So I've been replaying Divinity: Original Sin 2 on PS5 in anticipation for Baldur's Gate 3. I originally finished D:OS 2 on base PS4 back in 2019.
The game has some glitches with flickering shadows, specially in dungeons and caves. Not too prevalent, and not game breaking, but it's noticeable. I recorded a brief video to illustrate:

Also, the game is locked at 30fps most of the time, but sometimes going into battle mode unlocks the framerate for a second and it shoots up to 60. Certain spells and effects also seem to unlock the framerate temporarily.
Thanks for the feedback, i've search and found some other users with this issue too, i will include a note in this game in the next time i update the OP.
