This mod is originally created by SonicJumper (original thread can be found here). SonicJumper couldn't finish the port to 1.8 (not enough time), so i did it. Eventually the mod got new effects. Feel free to give some feedback.
In order to use EnhancedVisuals alongside Optifine, Fast Render, Anisotropic Filtering and Antialiasing has to be turned off. Otherwise your screen will turn black when certain effects are active.
