I am just tossing this out there.
I just got a PhysX accelerator board for christmas and so far the demos, games and UT3 mod that supports it really impresses me.
I was wondering if future GC games might benefit from hrdware physics support or at least having the option to offload the physics engine to a physics processor freeing the CPU.
As ginormous as the real time action gets in this game it seems to me that a space sim like this is the ideal candidate for a physics processor.
