A method for remotely provisioning resources for running a computer application is described. The method includes: causing, using one or more processing units, an initialization of a user interactive video portion of a computer application, the computer application being executed using a remote server; determining a runtime of a static video portion of the computer application and a time required to complete initialization of the user interactive portion using information provided by the remote server; and delaying a start time of displaying the static video portion when the runtime of the static video portion is shorter than the time required to complete the initialization of the user interactive portion. A device that is capable of performing the above method and a server are also described.

Start-up performance improvement for remote computer application

Novel solutions are provided for consistent Quality of Service in cloud gaming system that adaptively and dynamically compensate for poor network conditions by moderating rendered frame rates using frame rate capping to optimize for network latency savings (or surplus). In further embodiments, the encoding/sent frame rate to the client can also be managed in addition, or as an alternative to capping the rendered frame rates. The claimed embodiments not only maintain a constant Quality of Service (QoS) for the user, but may also be employed to leverage higher-performing networks to reduce operational costs.

Network adaptive latency reduction through frame rate control

A method for remotely provisioning resources for running a computer application is described. The method includes: receiving a request to execute a computer application using a virtual machine, the computer application having a static video portion and a user interactive video portion; while preparing the user interactive video portion, providing the static video portion to a user device remotely positioned relative to a server hosting the virtual machine; and streaming the user interactive video portion to the user device at an end of the static video portion. A start time of the static video portion is adjusted to accommodate a display time of the static video portion being different than a time required to prepare the user interactive video portion. A server and a system that are capable of performing the above method are also described.

Start-up performance improvement for remote application

A gaming system includes a network server and a gaming manager communicatively coupled to the network server. The gaming manager having a video control unit that starts a video game running remotely with a static video portion and a user interactive video portion and a video receiving unit, coupled to the video control unit, that receives the static video portion for local display while the user interactive video portion is being initialized remotely for subsequent local game play. The gaming system further includes a local user device, coupled to the gaming manager, that initially displays the static video portion and provides a user interface for the subsequent local game play following completion of remote initialization of the user interactive video portion. A method of managing a remote game is also provided.

A method for network cloud resource generation, including creating a template virtual machine. The method includes creating an instantiation of a virtual machine for an end user by cloning the template, and loading an application executed by the virtual machine. The method includes accessing first information associated with the end user, and loading the first information in an instantiation of the application.

One embodiment of the present invention sets forth a method for pre-computing Z-values using an IGPU and, subsequently, conveying these Z-values to a DGPU. The graphics driver partitions the display into rectangular M-by-N tiles of pixels. For each tile, the graphics driver generates a quad geometry that encompasses the corresponding pixels. For each image frame, the graphics driver configures the IGPU to generate and down-sample a Z-buffer, creating a coarse Z-texture that contains a Z-value for each tile. The graphics driver transfers the coarse Z-texture to the system memory and configures the DGPU to apply the coarse Z-texture to the quad geometries, thereby generating a coarse Z-buffer in which the M-by-N pixels included in each tile are assigned the Z-value for the particular tile. Among other things, this technique enables the IGPU to pre-compute Z-values for the DGPU without straining the system memory bandwidth or defeating the Z-buffer compression techniques used by the DGPU.

Novel solutions are described herein for providing a consistent quality of service, latency-wise, for remote processing by managing the process queues in a processing server and temporarily pausing frame production and delivery to limit the lag experienced by a user in a client device. The claimed embodiments limit the latency (lag) experienced by a user by preventing the production rate of rendered frames at the server from significantly outperforming the decoding and display of the received frames in the client device and avoiding the resultant lag.

A method for switching, including initializing an instantiation of an application and performing graphics rendering to generate a plurality of rendered frames through execution of the application in order to generate a first video stream comprising the plurality of rendered frames. The method includes sequentially loading the plurality of rendered frames into one or more frame buffers, and determining when a first bitmap of a frame that is loaded into a corresponding frame buffer matches an application signature comprising a derivative of a master bitmap associated with a keyframe of the first video stream.

Embodiments of the present invention are directed to provide a method and system for automatically applying artificial limits to display resolutions in a computing system to improve performance. Embodiments are described herein that automatically limits the display resolution of an application executing in a discrete graphics processing unit operating from configurations with limited means of data transfer to the system memory. By automatically limiting the resolution in certain detected circumstances, the rate of generated graphics data may be dramatically increased. Another embodiment is also provided which allows for the automatic detection of an application's initialization and pro-actively limiting the user-selectable resolutions in which the output of the application may be displayed in to a maximum resolution calculated for optimal performance. The application's termination is also detected, whereupon a comprehensive list of supported resolutions becomes available.

The server based graphics processing techniques, describer herein, include loading a given instance of a guest shim layer and loading a given instance of a guest display device interface that calls back into the given instance of the guest shim layer, in response to loading the given instance of the guest shim layer, wherein the guest shim layer and the guest display device interface are executing under control of a virtual machine guest operating system. The given instance of the shim layer requests a communication channel between the given instance of the guest shim layer and a host-guest communication manager (D3D HGCM) service module from a host-guest communication manager (HGCM). In response to the request for the communication channel loading, the D3D HGCM service module is loaded and a communication channel between the given instance of the shim layer and the D3D HGCM service module is created by the HGCM. The given instance of the shim layer maps the graphics buffer memory space of a host D3D DDI binary executing under control of a host operating system. Thereafter, function calls are sent from the given instance of the guest shim layer through the communication channel to the D3D HGCM service module utilizing the graphics buffer memory space mapping.
