So Minecraft is lagging, even though I've dedicated 2GB of my RAM to it. I usually get approximately 45-50 frames per second, though when I added the GLSL Shaders today, my fps was completely flushed, averaging at about seven frames per second. I've never gotten this low of fps when I added the shaders mod, I would usually get 20-30 fps when adding a shaderpack. Does anyone know how I might be able to fix this?

Take away the shaders mod -- which can be pretty devastating to FPS. If it's a must need, try getting Optifine as well.

Your system just isn't strong enough to run the specific shaders you're using. Try sticking with less intensive shaders.

This statement isn't actually true, I have 8GB of RAM.

Shaders aren't RAM intensive, they need a lot of CPU.

Awesome. Have a cookie.

The fact of the matter is that it is true. Whether you want to hear it or not. Whatever shaders pack you're currently running is too intensive for your GPU and you should consider getting a less intensive pack or simply not using shaders. Your RAM is irrelevant here. Alternatively you can turn down your settings. Smooth Lighting is a major one that people over look. Turn it off all together and you'd be surprised what it can do.

I gained literally 5 fps by turning smooth lighting off. Thanks?

Meh, Shaders aren't even that cool anyway....
I tried it and gained 14 FPS (with mods) on the least intensive shaders.

Who needs a cool looking Realistic Shadow.
And awesome lighting, cool water reflections....
The night sky, clouds.....

It all sounds pretty tempting but... Pfft who needs it.

(I gained 30-60 FPS with a mid-tier Shader Pack on vanilla)
(But who plays vanilla?)
