Version 0.081 SORA - added limited support for game patch 1.0.6.0, but most of complex effects are ignored and still available on previous game versions (except 1.0.2.0 and lower, where also limited). Antialiasing, color correction and post processing by external files, reflection for cars and chrome, quality increase for reflection, bloom, sky and clouds, moon, some else. Shadows, sky lighting, ambient occlusion are ignored. Original moon by r* removed.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

here is some screenys i got from the site

GTA IV

GTA SA

GTA VC

if your pc lag to much with this use all the files in it but not the enbeffect.fx it will still make the reflection better and etc.(know it works on gtaiv)

also custom shades will work and wont give u lots of fps drop
custom shaders can be found on the site from random users

thx toVorontsov Boris (ENB developer)

gta sa
crysis
fall out 2
resident evil 4
driver 4
