Lags/freezes with some new skills / strongboxes maybe sound related?

This is my thread with my observations about game freezing when loading new/randomized stuff (strongboxes opening, rogue exiles, ... and with Vaal Burning Arrow skill.

I think this MAYBE have something to do with sound/audio. Maybe. Im not expert. I just see that some things freezes the game (like for example discharge before) and some not. :)

Just saying.

Maybe someone can look into this in spare time. :)

Before game lags heavily on many skills (discharge, detonate dead, fireball, many others) but not anymore.

Maybe its the same issue here?
