Double Buffering
On some graphic cards drivers may have problems with OpenGL drawing. This may result in 100% CPU load. In this
case the issue may be resolved by enabling Double Buffering.
To do so, open Main Menu, choose Local Settings (General tab), then toggle Double Buffering and restart Client.
Restoring Broken Archive
DW Spectrum uses a specific directory on each network drive. However, sometimes archive is moved for various
reasons (ex, a hard drive was replaced, hard drive's letter was changed. etc), possibly resulting in a complete removal
of archive from the system.
DW Spectrum can easily restore the lost archive. To perform archive restoration:
1. Open the Server Settings.
2. Click on Reindex Archive.
3. The process can take a long time. Click Yes to proceed.
Restoration can be canceled in any moment.
If the window is closed, the restoration will continue running in the background.
The system can continue recording while the archive is being restored.
If Camera have been deleted, Users lose access to its footage. However index rebuild will make such footage available
again. See "Viewing Archive from Deleted Cameras" for details.
