Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - Bugs & Technical Problems Light Shadows causes huge black artifacting. [PC]

I'm getting that with lighting quality high & light shadows.
It goes away in medium quality.
It blacks out the painting scenes at the difficulty/game mode selection.
It never did that before (but different nvidia driver, now using the 399.07 too).
