Default G-Sync in the house! - 01-16-2014, 21:57 | posts: 895 | Location: UK

It arrived early, wasn't expecting it till tomorrow.

I've just fired up BF4. It is A W E S O M E!

It runs ~90fps so you might not think GSync would benefit me so much but you'd be wrong, it's a wonderful experience, night and day compared to the old monitor running without VSYNC.

I was running a Viewsonic 120hz 1680x1050 before, now it's 1080p but the reduction in FPS feels like a huge increase, the lack of tearing makes the picture crystal clear and buttery smooth.

Yes it might be expensive and people have slagged off this ASUS monitor but in actual fact, it has a much better picture than the Viewsonic that I came from.

Believe the hype, GSync is the real deal!

I think the answer is zero unless your frame drops below the refresh rate of your monitor.

so it benefits u even at 90 fps? it very useful for 120hz gamers like u me and others. Gsync is winner, but it need reduced price.

You apparently haven't looked into it. There is no locked framerate when running GSync. The benefit of it is that you can run the game, and whatever framerate it is capable of running at, the refresh rate of the MONITOR is synced to whatever the GPU is able to output, so that each frame is rendered. VSync locks the game framerate to your monitor refresh rate.

There is a big difference. You get input latency that is virtually the same as V-Sync off. That means, no more "floaty" mouse and stuff.

However, there are some limitations with G-Sync: it doesn't work in Windowed mode. There are games out there that don't run in proper fullscreen mode, but rather in "borderless fullscreen window" mode. "Runescape" is an example. Those games do not work with G-Sync. This also means that people who like to run their games in this "fake fullscreen" mode, will not be able to use G-Sync.

Another limitation is that input lag increases again if the game runs at too high a framerate. On a 144Hz monitor, if you get near 144FPS, you'll get the same input lag as with V-Sync. So games that cannot be framerate capped and run too fast will also not benefit. I dunno if the driver frame limiter works with G-Sync. If yes, it might be used to fix the problem by capping to something like 140FPS.

That's cool, no tearing, no input lag and we can even cap the framerate to 30 and have a smooth experience. That's the way it's meant to be played.

But if you have a super computer that can give you a steady framerate, lets say 60, and if input lag is not important i would say that V-Sync still does its job perfectly.

30 FPS with G-Sync looks exactly the same as 30 FPS on a 60Hz or 120Hz with V-Sync. That's because 30 is a divisor of 60 and 120.

So 30FPS is not going to magically become smooth. Things start to appear as very smooth somewhere near 45FPS though (I suppose this varies from person to person.) With 31FPS to 59FPS though, there's uneven frame doubling on 60/120Hz monitors because these values are not divisors of 60 or 120. This manifests as stutter (running 59FPS on 60Hz for example, results in a small stutter every 1 second, lowering FPS further introduces more stutters per second.) G-Sync fixes that.

Note that these stutters due to lower FPS than refresh rate are there even with V-Sync disabled. So it's not just people who usually use V-Sync that benefit from G-Sync.

Btw, BenQ announced new "G" monitors that already replace the just released "Z" models. Somewhere in Q1 2014, the XL2420G and XL2720G will be released, that will have G-Sync. So maybe it's best to hold on before buying a new monitor.

I use a G sync monitor as well, and after playing with it i will never buy a monitor without g sync on it ever again, its pure awesome

Btw does anyone got a link to download that g sync "show off" demo with the pendulum clock ? Would like to check it out

Because as he says, on 144Hz it's blurry mess compared to 120Hz lightboost.
And http://www.testufo.com/#test=framerates confirms it.
Too bad you can't test it with GSync, so you see difference.

But frame pacing is nice, tho minor upgrade to 120Hz screen anyway.
If you had 60Hz till now then it's night and day for you. Wonder what would you say if you had side by side comparison of 120Hz LB vs 144Hz GSync.

Good read for this topic of G-sync. Part 1 introduces what G-sync does and part 2 touches on the input lag and light boost topics.

As I said, I had a 120hz monitor before, it's a big upgrage.

I can and have compared 120hz LB and G-Sync because G-Sync monitors can do ULBM.

ULBM is fine and nice if you never drop below 120fps but if you can't do that, G-Sync is better and clearer because of the lack of tearing.

The monitor will automatically switch between ULBM and G-Sync so you can run ULBM at the desktop and G-Sync in games which seems like the best setup at the moment.

What he is probably experiencing is not 'smooth'-ness. He most likely is benefiting from from the lack of input lag. It wont look any different, sure, but if you ever set a game to use 1/2 refresh rate vsync on a 60hz monitor you know it feel like there is a whole 1 second delay.

Which arguably could be called smoothness. But it will not look any different, 30fps is going to look like 30fps, and 60fps is still going to look better, which I'm assuming is where the miscommunication comes in.

ULBM on desktop has close to no value as it reduces pixel persistence (faster transition from one displayed frame to another) and desktop is mostly static.
Maybe for movies, if there are any faster than 30fps or if played with player which calculated additional frames by shortening motion vectors.

But while I use LB in games, I do not use it on desktop, as it's color, brightness/gamma and contrast does not match properly calibrated screen.
And benefit of fast transition on mostly static desktop is so low that I prefer better color.

As for G-Sync vs ULBM vs LB in games: LB allows you to reduce pixel persistence (transition time from frame to frame) allowing you to see new image faster as it's not mixed with old image.

As you can see on Blurbusters tests even 144Hz screens blur last 4~5 frames together unless LB is in effect. That is why I question this "the lack of tearing makes the picture crystal clear and buttery smooth"
As it's hardly "Crystal Clear" without LB/ULBM and part of "butter smooth" is "Blurry transition".

And is reason why, I would like to see side by side comparison of LB vs GSync. As seeing separate images clearly has for me higher value than reducing frame variance from up to 8ms (120Hz) to virtual 0ms (GSync).

Fine if you can maintain 120fps and you can handle the noticeable reduction of image quality with LB. Otherwise, G-sync is much better because of the lack of tearing, that is what makes the image clearer, it has nothing to do with frame variance.
