There's no difference between the steam and non steam versions. Why would you hope that so strongly? Not to say this issue wasn't a mistake, because it was, but still.
Steam is not bad, it's not evil, it doesn't hurt your computer, it doesn't sap excessive resources unless you've got a pentium 3 and 128 MB of RAM- it is NOT hurting your game's performance, no matter how much you'd like to believe it. Most of the bad things people say a bout it are just myths and lies spread by haters. If you didn't want to use steam in the first place, why didn't you get the game from another source?
