Weirdest G-sync Compatible Problem, help needed!

[rcmo]

Hello,

I got some strange problems with G-sync compatible displays on two different systems.

System 1 PC :
RTX 3080 ti
i9 9900k
32 GB of Ram
NVME drive 2TB
Gsync compatible Monitor
Windows 11

System 2 Laptop
RTX 4060
AMD Ryzen 5 7535HS
16GB Ram
NMVE drive 500GB
Gsync compatible Display
Windows 11

So, I usually cap my framerate using either RivaTurner or Nvidia CP to 40fps when playing singleplayer games. I just dont mind 40fps cap to get stable 4k framerates. However many games work flawlessly and smoothly without any stuttering, but some games I get terrible stuttering even though my fps is rock solid 40. As mentioned above im playing on Gsync compatible display on both system. However, I do have a gsync monitor as well on my PC. And there is a zero issue there, which led me to believe it's the Gsync / vrr problem.

Couple things i noticed while trying to pinpoint the issue :

-First one being as i mentioned above is that this is NOT happening on my G-sync native display, but is happening on G-sync compatible displays.

-Also this is only happening when frame rate is near 40fps cap (but still above). That's why is stuttering happening when i'm in more demanding areas. When in less demanding areas stuttering disappears (possibly because fps goes above lets say 47-50 fps). Keep in mind that my fps is capped at 40 and never goes below. So my first thought was that VRR range is from 50 fps. So I try to cap on 50 fps or even 52, then reduce graphics settings to maintain stable fps over 52. However there comes stuttering in demanding areas again even though fps is stable 52, in less demanding areas stuttering is basically non existent. Also worth noting is that GPU usage is high when stuttering occurs above 88% usually (i guess that's because more demanding areas).

- Also to mention, super weird but gameplay feels very smooth when fps goes under 40fps cap, lets say 37. It feels as smooth as uncapped. So stutters only when fps is 40.

- That being said, funny thing is thou that gameplay is smooth as butter when I uncap fps no matter if i'm in demanding areas or not (apart from usual fps fluctuation depending on area i'm in). Yeah i guess possible solution would be uncapping the frame. But that's not ideal either as I'm used to locked fps.

Some games that stuttering above is happening:
- Horizon Forbidden West
- AC Mirage
- Alan Wake 2
- Resident Evil 4 Remake
- Avatar Frontiers of Pandora
- Far Cry 6
- Starfield
- Fallout 4

Some games that are buttery smooth 100% of the time:
- Last of Us part 1
- Lies of P
- Elden Ring
- Cyberpunk 2077
- Dishonored 2
- Dying Light 2

I did sooo many things to resolve the issue without any luck. Ive tried all usual settings in Nvidia Control Panel, some windows settings and so on. Tried many combos from Nvidia Control Panel without avail. I did not try to change things in Bios that much as i'm not really aware what different settings does.

So if you have some advice I have not tried, I would gladly hear it.

Also no disrespect but im here for a possible solution, and not to be lectured how i should not cap fps and so on :)

All this stuff in both systems are on one ssd. That's part of the problem right there.

The other issue is WinOS.

You need to really sir down and seriously tweak the F out of WinOS for anything to work at all, like Ganes.

Nvidia needs to be set to prefer max performance.

Page File needs to be manually configured properly.

Disable Fast Startup + Hibernation.

Disable Xbox Gamebar and Windowa Game Mode.

Disable Driver updates for Windows Updates.

Download and install all latest drivers. Such as using the Intel Driver Assist website. For AMD that means getting the Ryzen Chipset Drivers and NVIDIA GPU drivers and disable onboard GPU by forcing apps to only use the dedicated

Hi, what do you mean? On my Laptop i have a single Nvme SSD. But on my PC i have couple and i use one strictly for games only.

I will try your suggestions above

If the only factor making the difference is gsync vs gsync compatible, then I think you already have your answer.

Gsync is a hardware solution, using a gsync module in the monitor. Gsync compatible isn't even gsync at all, but rather using the Freesync standard. They have the same goal, to regulate frame rate and refresh rates, however they don't do the same thing to achieve it.

Seems like you've found a scenario where Gsync works better than Freesync.

And Games such as Fallout 4 for example it is basically a must to use 3rd party Launcher that allows you to better configure the game graphics settings. As the bundled Launcher is terrible at best and that game definitely needs a 60 FPS lock enforced on it.

why cap the fps at 40 when using gsync? it might be 40 or 43 - 144hz gsync range, there is a lower and upper (max refresh rate) limit for gsync. You want to cap the fps at 1 below the max (ie 143 if 144hz display)
None of your systems are slow just let the fps do its thing, Vsync off, gysnc on and it's butter..

I have a LG 27GL850 144hz and Phillips 48OLED806 120hz and have no issues with gysnc, just don't cap your fps so low that it may not work, ie stutter because of capped fps and low gpu usage because of it and possible screen tear as maybe below the gysnc range.

Its actually high gpu usage when stuttering occurs.
