Now, it may help some, it may not. Not everyone's system is the same, so this guide is a small "at your own risk" type of deal. Yes, he has helped me and other's on tweaking games but he is not a miracle worker, so don't expect anything to walk on water.
Also, I respect opinions and I do allow them here, but there is a difference between a honest, civil opinion and a rant/bash of the guide and the author. If you have something to say, comment or opinion, be it in a positive manner, not making a post a monkey with half a brain would make. Also, consider this before you go all gun-ho on the guide:
Oh noooo!....
The tweak guide points folks to a general optimization guide for Windows, and in that PDF it covers.... gasp..... Component STRESS Tools to make sure your hardware is actually stable and operating correctly.
Wonder if all the people that took a snip all over http://www.gamesas.com/index.php?/topic/1303107-extreme-component-testing-cpu-ram-gpu/page__view__findpost__p__19611751 are going to have another brain aneurysm at being told that maybe it's a good idea to test their equipment for proper operation before they make assumptions that something else (like a piece of software) is the only cause or the root cause.
Anyhoo...
