It is still terribly broken for me. At least it wasn't until I downloaded the "hotfix" and it broke the game completely for me. It is so slow it's unplayable.
Sorry to hear that it's still slow on your side, I would reach out to the support team here:
https://larian.com/support/baldur-s-gate-3#modal (if you havent yet!) and let them know the platform you're playing in, so they can take a look.
