    i've seen a some videos of desktops (some are quite old) but can get the CPU PhysX work. and there are videos in youtube that allows ATI cards to run games and enables PhysX via CPU. so could the 2720QM+6990m do it, too?

    Here's a vid of a desktop(2600K+6870): ‪Alice Madness Returns: PhysX on CPU Test - ATI/AMD GPU PC 1080p‬‏ - YouTube

    *i really wanted to play Alice with PhysX, so i wondered: if desktops could do it? can the 2720QM/6990m do handle it, too?

    core2duo/5570: ‪Alice Madness Returns Gameplay - HD 5570‬‏ - YouTube (PhysX low)
    4890 PhysX: ‪Alice Madness Returns on HD 4890 + Physx via CPU‬‏ - YouTube (High)

    my point is, can i also run it with the m17xr3? :eek:

    How do you enable CPU PhysX? Is it a hack or something?

    CPU PhysX is enabled within games that allow it. There is no setting or hack for it. The current implementation under SDK 2.0 is unoptimized for x86 processors and will run like p*ss on any processor as it only uses one thread.

    On a lot of games it actually runs quite nicely on the cpu. Mafia II, Metro 2033, come to mind.

    If you consider playing Mafia II 22-25 FPS @ 1920x1080 'running quite nicely', than I'd that comment with a grain of salt. A GTX 260 using PhysX on the GPU is a few frames faster than that. In my mind, that is a fricken poor attempt at running PhysX on x87 instruction sets.
