Apparently putting CPUs on our graphics cards that often out-clock our main CPUs is not good enough. Now we're supposed to plunk down $300 for an add-in card (PhysX corp's "Ageia") that accelerates physics computations. So that we can, um... throw around fifty times more crates. I'm generally loathe to bash anything that makes life easier for game developers, but remind me again, how is this making gameplay more fun and interesting? Didn't Half-Life 2 do this better, with less CPU cycles?
(Someone at the Digg story commented that rigid body/rag doll physics is not a particularly hard problem anyway, and he'd like to see more hardware focussed on something like what Jernej Barbic and Doug James are doing at CMU. Check out the falling load of baskets at the bottom of the page. Though again, one has to wonder if this is really going to make games way more fun.)
