Wow amazing! Do you mind telling me what programs did you use to do that? I usually use nvtools with the bat files found here (just for DXT comp., don't know if can also reduce resolution)

The only problem is... how to find out which textures are 2048??

The only problem is... how to find out which textures are 2048??
BSAopt (now you can unzip SKyrims .bsa archives
nvidia Windows texture thumbnails (nvidia.com developer tools). This will disaply the textures as thumbnails in Windows
Windows Texture viewer - now you can double click a .dds file and it will open up in a viewer. Observe at the bottom, in the status bar, it will tell you the correct file format. DXT1, DXT5, mip maps, etc.
Paint.NET (resize image, reduce by a power of 2 (512, 1024, 2048, 256, 128, 64, etc.). Save as... . be sure to use the correct compression format (DXT1, DXT5 ... see above), use default settings for anything you don't understand. Tick the mip map box if the texture originally had it.
Those are the basics.
PUt the textures in the proper folder where Skyrim can find it (when you unzip SKyrim's .bsa archives, they will unzip in the proper folder directory structure, so use that as a guide --example: Data/Textures/architecture/whiterun/wrdoor01.dds.).
Play the game.
