Note that the desktop sharing feature of Dimdim will adapt to the amount of bandwidth you have available. So higher the bandwidth, lower the lag and better the screen-cast. This performance will be further supported based on the profile that you choose to use for you screen-cast.

Dimdim supports three types of profiles for its screen-casting (Desktop and Application Share) feature.

1. High Bandwidth (T1/LAN setups)

                   This profile uses 24-bit high-quality screen-casts. This would be the profile which will most accurately represent the desktop you are trying to share.

2. Medium Bandwidth (DSL setups)

                   This profile also uses 24-bit high-quality screen-casts. However, we use a locally painted mouse cursor instead of the rich cursor that you see on your desktop. This means that even if your cursor changes its shape (say, to an hour glass), the change will not be reflected on the attendee side.

                   This will help reduce bandwidth consumption and would be suitable for a DSL quality bandwidth. The quality of the share itself will be the same as in case of High Bandwidth profile.

3. Low Bandwidth (Dial-Up setups)

                   This profile provides 8-bit screencasts. This profile is not suitable for sharing graphical content. However sharing primary text-based desktops or applications will have access to good quality output.

                   The advantage with this profile is heavily-reduced bandwidth consumption and hence snappier screencasts with very less (if any) lag.
