In conjunction with the release of the new GeForce GTX 980 Ti graphics card today, NVIDIA is making a handful of other announcements around the GeForce brand. The most dramatic of the announcements center around the company's variable refresh monitor technology called G-Sync. I assume that any of you reading this are already intimately familiar with what G-Sync is, but if not, check out this story that dives into how it compares with AMD's rival tech called FreeSync.
First, NVIDIA is announcing a set of seven new G-Sync ready monitors that will be available this summer and fall from ASUS and Acer.
Many of these displays offer configurations of panels we haven't yet seen in a G-Sync display. Take the Acer X34 for example: this 34-in monitor falls into the 21:9 aspect ratio form factor, with a curved screen and a 3440×1440 resolution. The refresh rate will peak at 75 Hz while also offering the color consistency and viewing angles of an IPS screen. This is the first 21:9, the first 34×14 and the first curved monitor to support G-Sync, and with a 75 Hz maximum refresh it should provide a solid gaming experience. ASUS has a similar model, the PG34Q, though it peaks at a refresh rate of 60 Hz.
ASUS will be updating the wildly popular ROG Swift PG278Q display with the PG279Q, another 27-in monitor with a 2560×1440 resolution. Only this time it will run at 144 Hz with an IPS screen rather than TN, again resulting in improved color clarity, viewing angles and lower eye strain.
Those of you on the look out for 4K panels with G-Sync support will be happy to find IPS iterations of that configuration but still will peak at 60 Hz refresh – as much a limitation of DisplayPort as anything else though.
Another technology addition for G-Sync with the 352-series (353-series, sorry!) driver released today is support for windowed mode variable refresh.
By working some magic with the DWM (Desktop Window Manager), NVIDIA was able to allow for VRR to operate without requiring a game to be in full screen mode. For gamers that like to play windowed or borderless windowed while using secondary or large displays for other side activities, this is a going to a great addition to the G-Sync portfolio.
Finally, after much harassment and public shaming, NVIDIA is finally going to allow users the choice to enable or disable V-Sync when your game render rate exceeds the maximum refresh rate of the G-Sync monitor it is attached to.
One of the complaints about G-Sync has been that it is restrictive on the high side of the VRR window for its monitors. While FreeSync allowed you to selectively enable or disable V-Sync when your frame rate goes above the maximum refresh rate, G-Sync was forcing users into a V-Sync enabled state. The reasoning from NVIDIA was that allowing for horizontal tearing of any kind with G-Sync enabled would ruin the experience and/or damage the technology's reputation. But now, while the default will still be to keep V-Sync on, gamers will be able to manually set the V-Sync mode to off with a G-Sync monitor.
Why is this useful? Many gamers believe that a drawback to V-Sync enabled gaming is the added latency of waiting for a monitor to refresh before drawing a frame that might be ready to be shown to the user immediately. G-Sync fixes this from frame rates of 1 FPS to the maximum refresh of the G-Sync monitor (144 FPS, 75 FPS, 60 FPS) but now rather than be stuck with tear-free, but latency-added V-Sync when gaming over the max refresh, you'll be able to play with tearing on the screen, but lower input latency. This could be especially useful for gamers using 60 Hz G-Sync monitors with 4K resolutions.
Oh, actually one more thing: you'll now be able to enable ULMB (ultra low motion blur) mode in the driver as well without requiring entry into your display's OSD.
NVIDIA is also officially announcing G-Sync for notebooks at Computex. More on that in this story!
