So I've been playing a bit now. Definitely need to up my vid card or something, but I'm on lowest settings and at least the game is fluid.
Super early-ish quest spoilerage below.
When you first get to Concord and you find the settler bros, that first fight against the Deathclaw was super tough. Maybe I was doing it wrong. Eventually beat him but feel like that should've definitely not been so hard for being so soon in the game lol
