The Nvidia G-Sync Thread

[bystander36]

I wouldn't say it is nothing like it. Just not as good. It is an attempt at removing tearing without stuttering issues when FPS are not maintained.

The two biggest issues I have with it is 1) it will lower visual quality and 2) what happens if the game is CPU bound and no matter how lower the settings are set, you cannot maintain 60 FPS?

Would love to see something like this gaming monitor monitor (VA panel) get the G-sync.

I've never noticed tearing in console games to be honest. Since the hardware is more or less "set", while a PC's hardware isn't, it's basically easier for developers to set a framerate target and meet it more often than not. Conversely, every PC is different so developers can't really set a framerate target there, and if you pass a certain level of performance you may get tearing with vsync off. So I don't really see why MS is bothering with this thing they're doing - it really isn't needed. IMHO anyway.

I assume this, on consoles at least, is either to make life a bit easier on the dev's, or to help cover up the occasional hickup.

Yeah, i could see that.

I do think one big problem with prior generation systems was that a lot of people would put their consoles in home entertainment areas where there was not enough air ventilation - this caused a TON of issues with x360's RROD and PS3 failures. From what I understand, both next gen systems are implementing ways to lower features dynamically if ambient temps become too high (which they definitely will if you put a console in an area without ventilation. The "average" consumer is probably oblivious to this). Maybe this is part of why this is happening? To lower GPU load at times when it's needed to prevent failures as was so common on the PS3 and x360. Just thinking out loud, but perhaps that's part of it as well - lowering graphical demand on the fly when it's needed to ensure failures don't happen like they did with prior gen systems.

 

[bystander36]

Yeah, that's quite true. All these new GPU's throttle to protect themselves, or at least dynamically over clock if it is safe to. This can definitely be used for that.

This sort of technology could also be a bit useful on PC's. It would require more than just scaling resolutions, but it could be the start of dynamic optimizations.

A1) It will not lower visual quality at all, at the same settings it will look identical but without tears and without visual stuttering. Gsync will dramatically improve visual quality its a pure win, there is no downside besides buying a new monitor.

A2) This is what Gsync is designed for. If you can already maintain a perfect 60 fps then gsync wont help much, what gsync makes possible is vsync quality in the 30-60 (or the 60-120) range without compromising the quality of the image (tearing) or stutter (vsync).

You have never noticed tearing on the consoles because they run with Vsync on. That is why the developers target either 30 or 60 fps but never anything in between, because the stuttering effect only occurs in between the magic figures. The fact the console hardware is fix does allow them to target a very precise performance level, but it causes enormous compromises on the developers part to get it that way, both in terms of visual quality and in terms of development time. Sometimes they would like the option to drop to 25 fps to get this one effect in that would really make a difference, and at that moment the player wouldn't notice so that is when gsync would be really good.

Mircosoft has nothing to do with gsync at all. It is needed, its sorely needed and you need to watch the videos explaining what it is and why it matters because its going to be huge and vsync will probably be gone completely in a decade. Its a major advancement.

I guess you didn't read the posts before mine. We were not talking about G-sync, but this new Microsoft solution which lowers resolution if a game drops below its target FPS and upscales the image.

Almost never for my part. GT5 had bad tearing and was sometimes not able to keep 60fps.

Anyway, I hope this D-Res thing doesn't mean that developers will get lazy when it comes to optimizing their games. But I suppose it won't really matter for me, since it seems to be an MS exclusive feature. I will probably get the PS4 (in a couple of years).

 

[Shmee]

I think it could be nice for some people, but seems like a gimmick to me, even more so than GPU physxl; I spent $1100 on this top end HP 30", and I don't intend to downgrade it anytime soon, or change it at all for that matter.

 

[BallaTheFeared]

What's the gimmick?

http://www.youtube.com/watch?v=Lg5TAUrtXxo&feature=player_detailpage#t=585

Should be clear as day what the advantage is. I haven't seen it personally irl, but the people who have praise it across the industry.

Have you seen it first hand Shemee?

 

[Shmee]

I understand the point in smoothness is important, but for a while at least, it's not usable for us with high end monitors. Even if/when it comes to IPS, I do not intend to upgrade this monitor for a while.

Hey I'm sure people used stone tools for awhile, even though bronze was available

True but that monitor he's using would be considered Iron

Is there a 60fps video of that demo around somewhere? Would probably see the difference more pronounced in that than in 30fps YouTube vids.

It might show some difference, but a 60 FPS video runs at 60hz, so you really can never appreciate the difference fully unless seen in person. G-sync removes the evenly spaced out refreshes in favor of updating when the GPU is ready. You can't see the difference unless seen on one of these monitors.

 

[terente]

This G-Sync is the best thing to happen to display tech since... sliced bread! I have a 30" Dell 3008WFP-HC that I will consider upgrading as soon as they release a kit for it.
Refresh rates should be a thing of the past as it was only needed for CRT and G-Sync tech should be embedded in all LCD displays by default.
Why don't LCD display controllers produced from this day on be made aware of G-Sync tech and then the G-Sync could come in form of a module with DVI/HDMI in's and out's? That would make it easy to be adopted or upgraded to. No need to open up an expensive LCD display and solder the module on it's motherboard.
Buy the LCD now, G-Sync module when you have the money or complete setup for it.

A gimmick? You can't be serious. Well, you obviously are, but that is a joke.

You think Tim Sweeny is just faking his reaction?

The only way to appreciate it is to see it in person. I guess that is why some have resorted to calling it a gimmick until proven otherwise.

 

[Face2Face]

I would hardly call G-Sync a gimmick. I thinks it's the best thing that has happened to monitors is a very long time. My only complaint is the upcoming selection.... I am not going from 1080p to 1080p - Just like I am not going from a quad-core to another quad-core next go round. When G-Sync offers a selection in the 1440P and up monitors, then I will be very interested. Nvidia deserves mad props for this IMO.

This thread should probably go in a dedicated monitor forum.
G-synch deserves that.Is it going to work with nice IPS monitors like mine or am I shut out?
Luckily you bumped it up from the last post back on the 6th or I would've missed it.

 

[BallaTheFeared]

This is the monitor forum, good effort though

Thank you.
Good luck getting the Mantle thread moved by the way.:thumbsup:

It's not like a dropped a mod request, just a suggestion.. I think the AMD cpu fans need the love

 

[Will Robinson]

That's considerate of you..perhaps a Mantle "super" thread,one for VC&G and another for the CPU forum with direct links for easy updates?
