[Geforce] NVIDIA announces the revolutionary G-SYNC - Page 78

So, a glitch NVidia needs to fix to prevent this as a selectable option in unsupported hardware.

I was playing BF3 with G-sync enabled. It honestly slowed down my frame rate than having it off all together.

Input/output delays due to display-syncing have absolutely nothing to do with their inherent delays from other aspects of hardware or computing.

Input-delaying strictly applied to display syncing in this discussion, since even if it would abstractly apply to un-synced low frequency of refresh monitors or a low fps (or other delays in computing), it's completely off topic and pointless to discuss it since vsync or no sync, or gsync or no sync at all, those are always there, nothing we can do about it, at least with these technologies here.

What actually is going on here is that NVIDIA claims to have the granularity on the DisplayPort's low latency but also the response of modern monitors, to 1) have the graphics card not wait at all for the monitor (that claim can be easily believed) but most interestingly 2) that the monitor hardware (via the help of the g-sync contraption) has the granularity to sync with the fps of the card without waiting at all (that last bit is what some people that understand vsync find hard to believe, but if we assume modern hardware has that granularity, it's easier to believe it).

PS. BTW, that thing has around 1 GB of memory on it, it's likely that the hardware is not directly capable of doing it perfectly but they also use some approximation/algorithmic adjusting, but it's likely not something that alters the wider concept of the thing, and it may not even be used yet as much, it may be a contingency for the future, for finer adjusting.

You are using a setting for which no hardware exists yet. I can totally understand it being a detriment if you don't have the actual hardware... Nvidia is going to tarnish it's reputation before it even comes out if they don't force a lock down on the setting. People will think "Oh, this is gysnc? I don't need a special monitor? Oh, it's gimping my fps? Trash!"

NV is EXTREMELY hush hush when ever asked about the on board memory. I'm guessing all the secret's to the universe are stashed in it.

Nvidia G-Sync: the end of screen-tear in PC gaming
Quote:
By extension, we can also foresee that this will be a problem for Nvidia too - if the perceptual difference between, say, 45fps and 52fps, is ironed out to a great extent by G-Sync, we wonder if there will be enough differentiation in the product line-up to make the more expensive offering worth the additional premium. What is needed here is more testing on the impact of frame-rate differences on the gameplay experience - G-Sync may solve tearing and stuttering issues, but it can't address input lag, which does tend to be impacted by lower frame-rates (though this too can be addressed to a certain extent by developers).

Basically saying, why the more expensive GPU that can maintain 60+ fps when a lower end GPU holding stead at 45fps looks remarkably similar.

Sure, the bench metrics would be different, but what really matters for gaming is the experience and perception of fluidity.

Just something to ponder.

The onboard memory probably improves the syncing. The monitor is likely low latency enough in the relevant operations to approach the syncing-without-lag result but it may not be there yet. But with some minor prediction on the end-point there, it may improve (dunno, pure speculation at this point obviously).

I could see AMD doing rom-chips for their GPU's and ondie on their APU's and at no extra cost!

NVIDIA G-SYNC is so smooth and so fast, that testers have found themselves overshooting and missing targets because of the input and display lag that they have subconsciously accounted for during their many years of gaming.

ITT; G-Sync will make you worse than you already are.

Derp!!! if nvidia is gonna have it as a option, I will try it for fun. With it enabled I did see less tearing than having vsync off, with the same benchmark. Still doesn't mean much but still interesting to try.

I have a sort-of reverse psychology about ASUS now. It's so restricted to it that it makes me dislike them for this "psychological blackmail". I want to wait for it to have options (and hopefully be an open standard) but it's too early..
