30fps vs 60fps, GPU vs CPU (Gaming)

can the physics for those be run on the gpu now?

Yes, but most physics would be inefficient to run on the GPU and possibly inaccurate too. Thing about GPUs is that it can do the same mathematical operation in dozens of hundreds of inputs at the same time, but if you need each input to operate differently or need the result of one operation be the input of the next, the GPU will take a full cycle to get to that. Same with the CPU, but at least it isn't built with thousands of parallel cells, so you're not wasting processing power that could be better spent elsewhere.

Right, highly parallel manipulation of large arrays of data. What I was specifically wondering about was the integration of physics processing units with GPUs (like PhysX). My understanding of that integration is that it can handle the physics for particle systems (but not necessarily game simulation physics). Do console GPUs have that integrated now? Honestly I haven't followed GPU developments & what capabilities consoles have lately.
