is g sync worth it?

[owenkj]

from those who have experience using a gsync monitor would you say it is worth it?

if the gpu cant hold refresh rate or better in fps, gsync/freesync will not do anything

I thought It would help reduce the impact of small dips under 60? or am I wrong

That assumes the graphics card is always causing a drop in frame rates.
If it is a badly optimised game where no hardware upgrade can remedy it then gsync or freesync is needed.

Here is my experience so far with my Acer Predator X34P monitor which is nearing 2 years old.

So specs wise, this monitor is 3440 x 1440 @ 120Hz, IPS with G Sync and has a pixel response and input lag of 9ms (according to --> https://www.tomshardware.com/reviews/acer-predator-x34p-gaming-monitor,5622-5.html)

I chose this monitor as I am just more of a casual gamer rather than a hard on competitive gamer. I also kind of like seeing nicer colors on my screen though I have not done any professional work myself that's color sensitive.

There's people here saying, is G sync worth it?

Yes, but to a degree. In order for G Sync to work all the time, the FPS must be below or exactly the monitor refresh rate all the time. If the FPS goes over, the principal of screen tearing will still apply since your monitor will not be able to process the extra frames and end up tearing them.

However, with a 120Hz or higher refresh rate monitor, you won't see screen tearing as much as a 60Hz or 75Hz monitor, simply because you will be seeing more "full frames" than lower refresh rate monitors of course. T

So to keep G Sync on, can I simply just turn on V Sync and Ultra Low Latency on On or Ultra and will that induce input lag?

Here is a video I watched that convinced me to use this settings:

To me, it's a matter of psychology because numbers on the screen simply can irritate/trigger some people who are very sensitive to the numbers like FPS, ping, etc especially when they play competitive games like CS:GO and monitoring those at the same time.

First, it will depend on how much FPS your GPU can generate as well as the frametime for it to get to your monitor. For 60 FPS, it's about 16-17ms of frametime, so that's a very high input lag if you decide to turn on V Sync on any monitor, locked at 60 FPS no matter the game. Turning off V sync eases the input lag, simply because you're gonna be seeing the excess frames being processed on the screen as screen tearing or like half of it.

However, it will also depend on your monitor's pixel response and input lag. For my case, since my monitor is approx ~9ms, turning on V Sync and ULL Ultra gave me a Frametime of 8.6-9ms according to MSI Afterburner, at 116-120FPS. So, my monitor will definitely not have input lag as bad as a 60Hz monitor for sure.

I also decided to turn off V sync just to see if it reduces input lag. I also took out my iPhone, set it to slow mo mode and recorded the response. To me surprise, the input response were marginal. In fact the monitor processed that teared frame a bit faster than when my PC played the sound of the gun I fired on the speakers. But it was not drastic (to me) that warrants me to disable V Sync.

With that being said, because I don't really monitor the numbers a lot unless my system is unstable, I played CS:GO competitive matches, Overwatch and some Rainbow Six Siege games with V Sync on and off. From an average person PoV, I didn't notice any massive input lag since the frame time is matching my monitor. Also , I didn't notice any difference in my gameplay performance (I didn't get a low K/D/A because my V Sync was on).

So, Yes turning on V Sync to keep G Sync active does have input lag, but it also primarily depends on how much time it takes for your monitor to respond to generate and display the frame. If you have 120Hz and 9ms like mine, you will not get input lag as much as a 60Hz and 16ms monitor. Which is a large improvement. Or if you have a monitor that has faster pixel response time (such as TN panels) even though 120Hz, then the lesser input lag with the generated excess frames will be more worth it since you will be able to get those.

It's a matter if you want a trade off - do you want very slight input lag for no tearing, turn on V Sync and G Sync (if your monitor is 120Hz or above)? Or if you are very sensitive to even the slightest input lag or frametime, turn it off.

As for monitors that have no G sync but 120Hz or above, if your FPS does not match the refresh rate, higher or lower, you would get tearing.

TL:DR then

G Sync is only worth it if the monitor has a refresh rate of at least 120Hz, but only if your FPS is 120 or below. Higher than that renders it useless.

Don't buy any G Sync monitor that has a refresh rate of 75Hz or below if you plan to do competitive gaming at a higher refresh rate; It's a waste of money since the input lag to keep it on is not a good trade off, unless you don't mind playing your games at 60FPS or below in 2020 in like 4K resolution.

Please also remember that this post is just from my personal experience and knowledge. After all, you decide yourself on how you want your own rig and setup to perform. There are definitely drawbacks when V Sync is on and off, but it will also depend on the monitor you use, similarly to the drawbacks of using a stock CPU cooler compared to a larger aftermarket one ;)

I must be very sensitive to it because when I have V-SYNC on it's not "laggy" as such, but I can definitely notice when I have V-SYNC off , that 0.2 ms or whatever it is I can notice it. For me, it's all about the having the best experience.

Also, I disagree when you said G-SYNC is pointless at 75hz or below. I had a 4K 60hz G-SYNC monitor for years and it totally made 4K gaming SOOO much better then when I gamed at 4K without it. No tearing with G-SYNC when you're within the range, so G-SYNC is a must whether it's 60hz, 75hz 144hz or 165hz.

what I meant is the drawback in the competitive spot to keep G Sync on.

But it's ok if anyone wishes to go 4K to admire the graphics more. For me I am just in the middle.
