Well, Ds has almost bi weekly updates with things working and breaking from version to version.

It still doesn't handle scaling properly like poser does, but it's displacement renderings are much better, till the next poser 7 patch.

I think DS's previews are also slightly faster, but it's a tradeoff, because poser's preview is also handling some of it's proceedural textures as well.. so you add moe work, you slow the preview down some.

Also, Poser's space navigator support is killer!

Way too many people take way too many things way too seriously.
