2. If this this is about increasing the efficiency of display out put, would it not be better to add a second card to achieve better desired effect?
3. How can we delineate between lag due to refresh rate of whatever Gsync is trying to fix at the monitor level vs lag due to game engine problems etc?
4.How "smart" is gsync in detecting wide range of inputs from two, three or four Nvidia cards for a surround set up?
5. Is this still in beta stage with conceptual endorsements from all these devs? And, what the heck doe sit have to do with devs anyway; game engine compatibility. etc?
I am not expert in display technology, but my limited understanding is that the quality of display screen has a lot more impact on viewing experience than any synchronization of imperceptible ms lag
1: the monitor needs to be able to accept a variable refresh rate, and the video card needs to be able to supply it. This means the monitor needs additional hardware, and it means the video card needs to be able to supply that signal. Whether the video card needs specific hardware or just a specialized driver, I don't know.
2. This isn't about GPU power, it's about removing the monitor as a bottleneck. Right now, if you have a GTX 780, and your minimum framerate is 45fps, you can spend a lot of money on a second video card, you can turn your graphics settings down, or you can spend 100 extra on a monitor that can display 45fps without lag tearing or judder, and still display higher framerates when they're available. This isn't just about getting to 60fps anymore, because you get a smooth transition all the way from 30fps to 144fps(or whatever your panel supports).
3: hypothetically, there won't be any lag due to refresh rate. The monitor will refresh whenever the frame is done rendering, and that's that. You can have one frame take 15ms to render, and the next take 20, and then a third take 18, and that's how long it would take to display that frame.
4: no idea.
5: no idea, but it doesn't sound like it cares about the game engine, just frametime.Edited by TranquilTempest - 10/19/13 at 11:15am
