A patch released today will allow those running 64bit operating systems to use 4GB RAM in Skyrim. Hopefully this will mean the game(already runs pretty damn well) will be even more efficient and smooth. That’s about the only major improvement in 1.3… but it’s a big one. Apart from this patch, there’s a new UI mod that make the Skyrim UI more PC like. You can check out SkyUI here. If the Skyrim default UI really annoys you I suggest you check this mod out.
