Well the problem is that my machine while within the recommended specs, does not run the game well because 1.3.10 killed my FPS. Granted before I could only run the game at Medium to medium high settings. Now, I can only run the game at medium / low settings with LESS FPS. Bethesda dropped the ball on this, I think they should help us somehow. For instance I would not complain if they made it so people could install the vanilla version. The vanilla version ran well enough on my computer.
i very much doubt that valve will update steam to allow people to install specific version, so as skyrim is a steamworks game, it's a sure guess you won't be able to stick to one specific version. in a perfect world, this wouldn't be a problem, but all major games released on steam in my experience had some game breaking patch released (was the case for empire total war, civ 5, mafia 2 and, well, skyrim)
