1. A computer implemented method of dynamically adjusting a frame buffer resolution, the method comprising:
calculating an average frame rate for rendering a plurality of previous frames
calculating a target scaling factor related to frame buffer resolution based upon the average frame rate;
based on the target scaling factor, determining plurality of current scaling factors for rendering a sequence of frames to a frame buffer, wherein the sequence of frames are to be rendered subsequent to the plurality of previous frames, wherein each current sc lin. factor corresponds to a frame of the sequence of frames, and wherein the plurality of current scaling factors vary incrementally to reach the target scaling factor; and
adjusting a resolution of a respective frame of the sequence of frames rendered to the frame buffer according to a corresponding current scaling factor.
