For a more in-depth explanation, here are the original notes left by noko12312.
First off want to give credit to Havoc who actually made this mod. I Im just uploading it here so more people can find it. Introducing LodMod, this patch: - disables the buggy face-LOD system (fixes NPC faces being low quality when up close) - allows you to remove the DoF effect from the game - fixes rendering resolution being lowered / blur being applied in first-person mode - raises the object draw distance for each of the "Geometry Detail" settings - includes a small patch that increases objects draw distance to around ~175% Each of these patches are split into seperate patch files, so that you can pick & choose which ones you want to install. Before/after pictures in description.
First person blur:
Inside the zip is a patches.txt file which describes each of the fixes, to install them just read the instructions inside the included readme.txt file.
