Utilise GPU just for animation/physics, not rendering I realise that the GPU can be used in Blender to accelerate rendering, but can the GPU be used to just perform animation/physics simulation?

I'm currently using Blender to import some OBJ files, apply some physics modifiers to them, run an animation/simulation and export the resulting OBJ file, i.e. I'm not using Blender for rendering purposes at all.

I did some performance tests and it seems like a GPU can only utilised for rendering and does not affect the animation/physics simulation performance. Is this correct?

Does anyone know if it's possible to utilise the GPU for physics simulation with any software?
Note: I require soft body (cloth) collision physics, not just rigid body.
No, unfortunately GPU based processing for operations besides rendering is not available at the moment.

It is possible (check out this demo by Nvidia), so perhaps it will be in Blender sometime in the future :)
