E. Configuration Issues

Known hardware and operating system configuration issues are listed in this section. For issues with specific 3D cards, see section F, "3D Card Issues."

For assistance with top performance issues, visit http://support.microsoft.com/?pr=gmsperf.

Performance may be poor after standby or suspend mode: If you manually or automatically put your computer on standby or suspend mode while playing the game, performance may be poor when you come out of standby or suspend mode and resume the game: music and sounds may not be heard, transitions may be choppy, or the game may hang. To resolve, restart the game.

Enable direct memory access (DMA) in your IDE controller on Windows 98 Second Edition and Windows Millennium Edition: When you enable DMA on your computer, you improve the game performance and stability. 

To enable DMA: 
1.	Close all programs that are running on your computer.

If your sound card also came with its own software for setting speaker settings, ensure that these settings are also correct.

F. 3D Card Issues

Halo only supports DirectX 9.0b-compliant video cards. It is good practice to always install the latest certified drivers for all of your hardware.

For assistance with top video issues, visit http://support.microsoft.com/?pr=gmsvideo.

ATI Radeon 9800 PRO 128: You may experience inconsistent graphic performance with textures if you set the Mipmap Detail Level in the ATI Direct3D Control Panel to any setting except High Quality.

NVIDIA Video Cards and FSAA Modes: You may experience difficulties running Halo using NVIDIA video cards in any of the FSAA modes. If you are having a problem, you should disable the FSAA mode for the NVIDIA video card.

Via Motherboard Chipsets: If you have a Via brand motherboard, you may need to update to the latest “4-in-1” motherboard chipset drivers to avoid crashes. 

G. 3D Card Drivers and Manufacturers

Make sure that you have the latest drivers from the manufacturer of your video card. Many video issues will be resolved if you install your video card's latest drivers. Halo may not properly detect some older video cards because their video drivers are not DirectX 9.0b-compliant. Contact your video card manufacturer for updated drivers, or install the latest reference drivers for your video board. Note that many reference drivers are not supported by the chipset manufacturer. Listed below are some common video card manufacturers' Web sites.

NOTE: Use Windows Update (http://windowsupdate.microsoft.com/) to ensure that you are using the latest drivers and have the latest updates to your operating system.

For specific video card drivers, visit the manufacturer’s web site.

H. Audio Troubleshooting

Check with your sound card manufacturer for the latest DirectX-compatible drivers.

Following are the known audio issues and workarounds:

Users running Windows 98Second Edition and Windows Me: You should run Windows Update to ensure that you have downloaded all critical updates as well as all the recommended updates. Otherwise, you may have sound problems such as the weapon volume shifting in and out. 

Aureal Vortex: The audio may not function with Aureal sound cards. To resolve this issue, turn off the hardware acceleration. From the Start menu, point to Settings, and then choose Control Panel. Double-click Sounds and Audio Devices and select the Audio tab. Click the Advanced button in the Sound Playback section and then click the Performance tab. Move the Hardware Acceleration slider to None and click Apply. 

Hercules Game Theater XP sound card in Windows 98Second Edition: Stuttering and sound distortion may occur using the Hercules Game Theater XP sound card and Windows 98 Second Edition. See “Enable direct memory access (DMA) in your IDE controller on Windows 98 Second Edition” in section E, “Configuration Issues.” 

Hercules Game Theater XP sound card in Windows XP Professional: The audio may not function correctly at all times with the Hercules Game Theater XP sounds card. For example, grenade sound effects may play too low. You should make sure you have installed the latest DirectX-compatible drivers for your sound card.

Realtek ALC650 sound card in Windows XP Home: Halo may not function correctly using the Realtek ALC650 sound card in Windows XP if you enable EAX sound in the game. 

Montego II Quadzilla sound card in Windows 2000: The audio may not function correctly at all times with the Montego II Quadzilla sound card. You should make sure you have installed the Montego II Quadzilla Windows NT 4.0 drivers. Information on installing the drivers is available from http://turtlebeach.com.

I. Additional Multiplayer Information

Network Settings

To insure the highest level of multiplayer game quality, you should specify your connection type in Network Settings. Not only does this setting determine the maximum number of players you can host on a game, but it also determines the amount of data that you will receive from other servers when you are connecting to a multiplayer game as a player. 

To specify your network settings:
1.	On the Halo main screen, click Settings.
2.	Click Network Setup. 
3.	Select the appropriate connection type.
4.	Click OK.

