    Don't count on it without a 2nd card in SLI

    Currently yes that tornado map runs like **** and something happens when you are in it a while and it becomes like 5 fps everywhere in the map eventually, that will change for me when nvidia releases the patch to alloy physx to run on the 8 series card.
    It may run slightly better, but not much. It requires hardware to run the software. Your GPU will have to render as well as run the CUDA PhyX thread. Nothing is free, there is no extra unused part of the GPU. So if it takes 50% of GPU resources to run the physics, what would that mean to your FPS?

    Ageia PhysX with the dedicated PPU still requires a "high" end computer. Eliminate the PPU, and you will need an even higher end machine. Pretty obvious you will need 8800 cards in SLI or better.

    My very obsolete specs;
    Opty 180 @ 2.6GHz (socket 939)(AMD Dual-Core Optimizer)
    DFI Infinity NF4 SLI (nforce 6.85 driver)
    2GB DDR400 (value ram, 4x512MB single sided)
    2 X XFX 7950GT 570MHz 512MB SLI (169.04 driver, AFR2)
    BFG Ageia PhysX (1.1.1.14 driver)(quiet Vantec ICEBORG5 cooler)
    SB Live 24 bit (1.004.0055 driver)
    XP64 pro SP2 until Linux port arrives
    1600x1200, 3-3 quality, 38-85 FPS (I set a 85 FPS cap => refresh rate)
    1600x1200, 3-3 quality, 26-70 FPS PhysX maps
    21" Sony Trinitron G520, 85Hz refresh
    UT3 ver. 1.1

      So you are saying Nvidia are stupid enough to add this physics thing to 8xxx series graphics cards at the expensive of losing a considerable amount of performance? What's the point of adding it to existing cards at all if that's the case, they may aswell just make new ones with it on

        The point is to sell more GPU's. Nvidia knows already that you will need 2,3,or maybe even four video cards to use the physx stuff to its full potential, so it means more money for them.

          People are frigging retards. Seriously.

          Lots of cards on the market get 100+ FPS in UT3, when monitor's refresh's often cap out at 60. Any FPS more than 60 is a waste.

          With physx, these cards might get 60-70 or more FPS in Ut3. Sure, lost FPS... but its not really lost, its just being USED.

            BINGO! That's the whole deal!

              The point is that he GPU will have to both render and do PhysX. It still requires hardware. Will it require 25%, 50%, 80% of a GPU? For now, it's all supposition, we will find out in time. Obviously only the 8800 and better cards will be able to pull this off. So, what is cheaper? The GPU or the PPU? Will the GPU owner have to run at lower res or quality? So, running 1600x1200 with a 8800GT and 90FPS without PhysX. Then boom, turn hardware PhysX on and now only getting 35FPS max and dropping into the low 20's at times. You lose like 25% of FPS in PhysX maps with the PPU due to the increased load on the CPU and GPU.

              PhysX not only requires processing power, but increases the load on the CPU and GPU. You always get way lower FPS in the PhysX maps than the standard ones. When you remove the PPU, that GPU has to take that over. For games like UT3, SLI will be the Minimum hardware requirement for PhysX.

              What kind of FPS are you getting now on PhysX maps with your 8800 and PPU? You know it can only be lower with out the PPU as you will likely lose 50% of that or more.

                Could that work on PS3?
