Looks like more and more time and money is spent on developing physics hardware. ATI just revealed it's 'boundless gaming'
, their backend for Havok FX, meaning physics calculated on GPUs. Simulating 20000 objects colliding with each other looks pretty impressive like on this image
but another questions arises: Do I need this? I'd rather spend my money on gameplay or story telling hardware if something like this existed. Today's games would need it IMO.
