I have seen this asked multiple times all over the internet but haven't found a proper answer to this yet.

Whenever I'm in third person view I experience major input lag on character movement, i.e., whenever I use WASD or my 360 controller's control stick it takes about 0.5 seconds for my character to actually move. However, in first person the character responses instantly.

What I have tried:

• Valve's tips on input lag
• Disable V-Sync (iPresentInterval=0)
• Uninstall all mods
• Delete .ini files (reset to default)
• Install proper keyboard driver
• Unplug controller (still lag using keyboard)
• Unplug keyboard (still lag using controller)

Other actions still respond instantly, including jumping, opening the menu or interacting with actors. It's really just the movement keys.

I haven't played Skyrim since 1.2 but I can't remember ever having issues with this. Same hardware as back then, too (GTX 570, i5-2500K).

Any solutions to this problem? Could this even be intentional?
