This is possible with A7, and probably most other engines. I don't see any realtime shadows. I currently have envbumpmapping + static shadowmaps as an option for my levels in A7 so what I see there isn't a problem. A7's only problem is that a very small fraction of the users can import worlds like that because you need 3ds Max and the Max2GS and Max2Mdl exporters alongside Ventilators plugin, and you have to export all your models twice with different uvmaps for shadowing. This takes a bit of knowledge, never mind the talent and skill needed to develop the art in the first place. Hopefully the new FBX import will materialize more quickly in terms of functionality and ease of use and everyone will have the benefits of an easy scene import to WED. However, I do agree that A7 is slower than other engines in terms of similar scenes... Although I don't know if it's slower than Torque.
