Tomb Raider: Underworld Demo

README file                            <28/10/2008>              Version 1.1

Part 1: Things You Should Know

Please read through the DirectX section of this document. This section has information that is vital to successfully running the Tomb Raider: Underworld Demo on your system.

1.1              DirectX

This game is optimised for Microsoft's DirectX 9.0c.   In order for you to play the game, you must have DirectX 9.0c compliant drivers for your video card and sound card.  Please note that although DirectX 9.0c is installed with the game, your video and sound card drivers will not be upgraded to DirectX 9.0c drivers. 

You will need to obtain the latest DirectX 9.0c drivers from the manufacturer or PC supplier. These drivers cannot be supplied by Eidos.

1.2              Memory and Performance

While the game will run fine with the minimum specification memory listed for your Operating System, your playing experience will be smoother if you have more.

Regardless of how much memory you have, you can maximize your available memory and increase the overall performance of the game engine by doing the following:

q       Closing any open windows

q       Shutting down all other programs, including menu-bar programs like any `instant messaging` programs

q       Defragmenting your hard drive

Eidos recommends that you have no other programs running at all while playing the Tomb Raider: Underworld Demo. Other programs, including system utilities and screen savers can cause system degradation when playing games and may conflict with the game for system resources, potentially resulting in instability and crashes.

1.3               Known Issues

q       Ensure you are running latest drivers from nVidia and ATI.

q       Low end nVidia hardware users may notice a slight stutter when first entering a location. This is a known issue with the current release of drivers (178.13). This should be addressed in an upcoming driver release.

To download drivers, you need to contact your computer manufacturer (or motherboard manufacturer if your computer is custom built).
