https://www.gamecity.ne.jp/doax3/yawaraka.htmlDOAX3 on PS4 (Both Fortune and Scarlet) have Soft Engine 2.0
DOAX3 Vita has what they called Soft Engine Lite which has boob bounce, and apparently some see through costumes. However no string physics, tanning, butt bounce, etc
DOAX3 Switch has "Soft 4D" but they don't elaborate on the differences like they did on the PS4/Vita ones.
