PC gamers can now get involved with the 1.4 patch for Skyrim, but they do so at their own risk (according to Bethesda).
Gamers who have experienced any of these problems will be able to try out the new beta. On their blog Bethesda has warned potential testers: "Be sure to back up your saved games or simply be careful not to overwrite your existing saves. If you decide to opt out of the beta program, your old saves will still work with the current release of Skyrim (v 1.3)."
Game Informer first spotted that the fix has been made public. If you've been having trouble with the game, then this may well be the answer to your problems. The update is only available on Steam.
