GREAT FPS BOOST
- []Fog.esp (file 1). []Shadow and Grass Tweaks (file 1). []Meshes (file 2) : these meshes tweaks the flying particles, fog and mist, for more FPS (see details bellow) []Clear Weather : An optional "Clear Weather file, to prevent the lag caused by some types of weathers.
Its to help with fps/lag problems.
You don't need this if you are not having any lag. you can use any combination. I strongly recommend at least using the meshes, they are very helpful and i don't know of anyone that did these specific mesh tweaks before... to address the lag problem of the mist, fog and flying particles. Use all (tweaks + esps ... ) if you want the best results in exteriors and interiors too. Beware though that the shadow tweaks will remove most of the shadows. in my opinion, i prefer to have a smooth playable game that i can enjoy playing, so i don't mind sacrificing the shadows. Anyways, its all about your pc limitations, a powerful rig doesn't need any fps boosters.
DESCRIPTION :
[]1- The tweaks should boost your fps by tweaking the shadows (most of them removed). Please note that sunny days are still there, no big shadow everywhere . []The night time areas kind of blend together a bit more and the dark areas (interiors) are a bit lighter since the shadows are different . please note that even with "Darker Nights" installed it will look a bit lighter, so you may want to use a darker setting version of "Darker Nights" if you aren't running the darkest one yet. []Things like expanded metal with fire in them still cast their coolguy shadows, so the game does not look like it's had all shadows stripped out, for anyone wondering. []Note : the needed number of 9s in the tweaks can vary from one pc to another, the base is 6*9s. i am using
