PhysX on PS3?

post #1 of 10
Thread Starter 
According to the Valkyria Chronicles box - it uses PhysX by Nvidia.

I thought PhysX was a PC only movement kind of thing.

PhysX can be done through software as well. It likely just uses the untapped power of Cell.

Hmm, isnt the GPU inside the PS3 similar to the 3850? This is what i hear.. *JaKe*

Similar to the 7800 series (nvidia, not ati )

Well thats just it.
I thought PhysX does physics via the GPU, not the CPU. So would that not be contradictorily to everything?

Well if the GPU was based on the G80 cores, I would've said the PhysX is emulated by the GPU just like they do on the PC, but in this case I'm not sure if it's the Cell or the GPU...

PhysX can be done via CPU OR GPU. It just does it more efficiently when done on the GPU. See here.

Yep, for that reason I can play UT3 (uses physx) without having a physx card or an nvidia GPU.

Physx works through CPU or GPU. It just does calculations in such a way (very parallel) that it benefits from GPGPU technologies.
