Intended for all owners of dual-core processors, 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.

仔细一看TscSync.zip，好像是指所有的双核，都能用TscSync.zip。

俺尝试了，不过不知道有没有优化，感觉不出来

双核OP可以用吗？？

一般使用还是跑分？

这是超频网上转的：

AMD于近日发布了其双核处理器性能提升软件，名为Dual-Core Optimiser。这是针对Chimpzilla双核服务的首次升级，据悉，大量的软件和BIOS升级将会在7月出现。

　　对于那些拥有双核处理器的用户，AMD Dual-Core Optimizer可以绕过Windows的API，直接使用RDTSC指令，从而使得在游戏等应用上有性能提升。

　　这个工具可以保持两个核心并行工作，并且减少视频处理时性能分配的不均，或者改善别的因时序分配问题造成的性能损失。

没有测试么? :lol:

从 http://www.tweakguides.com/ 转来的,从这段里看，只是修正那些没使用windows api而直接用rdtsc指令取时间的游戏用的,没提到和反超线程有关.应该只对少数游戏有效吧.

AMD Dual Core Optimizer Released
2 July 2006

AMD has released a new Dual Core Optimizer utility. This is not the same as the previous CPU drivers they have released; apparently it's designed to improve performance in certain games on dual core CPUs. This is because some games use RDTSC timing rather than the native Windows timing method, and this can cause problems with dual core CPUs. To understand more about this, read this Microsoft MSDN Article and this Microsoft KB Article. I'm not certain how many games are doing this, or which particular games, but it looks like it may be a few.

To test it out, I installed it on my X2 4400+ and after a reboot I noticed that it has added a new startup item called amd_dc_opt.exe. Fortunately this file is only 104 bytes so it adds nothing at all to startup RAM usage. Then I ran 3DMark06 just to get an indication of the general performance impact - my score was near identical, up a few points from 4260 to 4264. I then tested out Need for Speed: Most Wanted, a game which I know has some odd issues with dual core CPUs and usually requires manually setting processor affinity to only one core to work. This time it seemed to work without any problems. I tried Oblivion but didn't see any noticeable performance difference.

In general, if you run any AMD dual/multi core CPU and use your machine for gaming then I would recommend that you install this application. It appears to do no harm whatsoever, does not use up any significant background resources, and as there are a range of games which apparently use RDTSC, it will help prevent potential problems and might improve performance as well. Note, you don't need to install any other AMD drivers for this to work, and in general I recommend against installing additional AMD CPU drivers.

Update: This utility only appears to officially be for AMD FX and X2 CPUs, and doesn't appear to work on other AMD dual core CPUs.

由于时间的问题，只跑了PI，没有什么长进

这上面不是说都基本没有进步吗？可能主要是为了避免发生退步的情况出现。

也许和前一段时间X2，传言中的X2游戏不平衡，双核反而会导致游戏性能下降有关。推出一个双核优化补丁，减少出类似问题的几率。

文件都说了对部分程序和游戏有效

应该是部分程序和游戏， X2有可能出问题。什么问题呢？

就是：如果程序没有调用Win的API，而是直接调用rdtsc指令， X2就可能出问题或有危机。

明明是推出一个bug补丁，减少出问题的几率。避免退步的机会，也等于有所进步

INQ这次是完全颠倒。

COD 2 MP有一点提升，大概是4%。

手头的一些其他游戏都有一点下降。

上次装了CPU驱动,结果进不去系统了,不知道是主板驱动不兼容还是自身软件有问题.
