how do you do animations with dforce hair?

Not something I'm currently able to do at the moment due to my graphics card but it's something I'm entertaining the thought of in the future.
But I can't figure out how you would do animations with d-force hair, since d-force hair has to simulate. How would I keep the hair from clipping in the animation? I guess for that matter how do you do dforce clothing too?

Animate your character without thinking about the hair, but start at like frame 75 or 100 so there's wiggle room to start with if needed and then it works the same as a still frame except if the first frame the hair is clipping in the body, then you'd have to start from a memorized pose so it wouldn't clip. If it's not clipping, then you can leave the character in their first key pose for about 75 frames for it to settle, then the dForce will do it's magic and then you have your animated shot! Same with clothes.
If you apply an animation and run dforce through the animation, it will calculate everything. It doesn't reset the dforce between each frame, but rather re-applies the results from the previous frame to the next frame, so the hair will naturally sway, bounce, etc.
It really doesn't take much longer, since it's only small adjustments made to each frame.
I never had tried dforce hair before and just last weekend I bought Classic Blowout Hair since it was on discount and it looked amazing.
What GPU do you have? I have a mere GTX 1660 Ti but it still simultates at about 1 frame a second as it animates the simulation for this hair product and the results are astounding for still renders but I have not yet tried rendering out an animation to see if it looks convincing.
As suggested earlier you would start your Genesis figure in a neutral pose at frame 1 where the hair or clothing product is not intersecting with anything that would cause collisions and dforce blowout / explosions.
Let it settle for a few frames - eg. 30? then begin your animation.
I'm not sure how good dforce is at solving intersection issues and pushing the dynamic mesh/clothing/hair out from Genesis - the old dynamic cloth engine (optitex) for DAZ was very good at that and still works so far as I know.
