Okay, I've had the game since release and this has never been a problem. Ever. Anyway, I was doing one of the Gauldur Amulet dungeons, and I first noticed something odd when I wasn't taking health damage from the spear traps - until about 5 minutes later.

Now I'm actually in Reachwater Rock and it takes a while for the claws to go and unlock the doors when I hit E. Even more irritating is the fact that not all of the appropriate doors go down at once so I'm stuck waiting for upwards of 5 minutes for one door to go down - then I wait for the next one. The same thing happens with the second door that you unlock with a claw.

What's even worse is the amulets - same problem with the claws but on the pedestals and with an even longer wait. Even when I somehow manage to get all three amulets in place the gate behind me doesn't close and I don't start the boss fight. I just sit there. I've tried waiting, but the gate never closed. This is unbelievable.

Ideas?
