Also it’s a Larian game, so not only will it have all the thousands of bugs fixed (literally, the first patch had over a thousand fixes), you’ll probably get the Extended Enhanced Definitive Divine Edition that rewrites half the quests and adds a bunch of new ones.
Because when you are giant studio using Unreal Engine there really is no excuse for poor performance or porting. But when you are a (relatively to Epic or Sony/Microsoft etc) a tiny team building a game using the engine you came up with yourself with its roots somewhere around 2010-ish , back when 6 cores was a brand new thing and have been tweaking it ever since, you do get some slack if it doesn’t multithread perfectly.
