D. Known Configuration Issues
Visit the official Web site for the latest updates and support information: www.unrealtournament3.com.

Certain keys on non-English keyboards do not function correctly: On some non-English keyboards, certain keys do not work as expected. In other words, what appears when you press the key is not what is printed on the key. To fix this problem, remap any problem keys. 

Sever passwords are not case sensitive.

If you're having problems connecting to other players while running a co-op campaign or a server: You need to open port 7777, and that should allow other players to connect.

Windows Vista Users: We recommend installing the Vista hotfix (http://support.microsoft.com/kb/940105) which fixes virtual address space usage on Vista.

Hotfix for SLI customers running DirectX 10 applications: Please go to http://support.microsoft.com/kb/936710. This hotfix resolves occurrences of low frame rates on some DirectX 10 applications when SLI is enabled. Performance improvements will vary depending on the application and the graphics driver version.

If you are using third party applications like Xfire: You may experience a performance drop. Disabling these applications will possibly improve your performance. For support please go to http://www.xfire.com.

E. Known Graphics Issues
Video Settings: The default settings chosen for most systems for Unreal Tournament 3 are very conservative, prioritizing performance over visual acuity. You should experiment with your video settings to find the best balance for your PC.

If you're experiencing blurry graphics, lots of jagged edges, and your system meets or exceeds our recommended system specs - it's possible that the automatic configuration may need to be adjusted.

You can override these detected settings by going to the Advanced Video options in Unreal Tournament 3. You can access these settings by:
1. Select Settings from the Main menu
2. Select Video from the Settings menu
3. Select the Advanced button on the Video Settings screen

Screen Percentage: The most likely reason for an overall low visual quality. If set to 50, for instance, and UT3 was running at 1280x960 - the actual image quality would be comparable to 640x480. Set the slider to “100” to force the game's resolution to the resolution your game’s fullest possible resolution. 

Texture Detail: Determines the quality of the textures applied to the world. 

World Detail: Determines the complexity of the geometry used to render the world.

Some issues with NVIDIA graphics cards cause the game to stop: To run Unreal Tournament 3 with certain NVIDIA cards, you must install the NVIDIA ForceWare 163.71 driver, or a later driver. To install the 163.71 or later driver, go to the www.nvidia.com/drivers website. If you do not install the 163.71 driver or a later driver, at some point the game might stop and your progress will be lost.

For other issues with NVIDIA graphics cards and Windows Vista (including flickering), go to the www.nvidia.com/object/windows_vista_hotfixes.html website.

If you are experiencing meshes flickering with NVIDIA graphics cards and Windows Vista please reboot your machine – this is an NVIDIA driver issue.

Hotfixes for GeForce customers running Windows Vista: Please go to http://support.microsoft.com/kb/938194 and http://support.microsoft.com/kb/938979 - these hotfixes improve the compatibility and reliability of Windows Vista. It can be downloaded from this link or from Windows Update.

Some issues with NVIDIA 7900 graphics cards cause the game to stop: If users are getting crashes creating rendering resources (pixel shaders, index buffers, textures etc) on NVIDIA cards with low operating system memory (1GB or less), follow these steps for a workaround:

1. If AVG anti-virus software is installed, it needs to be uninstalled. This program causes resource conflicts with drivers. Be sure to restart the system after removing AVG.
2. In UTGame/Config/UTEngine.ini, set bInitializeShadersOnDemand=True.
3. Run the game again.

Some issues with ATI graphics cards cause the game to stop: To run Unreal Tournament 3 for Radeon 9x00 cards, we recommend installing the ATI Catalyst driver revision 7.8 from the www.amd.com website. If you do not install the revision 7.8 driver from the website, at some point the game might stop and your progress will be lost. For newer cards we recommend installing ATI Catalyst driver revision 7.9.

When using the game editor, windows can get rendered behind viewports: To fix this problem, do not use the game editor with a floating taskbar.

Graphics Card Drivers and Manufacturers
Be sure that you have installed the latest driver for your graphics card. Many video issues will be resolved simply by updating your graphics card's drivers. Unreal Tournament 3 may not properly detect some older graphics cards because their video drivers are not DirectX 9.0c compliant. Contact your graphics card manufacturer for updated drivers, or install the latest reference drivers for your graphics card chipset. Note that many reference drivers are not supported by the chipset manufacturer. Listed below are some common graphics card manufacturer Web sites.

F. Known Hardware Issues
Some issues with AMD processors cause the game to stop: To run Unreal Tournament 3 with certain AMD processors, you must either install the AMD Processor Driver for Windows XP and Windows Server 2003 Version (x86 and x64 exe) 1.3.2.16 or get the latest driver for your brand of processor from the www.amd.com website. If you do not install this driver or the latest driver from the website, at some point the game will stop and your progress will be lost.

G. General Audio Issues
Audio stops at game start in Windows Vista: When the game is started on certain computers running Windows Vista, the audio stops. To fix this problem, install the latest driver for your sound card.

Audio occasionally crashes on startup in Windows Vista: In case of audio/hardware/driver issues, please run the game with –nosound in the command line to determine if your audio drivers are causing the crash. If the game does not crash with the –nosound command, please upgrade your audio drivers.

Possible issues with X-Fi Sound Blaster Cards: There may be possible crashes on x64 exe systems and/or machines with more than 2GB of RAM. Please be sure you are using the latest drivers from the http://us.creative.com/support/downloads/ website.

The Unreal Tournament 3 does not support more than 2 channel audio on cards without OpenAL drivers: The game only outputs 5.1 if the “Hardware OpenAL” checkbox is ticked and the sound card has OpenAL drivers.

Audio during the campaign mission objective screens may occasionally cut out: This is during the campaign mission loading screens and is only on certain PC models.

Some issues with C Media or other sound drivers cause the game to stop while playing a movie: Follow these steps for a workaround -
1.	Open UTGame/Config/UTEngine.ini
2.	Set PumpWindowMessagesWhenRenderThreadStalled=True instead of False.
