I'm having a lot of problems with the game selecting the wrong level of multi-level areas since I picked up this playthrough after a month or two off. It's a major pain and I don't know what's different that is causing it. I seem to have a bit more lag, as well, but that might just be my memory playing tricks on me. Either way, I try to click where I want my characters to go, and it'll frequently target something on the wrong level (usually under) and the characters will scramble around trying to find a path, usually running in the opposite direction of where I'm trying to go, and disappearing off my screen before I can figure out where they went to.
Are you by any chance an Old Age Person like me? My son keeps on grumbling that I'm playing almost exclusively with the mouse, instead of having my fingers dance over the WASD keys ...
I mean, I've been playing video games since the 1970s?
But I use the WASD keys to control the orientation of the camera, and the scroll wheel on the mouse to control the height of the camera. So, I'm not EXCLUSIVELY using the mouse, but it is my main input device for the game. It shouldn't matter for the problem I'm having, though.
EDIT: Though, I must admit, I'm very much looking forward to controller support promised when the game launches. Mostly because the interface looks bigger and therefore easier to read. I play on my TV set, so not on a monitor inches from my face. So a lot of the user interface is impossibly small to read without physically standing up and walking over to the TV screen, it's very frustrating. I can only imagine the challenges people with actual disabilities have trying to play this game. It's a real shame there isn't a simple way to scale up the text and the user interface. Solasta is so much better in that regard (though not perfect). In fact, so MANY of my problems with Baldur's Gate 3's gameplay simply don't exist in Solasta, that if I had the kind of rich character-driven story experience with that game that I'm hoping to have with this one, I would uninstall BG3 and not look back. But I really want to play a story-rich game like BG3 is promising to be... I just don't want to struggle with the interface every dang step of the way.
