I can do my physics calcs on the cpu or gpu. But if I use the gpu I am wondering if this will limit me on other effects that I could better use the vertex processor for. Is this true?
Also if I do the physics calcs on the cpu then I would need to transform my verts on the cpu, but the gpu is doing the same transformations faster,
so should I send the transformed data back to cpu or is this slower than doing my own transforms on cpu?
(I don't think the fragment processor is involved in this, correct me if I'm wrong)
