as well. That way if there's anything else running that's connected to these issues that could help narrow it down. For more details on how you can set up a Clean Boot check out the EA Help website.
If you're still running into the same issue after that please let me know. Thanks!
