In one embodiment, the graphics load of a physical desktop is measured by a remoting agent installed on the physical desktop. The graphics load can be used as an estimate of the load that would be created by a deployed virtual desktop. The remoting agent on the physical desktop mimics host operations that are necessary to direct graphics data to a remote site. The remoting agent also measures the graphics load incurred by the host operations to determine a capacity of a virtual desktop system prior to deployment of the virtual desktop system. ## Claims ### Claim 1 A computer-implemented method comprising: mimicking, by a remoting agent installed on a computing device, host operations of a host remoting agent that are necessary to direct graphics data to a client at a remote site, wherein the computing device includes a graphics unit to simulate the host operations locally at the computing device without directing the graphics data to the client at the remote site; measuring, by the remoting agent, a graphics load incurred by the host operations at the computing device to determine a capacity of a virtual desktop system prior to deployment of the virtual desktop system on a host system, wherein the host system includes a set of one or more servers to run one or more virtual machines, and wherein at least one of the one or more virtual machines provides a virtual desktop for the client at the remote site;
