nVidia G-Sync

This looks interesting.

Not entirely sure what this will mean, but if it does what it claims then this could change things.

So dynamically alters the monitors refresh rate to match that of the GPU output? Noice.

Neil79 · 18 Oct 2013 at 18:25

Need to see it in person first

Does that mean no tearing ever at all? So smooth as vsync off but no tearing like vsync on

Jokester · 18 Oct 2013 at 18:38

Certainly sounds like it will.

The G-Sync module will control drive LCD displays with timings fluctuating all over the place. As soon as the framebuffer is complete it will update the screen, eliminating tearing and stutter. After seeing some demos I can't be anything other then impressed. Very smooth stutter and tearing free framerates on the monitor. G-Sync is going to included into monitors from ASUS, BenQ, Philips and ViewSonic.

That vid is great. I think I've found a reason to retire my monitor.

Predicted here? Ryan, Linus and Rein have seen it with their own eyes and have all said something along the lines of game changing, big difference, the future of gaming.

Gratz to nvidia for this conference, absolutely smashed it!

I'm dubious. For someone like me, who isn't bothered by screen tearing - no, not even slightly - how is this game changing? Or is there more to it?

Power saving ;D

Not much benefit then if you don't like Vsync and don't mind tearing.

Why wasn't this part of the DVI / HDMI / DisplayPort standard? It seems obvious that your display refresh should match your source. Just like TVs which don't match Blu-ray frame rate.

Shame some of the other big players like Dell and Samsung aren't on-board.

Nice one Neil and fantastic vid with a clear explanation of how it works. I struggled to hear it on Linux cam

So you're not fussed about tearing which means you prefer that over input lag (and some people are vice versa). They're offering a solution which eliminates the problem with v-sync on and v-sync off.

Primarily though it's improving visual quality which is always a good thing

I am quite interested in this technology and look forward to testing out monitors that use 'G-Sync'. Maybe it's getting late and it has been a long day, but one thing I am wondering... If you are running a monitor at a high refresh rate (for example 144Hz) it is advantageous even if you aren't getting 144fps. Even at significantly lower frame rates there is a specific 'fluid' or 'connected' feeling to that 144Hz refresh rate. You'll know this feeling as you move your mouse and look around the game world - it's purely related to the refresh rate and has nothing specifically to do with input lag. It can't be replicated on a 60Hz monitor even if it has zero input lag, so my issue is this - will 'G-sync' take away this connected feeling if it has to lower the refresh rate at lower frame rates? Some people really like this feeling (me included) even if it doesn't technically make a difference to my performance in a game title. Seems like it isn't all pros and no cons if so.

Not if it works as it should.

I always wondered how 30 fps on console games doesn't feel anywhere near as bad as 30 fps in PC games. Certain degree of fluidity there, I think this could deliver that "feel".

I jumped on 120hz early on, and will look to do the same with this. Will wait to see what screens come out first though.

Prob get another Asus next time.

Rofflay · 18 Oct 2013 at 21:37

120hz IPS with Nvidia G-SYNC please

I just based my earlier thoughts on running 120Hz monitors (at 60fps) and also running the same monitor at 60Hz. Despite the frame rate remaining the same, there was a 'connected feeling' at 120Hz that wasn't there at 60Hz and that can't be replicated by ANY 60Hz LCD. But I suppose the story changes when the whole process is streamlined in the way that G-Sync proposes. I think if it does do what it promises to do and can deliver supremely low latency without frame delays, stuttering, tearing and all that then it will make for a very fluid experience.

pgi947 · 18 Oct 2013 at 22:11

Will be keeping a close eye on this, sounds right up my street.

Will likely go asus after having such a good experience with my vg236h.

smilertoo · 18 Oct 2013 at 22:21

I'll have a long wait, i couldn't go back to 1920x1080 low res.

Dash RipRock · 18 Oct 2013 at 23:01

Taken from the nvidia FAQ on g-sync....

Q: What are the resolutions of G-SYNC monitors?
A: NVIDIA G-SYNC enabled monitors will be available in a variety of resolutions from 1920x1080, to 2560x1440 to 4Kx2K. The Asus VG248QE NVIDIA G-SYNC enabled monitor has a max resolution of 1920x1080.

This would indicate that ips/60 hz panels will be using it,so no need for the image quality/colour guys to discount this tech.hell I may be tempted to drop back to a 60hz ips display with unlocked frame rates and no tearing.Ive wondered for years why this couldn't be done with LCD displays (CRT's obviously would have not been the best with a dynamic refresh

) it seems so obvious although granted it's probably not a simple task.

Gazb · 19 Oct 2013 at 01:58

As I said in the other thread about this, isn't this something that screen/monitor manufacturers could implement thdm selves like a kind of adaptive vsync rather than requiring a proprietry nvidia add in card to do..?
