G-Sync, On or Off ?

I always seem to hear many pros and cons about G-sync and many varying opinions.

I would really like to know what the community thinks about it or even if you run it on your machine.

 

Dear Mr. Tanner,

For benchmarking, stress testing, GSYNC off. We want GSYNC off during benchmarking along with VSYNC off to make the GPU not cap the FPS and work at its hardest to see what the temps are like

for normal day to day usage, GSYNC On offcourse, why else did we buy a GSYNC capable laptop/screen?

GSYNC helps by eliminating screen tearing/stuttering when the FPS dips below the screen refresh rate.

while this may not be THAT beneficial with say, a current game or a not so demanding game as the FPS may never drop below the screen refresh rate, it will be a great feature for future/more demanding games when the current GPUs cannot handle max settings at a refresh rate that is higher than the screen refresh rate.

To summarize all this, I always Keep GSYNC on unless I am benchmarking. G!v3 me t3h sm00thn3$$

 

Very good information, and I agree. It is always so satisfying to run a game without G-sync, then with and see such a noticeable difference in gameplay, for the better!

 

I find it interesting to compare desktop vs laptop. Laptop is worse than the desktop equivalent. It's basically freesync with Nvidia branding. I've had the XB271HK for a while now and am used to it's awesome GSync performance. It really feels super smooth especially with sli. When my Clevo first arrived I have to admit I was a little bit disappointed in how it performed. Not as tight, and still left occassional tears in a lot of games. Still really good obviously, but it's interesting that the difference is so large. My friend noticed it too when he switched to desktop.

Not to mention the Clevos at least have had a ton of GSync issues with it not working etc...

That said, I always leave it on. No idea why I'd want it off except like Phoenix said for stress testing and benchmarking.

Have you seen the Acer XB272-HDR and Asus PG27UQ? Those things are gonna be awesome and will really need that GSync lol.

 

also note, when enabling G-SYNC, I set VSYNC to FAST, this doesn't cap the FPS to the screen refresh rate

FAST Sync however is not available for SLI so one should set VSYNC to On (Smooth) for SLI systems

 

That is VERY good to know! Most cons or complaints I hear is the FPS capping.

 

Be smart....be like Phoenix....

 

Wait, how does that help? Fast sync letting the fps go over 60 say. Doesn't that still add input lag? It's probably better than VSync on but that's why I cap the fps.

It's really not that hard to just have like rivatuner automatically cap your fps. Then games are capped at 59 and you get the best of both.

 

Watch this video, maybe you'll change your mind:

 

It seems from what I've read this actually isn't that good unless your getting double your monitor refresh rate. That's pretty hard at 144Hz or 4K. If you can double it though fast sync would basically be the best of both worlds. Still doesn't seem better than capping the fps though in most situations.

Edit: Fast Sync is also bad for frame spacing.

 

Do you run G-sync ?

 

Yeah, did you get to see my post at the beginning about mobile vs desktop GSync?

Edit: Oh I meant capping the fps with GSync. Capping without is bad.

 

Off always

 

Why? I would like to hear from the side of someone who runs it off.

 

I Understant. It seems almost like a double edge sword in a sense of low frames, compared to better tear handling. Although, around 60 FPS does not seem bad IMO

Edit - This will probably trigger a lot of people

 

Capping it at 59.9 works with Rivatuner. Feels good. It's really really good at a higher refresh rate. I was using 140 to cap a 144Hz monitor and it is super awesome.

 

Mostly because I play games like Dota2 and CSGO. Where the fps is always 200+ , that adds that extra bit of smoothness to the game. Anytjing less and it feels noticebaly slow.

 

As my next gaming laptop will most definitely have G-Sync, I'll overclock the display to 63Hz, use RivaTuner to cap the fps to 60, turn V-Sync off and G-Sync on.
This will ensure, for one, a smooth experience with G-Sync, and a less taxed GPU (lower temperatures) in games where hitting 60fps is a piece of cake.

I like G-Sync. I like it on my Acer Predator X-34 at 90Hz refresh. It's night and day difference with and without. Pretty much anything over 40FPS up to your maximum LCD refresh is smooth as butta with G-sync on and no tearing or anything crazy.

 

It seems most people will turn off or are against it when wanting to run anything over 60 FPS, which is understandable.

