RDP Connection Configuration
Enable menu and window animations
Default: Checked
If you are using a slow connection, disabling this option will prevent the server from displaying menu and window animations.
Enable themes
Default: Checked
This determines whether themes are enabled.
Enable bitmap caching
Default: Unchecked
Selecting this option will cause bitmap data to be stored in local thin client memory once downloaded from the server. This will enable the thin client to display previously viewed graphics faster as it does not have to wait for the server to send the data again.
