How to fix Skyrim's incredibly long loading screen caused by d3d9.dll?

I have just bought Skyrim, and instead of 3 hours of playing, I've been spending 3 hours getting it to work. I experienced heavy mouse input lag (about 0.2 seconds, try to block someone's sword with that). I fixed this problem using instructions in this video.

In particular, this instruction had the strongest effect:

Step 6: -download "D3D_Antilag_v1.1" and move "D3D9.dll" and "antilag.cfg" into the game folder (where the *.exe files are located) -open antilag.cfg with notepad and set "frames rendered ahead" to "1" (This forces frames rendered ahead to 1 and adds a framelimiter, which is required to fix vertical sensitivity issues)

Step 7: -open antilag.cfg with notepad and change "FPSlimit" to "50"

^{I downloaded it from here: http://www.nexusmods.com/skyrim/mods/34/}

However, as long as D3D9.dll file is present, game takes up to 7 minutes to load the main wasteland area and up to minute to load when you enter/leave a building. I found two workarounds:

1. Ctrl+Alt+Delete out of the game, when you focus the game again, the game will instantly
   • 70% finish loading
   • 30% crash
2. Read a book during loading. So far the only reliable workaround.

Is there a way to prevent this long loading problem? I have a strong suspicion it has something to do with FPS limiter, since exiting the rendering mode allows for instant load (if it doesn't crash, that is).

Renaming the DLL file to D3D9.dll.bak instantly removes the long loading and instantly re-adds the input lag, so this file is relevant to both problems. The game is unplayable with mouse input lag since I can hardly aim for inventory items and people. This means I desperately need to get the FPS limiter to work, otherwise I just wasted 15€ for nothing.

How to I resolve the long loading without removing the FPS limiter?

Solution 1:

The mouse lag can be caused by display driver problems.

Try updating your graphics card drivers.
