Re: Digital Combat Simulator: Black Shark
I don't think it uses PhysX technology but make no mistake... Flight modeling and weapons modeling have a very high fidelity. It's not really an arcade game though you can dumb it down a bit to get the hang of things.
That isn't to say it's impossible to fly. Reason being is this Helo has counter rotating rotors which counter's a lot of the problems associated with a conventional Helicopter. It's a challenge to fly and get used to it but it's not impossible to get the hang of things.
Sorry but I assumed you wanted to know about the FM given your PhysX question. BTW it does model wind and weather to a high degree of realism.
