Re: How PhysX runs on Nvidia and AMD (ATI) systems


The performance of CPU based Physx is down to the developer, the only reason we see such big differences is because Nvidia wants to promote GPU based Physx over CPU based. It costs more money for the developer to get CPU based Physx working to the GPU standard. The GPU does thread allocation automatically and the CPU based Physx needs the developer to manage it.

I really doubt we'll see Physx as we know it like we see in Mirror's Edge, Mafia or Batman AC. I think SOE are using Physx as the Physics engine and it'll will be CPU based rather than GPU based. I really doubt physx will be used to see news papers flying about and shattering glass.


It really is down to the developer, Physx running from the GPU doesn't show much performance gain when it is made for the CPU right. I think I remember reading once that it was only a 10% gain on multi CPU applications.
