TWEAK YOUR OWN!
You can leave the "on battery" option alone to conserve power, but
for "plugged in", pick "never". Next click "change advanced power settings". Here you have a whole bunch of options. See Figure 4.
For the "plugged in" options, use these settings:
Hard disk: turn off hard disk after: Never
Internet explorer: JavaScript timer frequency: Maximum
performance
Desktop background settings: slide show: Paused
Wireless adapter settings: power saving mode: Maximum
performance
Sleep: sleep after: Never; Hibernate after: Never
Intel CPCC energy efficiency settings: Enable energy efficient
operation: Disabled; Energy efficiency aggressiveness: 0%.
USB settings: USB selective suspend setting: Disabled
Graphics settings: graphics power plan: Maximum performance
Processor power management: Minimum processor state:
100%; Maximum processor state: 100%. If you do nothing else,
do this. It prevents the processor from throttling down when it's not
active. It can take a long time to throttle back up when an audio
process needs the juice.
Display: Turn display off after: Never
Multimedia: When sharing media: Prevent
idling to sleep; when playing video:
Optimize video quality
Here's a very advanced extra. Under "processor power management", you probably don't
see an option called "processor performance
core parking min cores". This is a feature which
allows Windows to turn off ("park") cores in a
multicore processor to save power. This can affect performance because it takes time for the
core to un-park. It's turned on by default, and
the option to change it is usually hidden, but you
can just turn it off, which I'll tell you how to do.
Warning, this is advanced stuff. Do not
attempt this if you're not comfortable with advanced configuration and paying attention to
detail. Even then, attempt at your own risk!
Make sure the "high performance" scheme
is selected in power options (you probably
just did this).
Click the Windows Start button, and in the
search window, type "cmd", which should
pull up "Command Prompt". Right-click on
this and pick "run as administrator".
A command line window will appear.
Type the following on one line:
powercfg -setacvalueindex scheme_
current sub_processor bc5038f7-23e04960-96da-33abaf5935ec 100
Hit Enter and then type:
powercfg -setactive scheme_current

This will turn off core parking, but it won't give you the new
option in your power options window.

Advanced optimization: OTHER options

Besides power options, there are quite a few more things
you can do to boost audio performance. Try these on for size:
Processor scheduling: Search for "performance" in the control
panel. Click on "adjust the appearance and performance of Windows" and go to the Advanced tab. Under "choose how to allocate processor resources" select "background services". Note: this
is usually the better setting because most audio processing is done
in the background, but there are times when it actually harms performance, so if you change this and notice a dip, change it back.
USB hub power: Search for "device manager" in control
panel, go to Device Manager, scroll down and click on "Universal Serial Bus controllers". There should be one or more
items called "USB root hub" or similar (look for the words "root
hub"). On those, right-click and pick "properties". Click on the
"power management" tab and uncheck "Allow the computer to
turn off this device to save power".
While you're in Device Manager, you can
disable devices you don't need, but be careful!
Don't disable a device if you don't know what
it is. In general, don't disable devices in the IDE
ATA/ATAPI Controllers, Processors, System Devices, Universal Serial Bus Controllers, or Computer groups. Some devices that are usually safe
to disable are batteries, Bluetooth, imaging,
network adapters (wireless especially), sensors,
and sound, video, and game controllers. Obviously you don't want to disable devices you're
using (the network adapter, for example).
Don't actually uninstall device drivers
unless they're for hardware that no longer
exists in your system. Instead just right-click
and pick "disable".
Drive properties: In windows explorer, rightclick on your hard drive, pick "properties" and
uncheck "compress this drive to save space"
and "allow files on this drive to have contents
indexed in addition to file properties" (See
Figure 5). If you have an extra drive that's
just for storage and isn't getting accessed by
audio software, you can go ahead and use
"compress this drive" to save some space.
Graphics card: Some graphics cards
have a throttle setting much like the
processor setting, which allows the card
to throttle down when not in demand. This
can cause the same problem of lag when it
throttles back up. If you can, turn this setting
off in your graphics card settings.
