I decided to post this shader (as OSP) Power Field Sharpening Shader and color correction. The shader is made as injector based ENBseries.Redesigned for M&B/Warband. Shader sharpens textures and models and also makes color management (correction), now the game looks a lot more colorful and real.

Installation: Copy the contents of the archive into the game folder.
Note: OFF - ON shader using Shift + f12.

You can use it in your projects, mentioning it in the credits.
The shader has almost no effect on performance. :)
