Much worse than the original two games, too.
The original 2 games were made by different developers in a different engine. So no wonder it would be different.
You're better off comparing the UI to other Larian games... Which aren't a whole lot better.
Of course, some parts of the UI also suffers due to facilitating Consoles. While there are some differences between PC and Console UI's, there is a lot of things that are shared. Which, always causes them to be clunky on PC because it has to work for controllers with limited numbers of buttons to interact with things. Notably, because of the shared release of the game on PC and Console (Compared to prior Larian titles that were released on PC first and then later a Console port was made after the fact. Meaning the original game was entirely built with PC in mind)
For that matter the graphics designer isnt an entry on the list either. You again have to find its very own button, again easy to miss.
I honestly have no idea what you're referring to by "Graphics designer"
The controls within the game are horrifying, too. You constantly have to move the camera separately to the group. That was actually in the original game, too, but there it was a 2D game where it made way more sense. In a 3D game its needlessly complicated to do.
I'm pretty sure there are settings and keybinds to have the camera follow your character. I know I explicitly turned them off because I'm used to playing CRPG's where moving the camera independently of characters is normal (And often better for actually moving, especially long distances, clicking to move directly on a location far away > constantly clicking to move to locations a few feet away until you reach that far away destination)
The formations from the original game have not been copied. You kind of control who the leader is, but everything behind is a mess. That often matters when battles start and the allies are very far behind.
At a guess, I'd assume that this is in part due to their auto-pathing mechanics. Where party members will do things like jump across gaps or even jump up/down elevations to follow your party leader. Which probably doesn't vibe well with the more traditional formation pathing.
This sort of thing also wasn't in Divinity titles so you spent more time manually teleporting party members across every gap you encountered. (Which was helpfully mitigated with the teleportation pyramids)
The original game was very big on having a pause and having a hard pause button and having automatic pause. In BG3 all you have is reload. I frankly dont get why people even bother with the ironman mode, I misclick far too often for that.
BG3 has the largest button on the UI being the "Enter Turn-based Mode" which is functionally a pause. It also has a keybind associated with it. This is actually better than a pause in many respects because it allows you to actually interact with the game in the turn based mode, meaning other NPC's are frozen in place and any timers (Such as temporary buffs) also don't tick down.
I think there are also settings for auto-turn based toggles. But I can't recall as I never desired to use them (As someone who also turned off most auto-pause interactions in older CRPG's since I found it more annoying than useful in most cases)
Every time I try to maximize a container, the container is closed and my character starts running around wildly whereever my mouse ended up. I just interacted with a container. I clicked on the bar that controls the size, then moved the mouse. So why does that give commands to the character ?
This is just a side effect of using the same button (Mouse clicks) for both movement and interaction. Alongside a somewhat janky container interface.
Meaning that a misinput (Either by mistake or due to janky interface) can lead to a character command. This happens to be a staple issue plaguing literally every "Click to move" game that ever existed (With the more commen thing being loot based ARPG's like Diablo where you can accidentally click on an enemy or item on the floor instead of moving or vice versa). Which is why it boggles my mind that this form of input is continually made instead of being replaced by many, much better systems (Like WASD movement - Which is actually what Console uses in lieu of click to move)
Meanwhile, this interaction when done intentionally, is fine. Most of the time I don't click to close a container and simply walk away from it, reducing the number of inputs I make.
Of course, containers and inventory definitely could use a spruce up in terms of design. I'm just thankful that it doesn't use the awful Tetris inventory of old but that's about the only positive there is. (And don't get me started on the horrendous trader UI... Which has not improved from Original Sin titles where it was also garbage)
Or what is the problem here ?!?
Most likely a lack of resources put into the system and instead devoted elsewhere.
The entirety of the UI design in BG3 very much feels like it was worked on up to the point where "It technically works" and then it was left alone. No refinement or polish, just the bare minimum to function (Which in some cases required a patch... Literally Bard's expertise needed to be patched to actually be changed, by default you literally couldn't change it at all. Made all the more ironic given that Rogue's Expertise always worked fine)
Where all these resources were put instead? I cannot say.
