How to Make Minecraft Shaders Not Lag At all?

I have recently reset my computer and hav just installed The Minecraft GLSL Shaders mod and no matter wat shaders pack I use it lags I would like to get 50 fps with the seus ultra motion blur and packs similar to that my computer has 4GB and I think that's enough. So wat do I do

First of all when you throw up in the air a question like that, we would be happy to know your computer's statistics. Can you please edit your message and type your CPU, GPU, RAM (Already said), etc.
Now I have a CPU i7 3770 with 3.4GHz, a GPU GeForce GTX560 and 8 RAM, and my PC is 1 year and a half old.
Inspite all that I get around 30-45 fps on shaders ultra moition blur and the reason is the shaders detail. You need to be inside a world of yours in minecraft, open up the shaders settings menu and if you see the ShadowResolution or something alike, try to minimize it. All it does is making the shadows less detailed and more squared.
It did worked for me and I hope it'll work for you, too!
Have fun.
