About half a year ago, I moved to Canada and got a new PC. I was very eager to finally play Skyrim, but when I started playing it, I noticed (in the "brick in the face|" kind of way) that ALL my controls were delayed. I installed and tried Oblivion, Fallout 3, Fallout New Vegas, and they all had the sme problem: every time I pressed a key, or moved the mouse, it took around one second before the character moved ingame. I have no fps problems, only with the phisycal controls. The 360 controler is off, V-sync is off, the only adapter is the NVidia one, I even tried some .ini modifications and nothing worked.
I tend to think that it's a problem between the games engine, and my pc. This affects only and all the Bethesda games.
