For example:

Several other performance issues
Problem
There are many different causes that can result in bad performance.
Solution
The following settings can be used as a single option and also in combination.
Basics
-
The color depth should be the same on the server, the device, and in the session (best: 32 bit).
-
In the BIOS, set the VGA shared memory to 64 MB or more.
Optimizations for a LAN Environment
-
Under Sessions > RDP > RDP Global > Performance, edit the settings as follows:
-

-
If Windows Server 2012 R2 or lower or Windows 8.1 or lower is used: Under Sessions > RDP > RDP Global > Multimedia, activate Enable Video Redirection.
