Abstract: A method for improving graphics performance is provided. The method includes: determining whether a current frame rendered into a frame buffer is a first frame in a first vertical synchronization (VSYNC) period defined by a first VSYNC signal; and pre-rendering a first next frame into the frame buffer in the first VSYNC period when the current frame is the first frame, wherein the first next frame is a frame that is next to the first frame.

Abstract: A service model-oriented software system and an operation method of the present invention take a service module object as a basic component to drive the software system to run; support componentized software running and development, provide loose coupling, good openness and high security and is easy to be expanded. The software system includes a server-sided system architecture and a client-sided system architecture; the server-sided system architecture includes a service model factory component, a service model control engine and an activity service model component; the client-sided system architecture includes a client-sided control engine, a data object agent component and a view component. The software system and the operation method thereof lay a solid foundation for the development of the service-oriented software technology, provide solutions for the development of the computer software system in the cloud environment, and open new ideas and methods for the development and application of the software.
