Whenever I do a sneak-attack undetected my character goes into slow-mo as if to make a cinematic effect which could be cool - but - the enemy I'm attacking (and every other game object) is at normal speed. This means that less often than not the enemy walks away while my sword is swinging very slow (and movement speed is slow as well) and I miss him. He hears the swing-sound and dectects me and a normal battle ensues.

So what would be a one shot sneak kill attracts the enemy and his friends instead.

What's up with this?!
