Shader and process on GPU

Per

Say I got a particle system with 200 particles which are checking the distance between each particle to draw lines according to the distance etc.

Say I want to have the same particlesystem but instead of using 200 particles I want to use 2000 particles. That would give me a terrible framerate. Even if Im using P2D or P3D.

I have been looking a little bit into shaders and wounder if it would be an better option to do the calculation on the GPU?

Would it be possible to write a shader that are doing all the calculation on the GPU instead?

Thanks

Good Luck :)

Hello

some more detail on this one. You can load an Array(positions, whatever) in a 1 2 or 3D Texture, and the manipulate it in a shader.
