Yet another replacer for the main menu, it adds Alduin's Wall but using the actual mesh you see in game, so you get:

+ It's nice shaders
+ In game textures (if you're using a replacer, this one should show up)
+ The ability to manipulate it's position with nifskope (the X axis is your best bet, that's horizontally, the other axis are a bit wierd to adjust).
+ You can change the Emissive Multiple too to adjust it's brightness. (in nifskope, BSLightingShaderProperty)

I don't know about loading times, but I didn't notice anything horrible with mine. Tested with 1920 x 1080 resolution.
