Followed the legion guy and heading through the dungeon, there is that part with the lever to lower a bridge which gets pummelled by stones once you're across. Every time the game will lock up a few seconds after that. Can't play past there, and I'm somewhat annoyed with that. I can at least alt-tab out and kill the process but this happens every time and precisely at that trigger so not much point.

Oh and the menus look like crap in ultra-wide resolution, but as usual I imagine the WSGF community will fix that on behalf of bethesda's devs, yet again. Not bad in 3240x1920 though. More interested in getting past this game lock up.

Okay...so reduced the sound playback quality in control panel from 48K to 44.1K as per that first post's advice on the off chance it'd do something and voila, it won't crash at that point anymore. On one hand thanks for identifying such a problem and providing a work-around...but on the other: Games shouldn't dictate needs like that, you should have fixed this before release.

Edit: Or not, went back in and the game locked up again going through that sequence. I killed the process and tried again, this time walking only far enough to get the NPC walking across the bridge, then waited for him to cross before I went across as I did that time I worked...and it works. That seems to be the crash condition, getting across the bridge first.
