The Meaning of Life, the Universe, and Everything.
I am using shaders (Paolo's, LikeMinecraft , YShaders(Which Works), kuda shaders, and Mr.meeps shaders) Yshader's work but on the medium setting, but It has no shadow, and high is just completely black. Now onto my question, Paolo's and Likeminecraft Support My Computer (At 30 fps) but at night the screen will start to flash repeatedly, while kuda will black out (Just like Yshaders High) and Mr.Meeps will be black, (In the Third Picture). Here is a picture gallery of me running Paolo's, LikeMinecraft and Mr.Meeps. https://imgur.com/a/710Im .
I wouldn't recommend using shaders in 1.8 currently, it is pretty new(few months old) and is no where near complete. They're still fixing bugs and glitches, which this might be. most likely the shaders and 1.8--something probably doesn't mix yet. Also bumping is not allowed.
