I don't mean the HDD maintenance thing in system memory, that's different. Is there a button press/hold method like in Oblivion and Fallout 3/New Vegas? I know the cache gets cleared if you play three other games, and, after playing three other games, I did noticed textures had appeared on potion bottles for example in my inventory that have never appeared before. Short of playing three other games to clear this game's cache is there another way such as holding A whilst it loads?
