A third option is to use your headset exclusively for Xeno voice chat, and leave your speakers for game
audio without mixing the two in your sound card’s control panel. To do this, connect the microphone plug
on your headset to the microphone jack on your Killer Xeno, and the headphone plug on your headset to
the audio-out jack on the Killer Xeno. Remember – this option will leave the voice chat audio exclusively on
the Killer Xeno.
Setting the Lag and Latency Reduction (LLR) mode
Two Lag and Latency Reduction (LLR) modes are available on the Killer Xeno:
• Game Mode — optimizes the Killer Xeno for online gaming by allowing the Killer Xeno to bypass the
Windows Network Stack, prioritize game data, and free up system resources.
Configuring the Killer Xeno
The Killer Xeno ships with the best configuration for all online games. Unless you encounter a technical
problem and are advised by a support specialist to change any of these settings, it is recommended to
keep the default settings.
Note: Other installed network cards may not function properly with LLR Game Mode selected. It is
recommended that you disable all other network cards if you want to use LLR Game Mode.
• Application Mode — operates the Killer Xeno as an optimized, “normal” network card. Use this mode
to run programs that require access to the Windows Network Stack (such as VPN clients), or for
troubleshooting applications that are not functioning in LLR Game Mode.
Note: The default settings are optimized to fight lag on your computer, resulting in smoother game play in
many online games. These effects are best noticed after repeated play in intense multiplayer gaming
sessions, such as big raids or combat in MMO or FPS games.
To set the LLR mode:
1. Right-click on the Killer Xeno tray icon.
2. Select the LLR mode.

Configuring Killer Bandwidth Control
Killer Bandwidth Control is a powerful feature that allows your computer to do more while you game.
By managing the bandwidth each online game uses, you can continue to game with less lag and
smoother online gameplay while listening to streaming music, downloading large files, using your favorite
voice chat application, or all of these.

To use Killer Bandwidth Control, set the following for your games and applications:
a. Locate the game or application whose priority you want to change.
• Priority
• Bandwidth
• Connection Settings
Note: Games and applications appear with the file name used by the Windows operating system.
These file names may be abbreviated. For example, World of Warcraft may be listed as WoW.exe;
Call of Duty 4 may be listed as CoD4.exe.
To configure Killer Bandwidth Control:
1. Right-click the Killer Xeno tray icon.
2. Select Bandwidth Control.
b. Select the priority for the game or application:
• 1 Game — use for most games
• 2 Realtime — use for applications such as voice chat or streaming music
• 3 Standard — use for lower-priority applications or applications you do not want to interfere with
your game.
3. Select the Priority tab and set the
priority settings for your games and
applications.
c. Set the Offload configuration for the game or application:
• Yes— the Killer Xeno offloads the network processing for the specific application. (For most games,
the default is Yes). This setting is recommended for game traffic only.
• No — the Killer Xeno does not offload network processing for the application.
4. Select the Bandwidth tab and set the Bandwidth settings for the games and applications you
Note: The Game Detect feature automatically identifies online game applications and sets these
as high priority (1 - Game). You can change these priority settings for your games and other
applications as desired.
want to modify.

a. Locate the game or application and set Download and Upload settings:
a. Click the Test button to launch your default web browser and start a bandwidth speed test.
• Unlimited — use for most games
b. After the test completes, write down the Download and Upload values, as shown in this example.
Other programs should be set to lower bandwidths than your game, depending on the total bandwidth
available. Try different settings for each program while you game, and make sure to monitor your lag.
Note: Do not assign more bandwidth to a program than you have available. This will impede the
performance of your online gaming experience.
5. Select the Settings tab and modify the connection settings for the games and applications you
want to modify.
c. Enter the Download and Upload values in the Download/Upload kb/s fields next to My Internet
Connection Speed.
Important: Be sure to enter the actual tested values for your broadband connection. Setting these
values too high causes Killer Bandwidth Control to assign too much bandwidth to programs, which
can impede your online gaming experience.
6. Click OK.
Configuring Killer Firewall
Killer Firewall protects your online gaming computer from intruders and unauthorized Internet access by
programs on your computer.
When enabled, Killer Firewall runs entirely on the Killer Xeno’s Network Processing Unit (NPU), allowing you
to disable any software firewalls that run in the Windows operating system on your computer. This keeps
your computer protected with less performance impact than traditional, software-based firewalls running on
your computer.
Killer Firewall protects your computer by notifying you each time traffic wants to come into your computer.
It does this by identifying programs that open ports to your Internet connection that are listening for data.
Any time a program on your computer wants to open a port to the Internet, and you have not asked it
to do so, Killer Firewall notifies you and asks your permission to open the port.
Note: You may not want to enable Killer Firewall if your computer is already protected by a firewall in your
home router or gateway.

To enable or disable Killer Firewall:
To change alert settings:
1. Right-click on the Xeno Killer Tray icon.
1. On the General tab, locate the Alerts section.
2. Select Xeno Firewall.
2. Select Exception alerts will be made:
• Per Application — use this setting to receive alerts when a program tries to access the network.
This is the simplest option; Killer Firewall notifies you only once when a program is requesting access.
• Per Individual Port — use this setting to receive alerts for every port that programs are trying to access.
This is a complex option; Killer Firewall notifies you multiple times if a program needs access to
multiple ports.
3. On the General tab, under Firewall, select the On button to enable Killer Firewall;
select the Off button to disable Killer Firewall.
Note: When Killer Firewall is enabled, alerts are also enabled automatically.
Adding Killer Firewall Exceptions
Each time Killer Firewall notifies you about a program that is requesting access to the Internet, it will ask you
if you would like to add this program as an exception to the firewall rules. If you select Yes, Killer Firewall
automatically adds that exception.
You may need to edit an exception occasionally, especially if you patch or reinstall a program and it then
requires a different port or protocol. If this occurs, edit Killer Firewall exceptions.
To edit Killer Firewall Exceptions:
1. On the General tab, under Exceptions, select the program name for which you want to edit
firewall settings.
2. Click Edit.
3. Edit the settings.
4. Click OK to save the settings and return to the Firewall screen.
Deleting Killer Firewall Exceptions
You typically need to delete a Killer Firewall exception after a program has changed, been patched,
or uninstalled from your computer.
To delete Killer Firewall exceptions:
Changing Alert Settings
1. On the General tab, under Exceptions, select the program name for which you want to delete
exception settings.
After Killer Firewall is enabled, alerts are enabled automatically.
2. Click Delete.
3. Click Yes when prompted to confirm the deletion and return to the Firewall screen
