AMD Dual-Core Optimizer

AMD Dual-Core Optimizer is a piece of software that allegedly improves gaming performance by bypassing Windows' API in some specific situations.
This utility helps that software access the RDTSC instruction directly, in order to correct the Time Stamp Counter on separate cores. It effectively keeps both cores working in parallel and reduces the differing video performance effects, or any other flaws that relate to timing situations in dual-core or upcoming multicore processors.

    Sounds more like bugfixes than an optimizer...

    It doesn't really improve performance at all. It is mainly gonna fix the stutters, long pauses, and some crashes in programs (games) that are not coded for dual processor function. A lot of the time the code will be waiting for something to complete that actually ran on the other core. It is not programed to look so it waits, and waits, and waits, etc.....

    This "Optimizer" simply makes the timing stamps in the code line up so you don't end up with out of order processing because of the affinity problem. Mo more power or speed :)

    I thought this allowed the CPUs to run in unisen for programs that are not SMP capable.

    Are you thinking of the suspected "reverse hyper-threading" supposedly in the socket AM2 chips?

    This little exe only corrects timing issues.
    I've been running it for 3 or 4 days and it helps, but my bench marks are all identical.

    Here's the release notes :

    Ah, the steely-eyed missile man explains this so that I finally understand. Thank you for putting in less technical terms. All the news sites I read seemed to all more or less regurgitate another site's news. But finally, an explanation for the layman.

    So it is just a minor fix,

    Well I didn't run a whole suite of benches, just ran 3D Mark 05 3 times, once before minor tweaking, once after tweaking, and again after installing this update.

    The lowest bench was with these optimizers, but only by like 10 points :P

    Question is... should I have installed the AMD CPU Drivers first, or so you not need the CPU drivers unless youw ant to use cool n Quiet?

    Well the optimizer is just a small exe loaded in registry startup.

    I installed the drivers after. They are the latest CPU drivers and work fine wether you run CnQ or not.

    Can't see why not to load em since they are the latest and greatest.