 

Yes, so in this case, it seems you would rather have speed instead of smooth gameplay. Do you notice the tearing much at those high of frames?

 

I use G Sync on my G sync enabled monitors and Fast sync on my non G sync screens. I enjoy G sync just a bit more as it's behavior seems a bit more consistent across the widest range of FPS fluctuations.

I will only buy G sync monitors from here on out ... at 80+ FPS? It's just too good ....

;-)

 

Have you tried G-sync and Fast sync on the monitors?

 

I don't see any reason to turn it off at all. I mean it helps greatly with 30-60FPS range, and gets even more silky smooth if yo have a 60Hz+ LCD. My LCD runs at 90Hz, and with my 980 Ti and 3440x1440 resolution, most demanding games won't get close to 90.

 

Nope. None at all. Frame rate never drops under .

 

As much as I want to keep it on and I tried to keep it on GSync + Fast Sync.. it may be the drivers or the game but I've had instances where its running fine then it bugs out and frames go 80-90fps. I remember playing Doom a few days ago and it was running at 90s fps (non Vulken) then I disabled GSync and boom it went to 120-180fps lol.. so for now I keep it disabled but the feature is nice to have when it works.

 

I used Fast Sync for a few months when using a 60hz screen ... it was very smooth, like V Sync but with almost no perceptible input lag. Once I upgraded that screen to a 144hz screen (still no G sync), I found that just using V Sync was not at all bothersome as most of my games play at 100+ FPS.

I also have an Acer 1440p G Sync panel that I use exclusively with G Sync. When using G Sync, I never run any sort of driver based syncing, be it V Sync, Fast Sync or otherwise ... as I think this sort of conflicts with having the G Sync module in the monitor functioning. Not sure of the source but I've read on occasion that one should always turn V Sync (and by extension Fast Sync) off when using a G Sync panel.

My 1440p G Sync screen is also generally around 100 to 144FPS in all games as well and I just haven't experienced anything so responsive, fluid and down right CRT like in it's screen rendering as G Sync at those frame rates.

Were I limited to playing in the 50 to 60FPS range and while still using a G Sync enabled panel? I would still use the G Sync option as I find it's more consistently smooth than V Sync and without the lag and still better than Fast Sync. If I were playing in the 50 to 60FPS range on a NON G Sync monitor? I would then use Fast Sync as I feel it is far better (no lag) than standard V Sync.

My main concern is keeping the GPU power on tap to push 1440p at 100+ FPS across all titles I play. Once that becomes an issue, I will have to upgrade the GPU(s) ... LOL ...

 

When it was running at the 120-180 did you have an tearing issues?

 

Pretty sure if looked closely there are tearing but with its hardly noticeable on my end, but it could be the fact that one feels faster in response that I prefer it over the other.. GSync may be smoother but it could be input lag or response rate that I prefer it disabled.

 

Yes, for your gameplay I does not sound like you really think you would need it.

 

G-Sync causes gameplay problems at Fullscreen for me. 30fps with it on and V-Sync turned off. G-Sync is kinda gimmicky in my opinion.

 

You need to turn V-sync on in order for G-sync to work. Preferably best to turn it on in Nvidia Control Panel. When you activated the G-sync check mark in control panel it used to turn on V-sync automatically as well, but now it doesn't. If you turn it on in control panel leave V-sync off in game, and vice versa.

 

I wish it still did automatically, since this issue could have been avoided. Although I am interested to see if this helps his issue.

 

Some driver releases do this with Gsync too. They goose around half the refresh rate of the panel. Check with some other drivers too to be sure this isn't what's happening to you.

 

This might be a stupid question but how do I know if g-sync is enabled on my laptop? I have a g-sync 120hz monitor but don't know if it's on or not. Lol excuse my ignorance.

Right click on your desktop.
Click the nVidia Control Panel
under Display it should say Setup Gsync and it should say Enabled

 

download pendulum demo: http://www.nvidia.com/coolstuff/demos#!/g-sync

You should be able to hear the difference.

 

I can't stand tearing, it kills immersion for me. After seeing G-Sync first hand I want one.

 

Is G-Sync more useful for low FPS settings for example 40fps at 4K or high FPS settings such as 120fps at 1080P? Which causes more screen tearing?

 

In all situations. It eliminates tearing that can happen at any FPS.

 

It's more useful at lower FPS, at higher FPS you can use fast sync.
