I dunno man. I missed the boat when it came to vampire games, in general. I completely missed out on the first one. Although, I have thought about buying and playing it. But, I dunno.
That's what I did as soon as I heard that Valve had come out with a compatibility layer (proton). That was in 2018? I think? Haven't looked back since.
AMD vs. nVidia has become a moot point, nowadays. Unless you're playing games that have simply just come out, and you've gotta play them right NOAW! There's simply no point to buying an nVidia card. At least, IMO.
I consider Act 3 to be two separate acts. Act 3A, let's call, it, is Rivington and Wyrm's Crossing, and 3B is the Lower City.
Although, I do feel a drag whenever I'm in the Lower City. Just so much shit to do.
