Embodiments of the present invention monitor and dynamically allocate computing resources to game sessions running within a game service. A game service provides a remote gaming environments to which users connect over a wide area network, such as the internet. A game session runs a single instance of a game title. The game session runs the video game code responsible for creating the playing experience for the users. Various characteristics of the game session may be monitored and used to allocate computing resources. Usage of computing resources, such as central processing unit (“CPU”) may be monitored directly. In another embodiment, the number of players connected to the game session is monitored and computing resources are allocated dynamically as the number of players increases or decreases.
