Are these tesla cards able to be used to improve game processing? ie game physics
Haven't read up on it - but the short answer I would guess is yes, they theoretically could and probably will in the future, but no they probably won't very effectively at the moment. Unfortunately we're still in a world where people code in a single threaded way - perhaps using 3-4 threads if you're very lucky, but not much more than that. For game physics to truly take advantage of these hundreds of cores, people would need to adapt to a very different style of coding - process driven development. Have a Google / play around with occam pi if you don't know what I mean by that
That said, if software / physics were to be specifically written to take advantage of all this processing power then yes, I'd imagine it would most certainly give the physics behind things a lot more "oomph" (for want of a more technical term - but too tired to think of one!
