Abstract
Vertical synchronization (v-sync) in prior art prevents video tearing artifacts by keeping the video pipeline synchronized with the monitor. Such technique keeps the frame rate of the rendering engine equal to monitor's refresh rate. However, it suffers from two substantial shortcomings: performance limitations and input lag, both of which are critical in real-time applications such as video games and professional applications (e.g. 3D CAD). The different embodiments of present invention, termed virtual vertical-synchronization (Virtual v-sync), eliminate tearing artifacts, while solving the shortfall of performance by shortening or dropping undisplayed frames, and solving the input lags by removing frame blocking. Any frame rate is achievable, independently of the monitor refresh. Two additional uses of the virtual vertical-synchronization are cloud gaming improvement and power consumption control.
