Larian Studios Forums Baldur's Gate III Baldur's Gate III - Technical & Gameplay Problems Patch 9: Stuttering when casting a spell

I was just in the crypt with a Sorcerer. Spells began to stutter, then my game turn into a slideshow.
I have a Ryzen 5 3600XT - 16GB and a RTX3070. My GPU use was through the roof.
But having the same CPU as you, it could be linked to the new IA ?
Anyway the game began unplayable.
