    How will this affect us non developer users? Will it any effect on Physx/game performance? I know some have complained about Cuda 3.2.1?

    if you check in main physx folder you will see there are various skd packets from 2.3.1 to 2.8.3 and 2.8.3 is the latest., btw 9.10.0514 is the latest:)

    But yea cuda4 won't be only because of new physx - if it makes it this soon at all., like you saw it yourself there are various c++ to cuda optimizations and newer/better parallel gpu communication techniques.. probably or mostly visible by tesla stations.

    I'd like to see a new version of PhysX that shares the workload between the CPU and GPU because at the moment the CPU is too weak to handle it (or, maybe, the code itself is not properly optimised) and using the GPU means there's less horsepower to run the game itself. Most PhysX games I've played where the effects have been noticeable, such as Batman: Arkham Asylum, have had very erratic framerates and I've always wondered if a more streamlined version of PhysX that uses both the CPU and GPU would alleviate that.

    yea that's just it, the thing is a unoptimized mess.. This sdk 3.0 "will have" SSE2 instructions and "better" multi core awareness, but i doubt it will be that faster though..
    Well If they optimize it to the max, then im sure we won't need a separate phsyx gpu at all, but we all know that will never happen or nv loses profit..

    And what comes first quality product or huge profits by milking us customers with half ass products, making us believe we need that extra stuff (separate gpu for phsyx)?

    really i lol every time i see someone with let's say 580gtx for gpu and then they go and shove in a 280gtx just for physx, seriously what a waste of gpu and its power..Selling that 280gtx would be a much better choice.
