Since Windows 95, a growing list of OS optimizations have been used by audio professionals to achieve low-latency, glitch-free DAW performance. Still to this day, there are numerous background tasks in Windows that degrade audio performance, causing clicks, pops and crashes. Before we jump into the updated list, it's important to understand the importance of quality hardware. A computer is the centerpiece of a game audio studio and by far the most important device. Before jumping into the tweaks, meet our Sponsor:

Windows Audio Tweaks

If a PC is the centerpiece of your game audio studio, it will likely benefit from a performance and speed boost. Audio software, virtual instruments and plugins can cripple a computer and cause unwanted down-time. Ideally, you shouldn't even have anti-virus software on your DAW. Even when it's "off", it's still running in the background, and taking up RAM. Wireless LAN adapters are more problematic than wired ones, and should be disabled completely. Don't just "disconnect from the network" but rather, find them and disable them. It's also important to disable any power-saving features in the computer's CMOS/UEFI. This must accessed in the boot menu and varies from system to system. Put on the detective hat and get in there. The following tweaks are a good place to start. Windows 10 is the most stable OS version but many of these will work with Windows 7 as well as Windows 8. Always backup before optimizing your system.

Adjust the PC for high performance

The CPU may must be running at full speed all of the time:

1. Go to: Control Panel>Power Options

2. Choose "High Performance"

3. Then click the "Change plan settings" button. Make sure both power options are set to "Never".

Disable system sounds

System notification sounds can interrupt audio so it's important to disable them:

1. Go to control panel and select "Sound"

2. Go to the sounds tab

3. Under sounds scheme, select "No sounds"

4. Click "Apply" then, "OK"

Disable User Account Control (UAC)

This helps alleviate and prevent installation and registration issues. To disable UAC, click the start button. In the Search Box type UAC and press ENTER.

In the UAC window, slide the slider down to 'never notify' and press OK

Go to "Advanced system settings" and then the "Advanced" tab

Click on "Settings.." under Performance to bring up the "Performance Options" window.

Go to the "Advanced" tab and set processor scheduling as "Background Services"

Click "Apply" then "OK"

Disable Windows Firewall, anti-virus and spyware software

These should all be disabled to ensure that no interferences occur during audio recording or playback and to ensure that maximum resources are available. To remain secure while your firewall and antivirus disabled, it is advisable to temporarily disconnect from any internet connections when working with audio. This will also make sure that no network adapters are conflicting with any audio.

Disable Visual effects

The visual features in Windows 10 can use resources that could otherwise help to improve audio performance. As a start, it is good idea to disable some of the visual features by doing the following:

Bring back up the "Performance Options" window by following step 3 above and clicking on the "Visual Effects" tab and selecting "custom".

Untick: "Animate windows when minimising and maximising" to help prevent glitches when minimising and maximising. You can also experiment with disabling other visual effects in the custom list to see how they improve audio performance.

Once finished, press "OK"

Disable USB Power Management

This helps prevent power issues with devices that are powered by USB.

1. Open Control Panel, then click on Device Manager.

2. Open the Universal Serial Bus Controllers menu.

3. Right click on the USB Root Hub in the menu and choose Properties

4. Go to the Power Management tab and un-check the the box to 'allow the computer to turn off'

5. Repeat this for each of the USB Root Hub's that show up in device manager

Enabling Write Cache

1. This helps alleviate poor hard drive performance. In Device Manager open the Disk Drives menu.

2. For all of your hard drives, right click on the drive name and select Properties

3. Go to the Policies tab and check the boxes to "Enable write caching" and "Turn off Windows write-cache buffer flushing"

(For external hard drives, change the option from "optimize for quick removal" to "optimize for performance")

(For internal drives, make sure "enable write caching" and "turn of Windows write-cache buffering" are both checked.

For external drives, just check "better performance" is selected

BIOS

Every computer has a BIOS and it's important to make sure yours is up to date. Check with the manufacturer to ensure you have the latest and greatest firmware update. Once inside your computers BIOS, look for "Intel Speedstep", EIST, or "AMD Cool n' Quiet", and disable it. These tend to downshift your CPU clock cycles to conserve electricity and can interfere with DAW processes on a PC and can degrade performance.

Advanced Tweaks

For those seeking to squeeze even more performance from their Game Audio Workstation, advanced tweaks will disable even more useless services that run in the background and drain system resources. Head over to Black Vipers list of Service Configurations and get to work. This site has been around for ages with detailed info on each Windows OS. Although it's geared toward hardcore gamers, your audio workstation will benefit greatly.
