Sorry to bump up a thread that hasn't been posted in a week, but this was in the sticky and I didn't think it called for a completely new thread:
I've been having this problem in the benchmark, closed betas and open beta, and I've asked on the official beta forums but no one really likes to answer on there! During the main cutscenes, most of my sound effects are out of sync with the animations. The voice-overs are completely in sync, but footsteps, wooshing sounds, gunfires, smacking sounds and whatnot, they all decide to play between 10~20 seconds after the animation has played. My computer isn't lagging at all graphically, and the non-cutscene sound effects are perfectly in sync, it's just the main cutscenes that are acting up.
I've only seen one other person post this issue, but it wasn't their biggest issue so no one ever answered them. All of my drivers are up to date. Please, if anyone has any information, I'd love to hear it! Thanks!
