No reason to get mad at me. I'm just trying to help.
I've seen this issue in plenty of games. An improper network setup, or a setup where the hardware for some reason is having issues, but works fine for plenty of other games until this single random game comes along that utilizes the network in just the right way to expose its flaws.
I agree that consumers should not have to mess with extra steps to get their games working but I think that predicates that their system is working correctly to begin with. There're no gaming system in existance that doesn't have something wrong with it, not mine, not yours, noone. That is PC gaming, sadly they don't teach people troubleshooting in school ^^
There is ofc. the chance that it's a game issue, but I think we would be seeing more threads on here about that if that was the issue. It's up to you if you want to try my suggestions for workarounds/fixes or not, if you insist on thinking it's a bug you can report it in the bug section on here.
