Aspects of the present disclosure relate to systems and methods configured to adjust the timing of frame scanout in response to fluctuations in the source frame rate of graphics content rendered by a processing unit. In certain implementations, a vertical blanking interval generated during scanout of frames from a frame buffer may be adjusted in response to detected changes in the frame rate at which the source content is generated. In certain implementations, rendered graphics may be streamed over a network for display in real-time on a remote device, and the scanout out of frames may be adjusted in order to better match the rate of compression and streaming to a variable frame rate of the source content.
