I feel you on that front. I have a Steam Deck and use it over my PC 90% of the time and even have BG3 running well on it but I prefer to sit at my desk for this game because the clutter is so dense that I need that big monitor and mouse to pixel hunt for all the little items and clicky things hidden around the world... and being able to spin that camera quickly around with a mouse while traversing is super important to catching things
