Technologies related to intermediary graphics rendition are generally described. In some examples, one or more devices in a local network may be equipped to serve as real-time graphics rendering intermediary computing devices for clients in the local network. A graphics rendering manager for the local network may collect graphics processing capability information of the devices in a local network, and may select computing device(s) in the local network to serve as intermediary computing device(s). The graphics rendering manager may interact with a system controller at a server or datacenter to direct compositing flow(s) to the selected computing device(s), responsive to system controller requests to initiate intermediary graphics rendering for clients in the local network.
