Apparently the first patch for Skyrim is creating more problems for players than it's fixing, making the game experience difficult for many players.
Resistances are just flat out refusing to work for many players, meaning that regardless of what items or equipment you have that's 'supposed' to help, it doesn't make a difference. Frame rate issues that were supposed to be addressed are still an issue for some users.
Oh, and some of the dragons are flying backwards. Maybe that means that when they attack, you have an easier time running away, since they're moving away from you when they think they're moving towards you? Or maybe it just means that the initial breath attack misses cause they're shooting away from you while their back end is going to you? Dunno. But if you really wanna try it, feel free to update. Otherwise, stay away until Bethseda does some more fixing.
