WHY does DFORCE take so long.......

Why does D FORCE take so long just to find out after 10 hours of simulating a 250 frame animation, the cloth item goes crazy.  Is there a quicker way to simulate or speed it up. IT takes just as long to simulate as to render in NVIdia.  I need some suggestions!

    If it's taking 10 hours to run the dForce sim, are you sure it's running on your graphics card and not your CPU, which is going to be a lot slower? Both your graphics card and your graphics card driver must be capable of running OpenCL 1.2 — that's OpenCL, not OpenGL, which is a completely different graphics card feature important to running DAZ|Studio and Iray rendering. The alternative, running on your CPU, also needs the proper OpenCL drivers. Have dForce simulations always been this slow for you, or is it just this one animation?

    10 hours = 600 minutes; 256 frames is 154 seconds per frame; that is pretty quick.

    Almost three minutes per animated frame for a dForce sim is not quick. That would mean it would take 90 minutes for an average animated drape of 30 frames.

    My suggestions: turn off things that are not necessary. Any props that don't collide should be hidden during the animation, especially any high poly objects like strand based hair (unless absolutely necessary).
