I wish this was possible too, 1.02 worked perfectly in my experience (aside from minor FPS drops) but 1.03 has ruined the game for me by reducing NPC populations significantly. Some area's are completely deserted where before there were 30+ NPCs.
I've started a new game without any patches at all, but version 1.00 is missing a lot of positive changes introduced in the day one patch (1.01). The water looks terrible in 1.00 compared to the patched game, but that is only the most obvious visual discrepancy.
I'm not usually one to complain, but I adore this game and I just want to play the version I've already put 40 hours into.
