I've posted about both of these bugs before but I really wanted to bring more attention to them as both of them are having a significant effect on my game...

1. Dragonbone Bow (Legendary and enchanted with Fire Damage and Soul Trap) arrows frequently lag. I've noticed a lag of up to .5 seconds, which is very significant and just plain ridiculous. I've used a Glass Bow for most of the game and I've never had this issue until buying Dawnguard and making myself a Dragonbone Bow. It doesn't happen all of the time, which is the only reason I don't toss my bow. That, and the fact that its damage is 351 without exploits.

2. Bats Perk audio loop when not in Vampire Lord form.. This is a strange one, and it doesn't affect my game, but it does affect me in real life. I've have alot of problems with repetative noises, and if they're loud enough, they constantly nag at my brain. This noise is just loud enough to bug me, so usually I listen to music while playing now... Annoying as frick, and it doesn't happen while in Vampire Lord form and out of combat, only in Human form.

I think Bethesda will release a patch when the DLC comes out in all of the consoles. At least that's my logical part thinking. The world isn't very logic
