I've installed the GLSL Shaders profile for Minecraft 1.8 without using Forge, and it works fine. However, since now I'm not using OptiFine, I'm getting a rather large decrease in FPS, which is disappointing.
Is it possible to install OptiFine and GLSL shaders at the same time?

(changelog) shader support is integrated, that means, you no longer need to install Forge and GLSL Shaders mod to have shaders in-game.The shader options are the same as they used to be, same UI and same capabilities, - shaders work exactly like they would in GLSL Shaders mod.
