    it's always good practise to offload work away from your cpu.

    your graphics card has got a dedicated chip designed just to run physx - use it for games that are physx-enabled! let your cpu do other things.

    This could be a stupid question but how can you get your graphics card to take the load off your cpu?

    In general? It's up to how the app/game and drivers are coded.

    There's not really much you can do.

    nvidia graphics cards have a 'physX' chip, which is used by some games to enable physics effects, for example shooting a barrel and having it roll away naturally and convincingly.

    ati cards don't have this chip, so if a game needs to do some physx calculations, this work has to be done by the cpu, which is already busy running the os and the rest of the game.

    not that many games actually use physx, so it's not such a huge deal.

    i've not bought an nvidia gpu for some time, but i expect the drivers enable on-card physx processing by default.

    gpu's also do a lot of video en/decoding these days, reducing the cpu load whilst watching dvds for example.

    Thanks for making this clear for me :)
