quote:We appreciate feedback from the gamer community and based partly on comments like the one above, we have identified an area in our driver where fine tuning positively impacts frame rate.
quote:I wonder if the types of computations employed by our controversial little PhysX accelerator could be harvested *outside* of the gaming environment.
quote:(slower probably than just letting the CPU process the extra crap)
quote:Too bad not even quadcores will be able to outperfrom the PPU when it comes to physics calculations.
quote: jumping to any conclusions.
quote:it isn't jumping to a conclusion to say that the PPU is *capable* of outperforming a quadcore cpu when it comes to physics calculations -- that is a fact, not an opinion due to the architecture.
quote:It is a simple fact that a dedicated processor for X will always outperfrom a general purpose processor when doing X from a hardware perspective.
quote: Assuming that the PCI bus is not holding back performance of the PPU, it is incredibly unlikely that quad core CPUs will be able to outperform the PPU.
quote:Some destructable objects do break off into real persistant objects under PhysX -- like the dumpster lid and car doors.
quote:I hope that they won't need a respin to add pcie functionality but fear this may be the case.
quote:I agree with the post that in volume, this kind of chip could find its way onto 3d graphics cards for gaming.
quote:Use it as a door-stop ?
quote:Pray tell me where you plug one of these if you have the following:
quote:It seems most likely that the slowdown is the cost of instancing all these objects on the PhysX card and then moving them back and forth over the PCI bus and eventually to the GPU. It would certainly be interesting to see if a faster connection for the PhysX card - like PCIe X1 - could smooth things out....
quote:We're still a little skeptical about how much the PhysX card is actually doing that couldn't be done on a CPU -- especially a dual core CPU. Hopefully this isn't the first "physics decellerator", rather like the first S3 Virge 3D chip was more of a step sideways for 3D than a true enhancement.
