When i started playing skyrim i tough it was really amazing. it was purple. i recognized this as textures not loading properly. Also sometimes some models would load making me sometimes invisible or interiors of buildings would be completely gone. Im not running a hacked/cracked or any mods, im using the pure Steam version of the game and
im running Windows 7

Also sometimes the game randomly keeps crashing to the desktop. I saw a thread about sound not being enough high quality but my headset doesn't support 24-Bit studio quality.
Does anyone know how to solve these problems im having whit the game?
