Baldur's Gate 3 controller support explained

Does Baldur's Gate 3 have controller support? The Larian DnD game is here, and it's the perfect game for getting comfy with a controller while your character does all the hard work adventuring and battling foes. However, there was no controller support for PC during early access, so we had to find out if this was among the many release day changes.
Baldur's Gate 3 is here and Larian has announced a multitude of changes from the early access build. Alongside new BG3 classes and races, one of the changes we've been keeping our fingers crossed for as Baldur's Gate 3 rolls out is the addition of controller support - especially given what we know about BG3 Steam Deck compatibility. So, here's everything we know about using a controller to play Baldur's Gate 3.