Direct IP Connection

You can join an Internet multiplayer game using a specific IP address for the host server. The host address can be a computer name or numerical IP address.

To join a game using Direct IP:
1.	On the Halo main screen, click Multiplayer.
2.	Click Direct IP under Join. 
3.	Enter the IP address for the host server.
4.	Enter a password (if required).
5.	Click Join to join the game. 
Notes: 
·	Halo remembers the last host address you typed in.
·	If there is no game at the specified IP address, then a “Connection Failed” dialog box is displayed. When you click OK, you are returned to the Multiplayer screen. Try entering the IP address again, using the steps above. If that doesn’t work, you should contact the person hosting the game to verify the IP address for the host server.

Checking for Updates

Each time you join or create an Internet multiplayer game, Halo automatically checks for the latest update on the Internet. A dialog box is displayed indicating that Halo is “checking for updates.” If there is an update available, your current game is shut down, the update is downloaded and installed, and the game is restarted. 

If you choose to cancel out of your update, then you are returned to the Multiplayer screen. The next time you attempt to join or create an Internet multiplayer game, the process starts all over again. If there is a Halo update available, you must allow the update to download and install if you wish to continue. If you wish to manually update your game, please visit http://www.microsoft.com/games/halo/default.asp.

J. Multiplayer Troubleshooting

This section describes the known multiplayer issues and workarounds.

Ports Used by the Game
Halo connects to the Internet on the following ports by default:
§	2302 (UDP)—Game host listens on this port
§	2303 (UDP)—Game client connects to host through this port
Halo will run from behind most routers and Network Address Translation (NAT) devices. If you have difficulty connecting from behind a router, you should consult your router documentation to ensure that the ports listed above are not blocked for your PC.

Halo checks for updates via HTTP in the same way a Web browser would. If you use Windows XP SP-1, Halo can use an auto-detectable proxy server on your network, but does not currently support manually-set proxies. If your network requires you to manually set your proxy server, please visit www.microsoft.com/games/halo to check for updates, which you can download manually. 

To check your proxy settings:
1.	Launch Internet Explorer
2.	From the Tools menu, click Internet Options.
3.	Click Connections.
4.	If you connect to the Internet manually, double-click on the appropriate connection in the list at the top. If you connect via a Local Area Network (LAN), click LAN Settings.
5.	Under Proxy server, verify that the settings are correct for proxy server that you or your network administrator has set up.

If you are connected to the Internet and can reach http://www.microsoft.com, for example, your proxy settings are correct.

In non-team games (such as Slayer), all vehicles are spawning in front of the Red Base: You must select two of each type of vehicle to ensure that one vehicle gets placed in both the Red Base and Blue Base. In non-team games, the default base is Red when vehicles are assigned. If there is only one type of vehicle spawned, then only the Red Base will be populated with vehicles.

Damage-confirmation beep: You may want turn off the damage-confirmation beep in multiplayer games. To do this, you must use the Debug Console. To activate the Debug Console, run Halo with the -console command prompt (see the Command Prompts section above), press ~ in the game to enable the Debug Console, and then type should_play_multiplayer_hit_sound 0.

Unable to join a Direct IP multiplayer game hosted behind a NAT device or router, or on an Internet Connection Sharing (ICS) Server in Windows 98 Second Edition, Windows Me, and Windows 2000: You need to join multiplayer games that are hosted behind a router or on an ICS server via the Gamespy Lobby.

Unable to join a multiplayer game with an Internet Connection Sharing (ICS) Client on Windows 2000 or Windows XP: You may have difficulty joining a multiplayer game if a person using a Windows 2000 or Windows XP ICS client has joined and exited that game before you attempt to join it.

Unable to browse for games on a local area network (LAN) on a machine with two network adaptors in Windows XP: You may not be able to browse for multiplayer games on a LAN if the two network connections are not configured correctly. The Internet must be configured on the first network connection, and the LAN needs to be configured on the second internet connection. For more information on configuring a network connection, click Start, and then click Help and Support. 

Microsoft Base Station MN500: Halo does not offer automatic NAT negotiation of UPnP devices such as the MN500. If you have difficulties connecting to games or hosting a server behind this device, you should manually set it to forward the required ports—2302 and 2303 (UDP) by default—to the IP address of the game computer behind the router.
