Minimum System Requirements:

Pentium II CPU 300Mhz or equivalent 64MB RAM Memory Microsoft Windows (98, Me, NT4, 2000, or XP) DirectX 8.1 or later Windows Media Player 6.4 or later D3D video card with at least 8MB and the latest drivers

However, for the best possible experience in Chi3D Worlds we recommend the following:

Pentium IV CPU 800Mhz or better 128MB Memory / 256MB Memory for XP Microsoft Windows 98, Me, 2000, or XP 500MB free disk space DirectX 8.1 or later Windows Media Player 9 or later 3D accelerated video card with at least 64MB and the latest drivers

Software Requirements

In order to run in Direct3D accelerated mode, Chi3D Worlds requires at least DirectX 7.0 or later. If you do not have at least DirectX 7.0 on your computer and want to run in Direct3D mode, you should download and install the latest DirectX from Microsoft. OpenGL and software modes do not require DirectX.

Good performance in Direct3D and OpenGL modes also requires that you have the latest drivers installed for your 3D video-card. See our video-troubleshooting page for help with video drivers.

Internet Connection

You must have an active connection to the Internet in order to access Chi3D Worlds. Additionally, if you are running behind a firewall, Chi3D Worlds must be properly configured to run behind a firewall (click here for more information.)

Hard Disk Space

The initial install of Chi3D Worlds will take less than 5MB of space on your hard disk. However, as you travel in Chi3D Worlds, the objects you encounter are cached to disk for faster loading on your next visit. This can require a substantial amount of additional disk space. We recommend that you have at least 300MB free on your hard disk at all times for best performance.
