what does that g-sync do
You did not read it.
Go read it again.
here you go matt, they didn't say it in the presentation, but the page on their website goes so far as to claim;
"G-SYNC’s elimination of input lag, tearing, and stutter delivers a stunning visual experience on any G-SYNC-enhanced monitor; one so stunning that you’ll never want to use a ‘normal’ monitor ever again."
Zero input lag with current technology is impossible. Getting it down to a level where it isn't noticeable in all games is still awesome though.
That's all good, but as i say i can achieve the same thing with the method i mentioned above.
i can achieve the same effect (reducing input lag) with setting the fps limit 1 below the monitors refresh rate. I do not experience any negative performance by doing this. This was my point. Nothing more, nothing less.
Cool story bro, but looks like Linus, Ryan and Rein disagree with you as I'm sure they've tried all methods under the sun and they still said this looks better than anything they've seen.
Show us a video of 30fps looking smooth?
I think the important part here is the variable refresh rate. Your method works fine if you have the grunt to remain that high - at the same time though certain games at a locked FPS will introduce mouse input lag (just like VSync).
If you look back at my posts, that's all ive ever said.
You really think this method they have will somehow make 30 fps smooth? It might work on higher fps but 30 fps is a big ask with vsync enabled.
If you can present anything what says im wrong and this method will reduce input lag further than the method im suggesting then fair enough.

Comment From Peter (me)
Ryan do you think it would be a good move for nVidia to expand on their current NVAPI to be even more in the direction of Mantle over time?

Ryan Shrout: Based on what these developers are saying, yes.
Never said otherwise either? I was adding it for clarification as it's otherwise open-ended.
Can't say for sure until my eyes see, but the video is fairly evident of its effects and PCper are working on some slow-mo footage which should help illustrate said effect.
I don't need to think this method will make 30fps smooth I know it will as Linus said so himself whilst recording it and many others said the same. Also it's not with vsync enabled it's their gsync technology that makes it possible.
If it makes games smooth at 30fps with no input lag then fair play i say. Any actual game footage or just that?
They showed games there as well apparently, should be some footage soon. Although you're watching it through a camera that can't record it properly and a monitor that doesn't display its effects correctly. It will be one of those things you need to test yourself, peoples perceptions of input lag and frame rate vary wildly, it's also down to what you've become accustomed to.
Ryan said Pcper are doing a hands on demo with it on Monday.
I can see it being a feature which could benefit in a few situations. For me though i would not describe it as game changing but we'll see what the feedback is like when it becomes available. As with all things it pays to keep an open mind rather than write something off completely before its been released.
