Nvidia has revealed new technology that eliminates screen-tear from PC gaming forever. Dubbed "G-Sync", it's a combination of a monitor upgrade working in concert with software that is exclusively available only from Nvidia's Kepler line of graphics cards. It's a phenomenal achievement that drew praise from three of the most celebrated names in video game technology: id software's John Carmack, Epic's Tim Sweeney and DICE's Johan Andersson, all of whom were on stage at Nvidia's reveal event to sing the praises of the new tech.A fundamental problem facing gaming is that the monitor operates on a clock that is separate and distinct from your console or PC. On a typical 60Hz display, the screen refreshes every 16.66ms. If the games machine has a frame ready, it can synchronise with the display, but it absolutely needs to have the next frame ready in the next 16.67ms period, otherwise it will have to wait another 16.67ms for the next refresh. That's the fundamental problem with games that run with v-sync - if that time interval isn't met, judder creeps in.
The alternative right now is to pump frames out to the display as soon as they are ready, mid-refresh. This causes a phenomenon we simply can't abide: screen-tear.
