Stuttering when G-Sync is turned On

[No_More_Oxygen_]

Hi, I recently found the source of most of my stutters on my system when gaming, I'll use Ninja Gaiden 2 Black and Assassin's Creed Shadows as an example:

In both of these games if G-Sync is turned on the stutters are very noticeable and very frequent (one every few seconds), not while standing still but when traversing the world, moving the camera or doing anything, really.
This happens with G-Sync + V-Sync On in the NVCP and Off/On in-game, G-Sync On + V-Sync Off in the NVCP and Off/On in-game. These stutters completely disappear as soon as I turn Off G-Sync on my monitor and regardless of the V-Sync option in-game or in the NVCP.

It has to be noted that this does not happen for every game. Unleashed Recompiled, Street Fighter 6, Tekken 8, Resident Evil 5/6 and so on with G-Sync On do not have these stutters.

The easiest solution would be to move on and play without G-Sync, problem is that if I don't have G-Sync On and play with Frame Generation I get Screen tearing, Unfortunately.
Do you guys experience stuttering when playing with G-Sync?

These are my Specs:

LG UltraGear 27GS75Q
ASUS TUF Gaming B460 Plus
GIGABYTE GeForce RTX 4070 WINDFORCE OC V2 12GB
Intel Core i5 10400F 6 Core 12 Thread 2.90GHz
Crucial P2 NVMe 1TB + Samsung 870 QVO SSD 2TB
Corsair Vengeance LPX DDR4 32GB 3600Mhz
Cooler Master MWE 600 WHITE 230V V2

Thanks.

The best solution for me is to focus on 1/2 Vsync with Nvidia Inspector.
This eliminates stuttering completely (90 fps on a 180 Hz monitor because of 1/2 Vsync).
If I try to cap the fps otherwise, it stutters no matter what I do.

I also use Special K so that menus, maps, and cutscenes also run at 90 fps.

Gsync is disabled. i play with xbox one windows controller.

Asus TUF Gaming VG3A 180 Hz
i7-13700KF
Palit RTX 4080 with 572.70 driver
Samsung 980 Pro NVMe 2 TB
32 GB DDR5 6000 MHz

I'm doing the same, running AC Shadows with half vsync 1/2 the refresh rate, I don't have any stuttering, the problem is that when I turn the camera it oscillates, shakes, I've done everything, I disabled Gsync, locked the fps in other programs, I tested on Windows 11 and 10, I switched to old drivers and nothing worked, my monitor is 144hz, R7 5700x CPU and an RX 4070, only activating Vsync to 1/2 the refresh rate through the driver or NVE solved it, unfortunately it causes a small input lag on the control

I have this problem with many games where using any framerate caps with g-sync causes stuttering and I have to resort to capping the framerate with 1/2 vsync.
I'm not exactly sure why some games are fine while others are not, but it is what it is, I'll take the smoothness of vsync with higher input lag.

In several games I just leave the monitor at 144hz and lock it at 90 or 60 fps and when I turn the camera it is smooth, without shaking or input lag, but in this AC Shadows the camera shakes when it turns around the character, I think vsync 1/2 is very good for half the refresh rate, the only bad thing is this small input lag

No, the only bad thing is 1/2 refresh VSYNC turns G-Sync off.

Just use a good framerate limiter. I happen to be the author of a very good one I can highly recommend :) Gets rid of the 30 fps limit in cutscenes also.

I get that you're proud of your tool and good for you, but after trying it, I'm afraid I have to say it's just another frame limiter with the same problems as other frame rate caps when using g-sync. It doesn't fix the stuttering or jerkiness when panning the camera in a bunch of games and capped 1/2 vsync is infinitely smoother and feels much better to play regardless of higher input lag, at least if someone can maintain the target framerate.

I feel exactly the same.

There are games where Special K works wonderfully (Elden Ring, etc.), but with other games, nothing seems to work better than 1/2 VSync.
Guild Wars 2, for example, stutters so badly in certain regions with GSync enabled that it is unplayable, with 1/2 VSync in the same areas, it doesn't stutter at all, or only very slightly.

That's stupid, because I actually switched to a GSync monitor for Guild Wars 2,
because on my 60Hz monitor, Guild Wars 2 had severe input lag with VSync on,
and with VSync off, it didn't stutter at all but did have severe tearing.

So I thought a monitor that eliminated input lag and tearing would be the solution...
but GSync and GW2 don't mix on my system.
However, with 1/2 vsync and 90fps (at 180hz) I still don't have any tearing and the input lag is also much less than with the other monitor and doesn't bother me at all.

Not proud of my tool.

I'm trying to explain to you as someone who works on this stuff constantly, why you don't use 1/2 refresh VSYNC. It's not solving your actual problem, it's putting a band-aid on it and then causing extreme latency.

You likely aren't even getting G-Sync in the first place, and setting 1/2 refresh VSYNC is just compensating for that fact alone. You won't do this because you seem to think I'm 'proud of my tool', but Special K can tell you whether G-Sync is even working or not. It's more complicated than just opening your monitor's OSD and looking to see if the number is changing dynamically.

For a lot of people, they can't get G-Sync in this game working at all. The only solution is to disable the NVIDIA overlay.

SK will tell you immediately if that's your problem, in the control panel. It will say "Supported + Inactive" instead of reading the active VRR rate.

That is the reason I told you to use SK, it will help you pinpoint the actual problem so you can eliminate it. Keep disabling crap until VRR is actually working, then never run the thing you identify as causing the problem again.

This makes no sense as disabling the framerate cap gets rid of the stutters. Doesn't matter if it's in-game, nvcp, rtss, or specialk, they introduce stutter in certain games and disabling them works.

G-sync is working just fine for me even in this game until I cap the framerate while using g-sync, and because I don't want my gpu to max out all the time trying to run 180fps, one of the best options is (unfortunately) 1/2 vsync as that doesn't have the same issue.

Changing the monitor's refresh rate to something like 90hz and running that with Vsync while keeping G-sync also works.

Yes the input lag sucks, but it is what it is.

i do experience stuttering with framegen, but without it i only get about 50 - 60 fps because of optimization

In my case framegen does not introduce stuttering when G-sync is off but I do get screen tearing. do you have G-sync/Free-Sync on?

Did you solve the issue finally?

I did, after a clean install of windows 11 pro and thanks to the release of the 1.0.2 update almost all of my stutters are gone. If I see any stutter now it doesn't really affect me as much as before since they're so rare now
