The ENB is based on nWo51289's GOH. The mod was built in such a way that at high quality there is a slight loss of performance. The new Timecyc will bring you a beautiful night and generally it is not too dark (except in the deserts, it is a bit dark in some areas).
There are 3 settings you can choose depending on your computer's performance.
This ENB package includes:
Normal maps
Shadows
Improved lighting
FXAA + custom shaders (thanks NWO)
ColorMod and Bulletholes plugin.
Installation:
Simply extract all "ENBSeries" files and folders into the GTA SA measles folder. If you want to change the configuration, open config.ini in the ENB folder.
