There's a frame-rate threshold where the G-Sync effect begins to falter. It'll change from person to person, and from game to game, but across our testing, we found the sweet spot to be between 50-60fps in fast action games. Continual fluctuations beneath that were noticeable and while the overall presentation is preferable to v-sync, it still looked and felt not quite right. Owing to the nigh-on infinite combination of different PC components in any given unit, the onus will be on the user to gauge his quality settings effectively to hit the window, and equally importantly, the developer should aim for a consistent performance level across the game. It's no use tweaking your settings for optimal gameplay, only to find that the next level of the title incurs a much heavier GPU load. And if our G-Sync testing has taught us anything, it's that - within reason - consistent frame-rates are more important than the fastest possible rendering in any given situation.
Overall, G-Sync is a hardware triumph, but the quest for a consistent, enjoyable gameplay experience is far from over. By eliminating the video artefacts, G-Sync lays bare the underlying problems of wildly variable gameplay frame-rates in PC gaming and highlights the problems of inconsistent input latency. If the hardware issue is now fixed, what's required now are software solutions to make the most of this exceptional technology
