I have one character that I can play for hours. My other character gets disconnected within minutes of logging in.
After testing one factor after another (unequip everything/in combat vs out/different locations/camp up or not up/etc), I still can't keep that character connected more than five minutes. And I can still log in on my other character and play just fine.
After sending them all of the information they asked for, after doing all those tests, they finally got back to me with their solution:
I meet every requirement (and all of their 'recommended') except one: Their CPU requirement is "Processor: Intel Core i5-6600k 3.5 GHz/AMD Ryzen 3 1300X 3.5 GHz or equivalent". Mine is an i5 4670k 3.4 GHz. 0.1 GHz slower.Thank you for contacting the Bethesda Customer Support Team and your patience in waiting for assistance. My name is Daniel and I'll be happy to assist you today.
I understand you are experiencing poor performance with Fallout 76. I'll be happy to investigate what's going here for you.
After investigating I've found that you do not meet the Game's system minimum requirements.

If you continue to have issues, we will be unable to assist with further troubleshooting as you don't meet the minimum requirements. I understand this wasn't the answer you were wanting, and I truly want to provide a different one, however I'm afraid our hands are tied here and we are unable to assist.
They won't help me with my 'poor performance' - my performance is fine. One character plays just fine, the other is broken.
And they won't help.
Fuck Bethesda. They've been sliding downhill for years, and now I've lost all the respect I used to have for them in the days of DarkUI and the Morrowind project.
