    Abstract: A method and an apparatus for updating graphics resource usage according to a stream of graphics commands atomically submitted to a graphics processing unit (GPU) are described. The stream of graphics commands may be received from a plurality of graphics APIs (application programming interfaces) by a graphics driver. Availability of graphics resources of the GPU may be monitored by the graphics driver for submitting the stream of graphics commands. A single notification from the GPU may indicate that all graphics commands submitted to the GPU have been executed for updating a usage of graphics resources associated with the executed graphics commands.
