download ENBSeries v0.079 SORA for GTA 4

Warning! This version was tested on NVidia cards only. Quality of shadows must to be set to High or Very High. This modification works incorrectly with modified game folder "common\shaders", so leave it as in the original game patched to 1.0.0.3 or 1.0.0.4, overwise brightness and over artifacts will appear. Also check out your videocard driver setting and set them correctly as described in the documentation www.enbdev.com Antialiasing produce some artifacts on ATI cards, i don't have it for testing, so forget.
Added support for loading of external shaders for clouds generation and bloom. Implemented moon. To activate moon, place files enbmoon.tga and enbmoonbump.tga in to the game folder (tga, png, bmp files are supported). enbmoon image file must be with alpha channel. To change stars texture, copy enbstars.tga (png, bmp) in to the game folder. To change clouds texture, copy enbclouds.tga (png, bmp) in to the game folder.
v0.078b: Fixed bugs with lighting and reflection, added code for sky and clouds. External texture of clouds may be used instead of ingame procedural generator, just place file enbclouds.bmp in to the game folder.
v0.077b: added support of external effect file (effect.txt) and fixed bug of dirt on some cars.
v0.077a: adopted to use with patch 1.0.0.3 and 1.0.0.4, previous worked correctly only with patch 1.0.0.3. Visit enbdev.com for updates, documentation and effects.

Problems If some graphical artifacts (like too high brightness) are visible, restore original game shaders folder "common\shaders". In many cases other types of graphic mods change this.
