This is another excellent idea for MP. The engine can already render the cross-eyed/Oculus 3D, splitscreen can't be too much more intense. (Maybe. IDK how Torque works, maybe a lesser area of detail around each player?)
this wuld be soooo fun i hope this thread isnt dead btw it wuld be more awsome on lan so the host runs physics and the joining people just remote the cars. ive also wondered if it wuild be more fps frendly if online servers got pc info when joined and when two cars got close the fastest of the two comps/laptops runned the two cars. guess there wuild be a small freeze when it change to run them
