Recording medium having programs to display frames stored therein, game display method for executing frame-by-frame display, and game displaying apparatus

Abstract

Display change cycle of images having a different processing load is coincident with the load. After completion of the generation of a frame image, the generation of a vertical synchronization signal is awaited, and a frame buffer is changed. In synchronization with the change of the frame buffer, the generation of a next frame image is started. A generation time of the immediately preceding frame image is measured using one frame cycle as a unit. The measured value is used as a predicted value of the generation time of a frame image to be generated. The measured value is thus determined as it is as a value of the game progression degree that the next frame image should have. When the game flows have been determined, respective polygons constituting each of a group of objects constituting the next frame image are calculated with respect to the position and orientation after lapse of the frame period corresponding to the number of the game progression degree value. Based on the calculation results, image data representing the figures that shows the respective polygons are stored in the frame buffer.
