Replaces the skybox with the old one and changes post-processing to accommodate it. Makes the game brighter. Wanted to call the mod "Daylock" but another mod already has that name lol.

There are two versions of this mod. Default and the alternative one. Default has a warmer and more saturated colour palette while alternative is cooler.

Difference between Default gameinfo and the edited OptimizationLock gameinfo is minimal, but having Optimizationlock as a base for your config optimizes the game really well. Main difference is FOV/LOD, on Optimizationlock gameinfo some of the buildings will pop in and out of existence. Both settings can be easily changed through notepad.
" r_mapextents " controls LOD
" citadel_camera_hero_fov " controls FOV

IMPORTANT INSTALLATION INSTRUCTIONS: 

The vpk is installed by just tossing it into the addons folder in 
\ Deadlock\game\citadel\addons . 
Or you can do it through your mod manager.

The archive with the mod also contains 2 gameinfo.gi files to turn off the excessive fog. First one is based on the vanilla gameinfo and only has the fog fix, second one is based on OptimizationLock by Sqooky. After choosing which one you want to use, change its name to just gameinfo.gi and replace the vanilla one.
gameinfo.gi is located in \Deadlock\game\citadel

Also check out tacticalpan's skybox mod. It keeps the fog while this mod turns it off completely.
