I figure some people simply haven't seen the video....
* Updating BIOS can improve a PC's speed no end as it's the base of everything.
* Updating drivers/firmware/windows update improves reliability and performance (he should have told people to backup though).
* Disabling power management on USB in device manager can improve reliability.
* Setting the power settings in control panel to max makes absolute sense.
* Disabling Wifi during recording is a good idea
* Running latencymon is a really good idea to see if you PC's performance is up to scratch.
* Optimizing your ASIO buffers is a good idea.
Apart from one point (see my original post) all the "tweaks" are pretty much essential in the video...
Not covered in video...
* Antivirus should be optimized (as stated in previous post).
* Some Windows Services can reduce performance such as Windows search as it searches the hard drive.
* Task scheduler running during a recording can screw with things. The obvious example is running a defrag in the middle of a recording but there are other processes.
* Speedstep issues (might be OS specific but not in my case).
* A manual loopback test is generally a nice idea.
Pretty much none of these issues are not exclusive to a particular OS. None of them are not worth doing or are particularly complicated.
