If you use the VMware Blast display protocol or the PCoIP display protocol when using 3D applications in a remote desktop, mouse performance improves when you enable the relative mouse feature.

In most circumstances, if you are using applications that do not require 3D rendering, Horizon Client transmits information about mouse pointer movements by using absolute coordinates. Using absolute coordinates, the client renders the mouse movements locally, which improves performance, especially if you are outside the corporate network.

For work that requires using graphics-intensive applications, such as AutoCAD, or for playing 3D video games, you can improve mouse performance by enabling the relative mouse feature, which uses relative, rather than absolute, coordinates.

When the relative mouse feature is enabled, performance might be slow if you are outside the corporate network, on a WAN.


A Horizon administrator must turn on 3D rendering for the desktop pool. For information about pool settings and the options available for 3D rendering, see the Setting Up Virtual Desktops in Horizon or Setting Up Published Desktops and Applications in Horizon document.


  1. Start Horizon Client and log in to the server.
  2. Right-click the remote desktop and select VMware Blast or PCoIP.
  3. Connect to the remote desktop.
  4. From the Settings dialog box, toggle the Enable Relative Mouse option to on.
    To disable the relative mouse feature, toggle the Enable Relative Mouse option to off.
    Note: If you use Horizon Client in windowed mode rather than full-screen mode and the relative mouse feature is enabled, you might not be able to move the mouse pointer to the Horizon Client menu options or move the pointer outside of the Horizon Client window. To resolve this situation, press Ctrl+Alt.
