Will the Nvidia G-Sync reinvent gaming, or vanish as a niche product?

Nvidia G-Sync reviewed: Will the new monitor tech reinvent gaming, or vanish as a niche product?    Science & Technology World Website

 

In October, Nvidia revealed its newmonitor synchronization technologydesigned to improve game experiences by synchronizing directly with the GPU rather than relying on standard timing systems. Dubbed G-Sync, the new method could revolutionize monitor technology — if it delivers as advertised. Now that the first reviews of G-Sync are in, what kind of real-world improvement do we see?

So far, the results are mixed — but early impressions are positive. G-Sync works by matching the monitor refresh rate directly with the GPU draw rate, ensuring that frames are displayed as they arrive, without tearing or stutter. In theory, this results in a much smoother overall experience.

With the technology in such early stages, there are still a number of quirks and limitations. The early kits Nvidia shipped out are compatible with just one Asus monitor. They rely on DisplayPort (no HDMI or DVI), and they don’t carry audio. Refresh rates are also limited to 144Hz, the practical limit of the monitor — though it’s worth noting that this is a panel limitation. Unlike most modern TVs, the panel refresh rates advertised on displays like the Asus VG248QE are true refresh rates, not interpolated ones. Anand believes that we’ll soon see IPS panels at 2560×1440, but for now the 1920×1080 TN-panel Asus is all there is to test with.

The results are rather interesting, and very game-dependent. In the six titles Anandtech played (Assassin’s Creed, Arkham Origins, Sleeping Dogs, Dota 2, Starcraft II, and BioShock Infinite), G-Sync improved AC:4, substantially improved Batman: AO, but ran Sleeping Dogs dramatically worse. Dota 2 and Starcraft II were both a wash and BioShock Infinite was a split case. At a 144Hz refresh rate, BioShock Infinite doesn’t stutter or tear much, period — but G-Sync does help resolve the visible issues that occur.

The verdict, therefore, is that while G-Sync doesn’t matter for every game, it can make a dramatic difference in certain titles, particularly if you’re upgrading from a 60Hz panel. Asus estimates that the VG248QE, which normally runs about $280, will go for $400 with a G-Sync kit built-in. That’s a substantial cost adder, particularly for a TN panel — Anandtech hopes that we’ll see the technology built into 2560×1440 displays, where it might also make more sense for FPS reasons. G-Sync works best in games where the frame rate hovers between 30 and 60 fps. Modern high-end cards have less trouble at 1920×1080, but take heavier hits at 2560×1440.

As for the long-term future of the technology, that remains an open question. The downside to G-Sync is that you’re effectively locked into a single display and Nvidia’s graphics cards. Obviously from Nvidia’s perspective, that’s a huge positive, but it also could limit multi-display gaming. Still, the technology is in its early stages, and all reports are that it can improve the overall gaming experience, at least some of the time. That’s a decent starting place for any new technology — we’ll see where it goes from here.
