Soon after Nvidia bought PhysX I remember them showing off a demo of a (at the time) new game that was on the PC using their newest graphics card (the Geforce 9800 IIRC) and the GPU was able to handle the physics engine while rendering the game with ease. From what I remember of the discussion, the Physics engine was using (something like) 10% of the GPU's total processing power but was more demanding than anything that could run on a CPU. The reason for this is that a modern GPU can (in theoritical performance) be about 10 to 40 times as powerful as a CPU when it comes to floating point calculations that can be performed in highly distributed algorithms, and a physics engine is a (near) perfect match for this. We don't know much about the Wii U's hardware, but I wouldn't be surprised to see the physics engine offloaded to the GPU and the workload on the CPU to be reduced enough that it doesn't matter whether it is super powerful. |
well in planetside 2 you can activated phisics on the GPU (if your gpu can do it obviously) when i do this the fps doubles and all the action is more fluid (phisics), explotions and enviroment gets better, so this thing of using the gpu is real.
