PhysX byl, spolu s několika ostatními GW moduly, uvolněn na GitHub už v roce 2015 ale stále není open-source.
Nějak nemůžu najít co přesně se změnilo. pořád musíš mít registraci na developer.nvidia.com, stále potřebuješ odsouhlasit restriktivní EULA a stále je použita restriktivní 3-clause BSD licence

Bohužel jde jen o další PR blaf :/
//EDIT: Tak jediná změna je ta, že nV už neposkytuje předkompilované knihovny, takže je potřeba je zkompilovat.
