I would worry about how the game would run using your laptop’s integrated Intel UHD graphics. As with desktops, to run modern games well, you’re probably going to need a dedicated graphics card. As my gaming laptop has a separate Nvidia card, I’m afraid I’m not sure how BG3 would run without it.
Perhaps someone else can advise, but if in the end you are worried your laptop won’t run the game and you’re not able to add a graphics card, then there is the option of streaming using
GeForce Now, though I imagine that then puts the pressure on your internet connection instead.
