i have a pixio px277 prime neo with 180 hz refresh rate (the refresh rate I use when I switch off gsync for a smoother experience is 100hz because I can consistently maintain 100 fps with no framtime spikes whatsoever, and when I have gsync on I just leave the refresh rate at 180hz and then cap the fps to 100 for the same reason, the gsync range is 49hz-180hz btw so i am not in LFC), I have a rtx 5070 ti and a ryzen 5 7600x cpu with 32gb crucial ddr5 ram (bought it before the ram shortage, also expo or xmp being on or off has zero effect whatsoever), and I have gsync enabled for fullscreen and windowed applications (i tried for fullscreen only and it made zero difference) and I know that gsync is working because I enabled the nvidia indicator and it showed gsync is working, and again this wasnt the only monitor I tried, I also tried an asus TUF monitor that is gsync certified too (i forgot the specific model name if i am being honest but I know it was an asus TUF with a 144hz refresh rate) and it still had the exact same issue as the pixio monitor, and I have a high end gaming laptop (rog strix scar 18 with a 4080 laptop gpu and an intel core i9 14900hx with 32 gb ram) and gsync on the laptop shows the exact same issue. I tried display port and HDMI and neither made any difference whatsoever, oh and also my gpu is not overclocked or anything, also I should say that it actually shows micro stuttering, like i can see very short stutters that happen a lot even though the frametime graph is completely stable, all of my drivers are up to date, and yes I tried DDU multiple times, no difference sadly

That model is not on the G-SYNC Compatible FreeSync list (https://www.nvidia.com/en-us/geforce/pr ... ors/specs/), so it's probably not certified.

There's no in-depth reviews of it either, so I can't confirm on its LFC threshold or VRR range either.

No system can consistently maintain x FPS with zero frametime spikes 100% of time in 100% of games, regardless of its capabilities. System-side readouts can't pick up all frametime issues, for instance.

Whether it makes a difference for your issue, it's not strictly recommended. See:

Without the model, I can't speak specifically on that one either, but seeing as you're claiming both had the "issue," you're probably expecting something from VRR that it cannot do.

Laptop G-SYNC is not equivalent to desktop G-SYNC with a dedicated GPU and monitor, at least in most cases, so that doesn't say much.

G-SYNC will show all system-side stutter. It won't reduce or prevent it at all. It only prevents stutter from traditional V-SYNC whenever the framerate is within the refresh rate, but its primary goal is to prevent tearing; any increased smoothness is just a side-effect.

I.E. you should see the same/similar amount of stutter with G-SYNC on + V-SYNC on + framerate within the refresh rate as you would with G-SYNC off + V-SYNC off + framerate within the refresh rate.

Standalone V-SYNC + framerate sustained above the refresh rate can and often will appear smoother than G-SYNC on + V-SYNC on + framerate within the refresh rate, because, in layman's terms, standard V-SYNC can mask frametime performance issues via added latency from delayed frame delivery (unlike VRR, it throttles the framerate, forcing the GPU output to sync to the display), whereas G-SYNC reflects system frametime performance near 1:1, jitter and all, just without tearing.

If you're using G-SYNC on + NVCP V-SYNC on + in-game V-SYNC off + FG off (to rule it out) + an ~172 FPS limit (try RTSS async for the most stable frametime, to start) at a 180Hz physical refresh rate and your monitor model has full LFC support, that's the most optimal VRR configuration you're going to get.

Any remaining stutter you see, G-SYNC can't and won't fix.

I checked the ASUS monitor model, its an ASUS TUF vg27aq 144hz, there thats a gsync compatible monitor and its showing the exact same issue as the pixio monitor, and if apparently I am having stutters that are somehow undetectable by a frametime graph then how do i even begin to solve this issue? and I never once said gsync fixes stutters, and also I am using RTSS async

Then there's probably nothing wrong with G-SYNC in this case. Instead, it may be revealing stutter standalone V-SYNC isn't. Again, no-sync will likely show similar.

I experience stutter all the time. Stutter, to some degree, is unavoidable.

In your case, it just depends on if it's that, or if it's some form of avoidable stutter, such as from a background process, like an RGB program, or the like, but since it's occurring across multiple configurations for you, the latter is unlikely.

Your topic (which was created in the G-SYNC sub-forum) is literally titled "gsync is completely fucked." And both it and your original post clearly suggests you're pointing to it as the primary cause, and I'm telling you it can't directly cause or fix this, at least how you've been describing it.

I've given you a brief overview on how VRR works and what to expect/not to expect in this respect, and that's about all I can offer here.

Beyond that, In my experience, these type of stutter topics never really end, either because the root cause of what the OP is trying to convey is never quite discovered, resolved and/or explained to their particular satisfaction, or, the OP isn't willing to accept the stutter they're experiencing is considered within expected levels in the given scenario.

Sadly, it's only "outdated" and/or "inadvisable" now because consistent frametime performance, on average, tends to be less achievable on modern systems, games, and higher refresh rates than when the G-SYNC 101 article was written, which is why I have it as a minimum starting point in the recommendations.
I was talking about frame gen though. Obviously FG didn't exist back then to begin with. Without FG, the "-3 or reflex cap" advice is still perfectly valid.

Sure, gotcha.

Either way, "-3 FPS" without exception isn't and never technically was intended to be taken literally in my recommendations, yet that seems to be the takeaway from the average reader more often than not.

I will ultimately caveat that in the optimal settings recommendations with a note + link pointing to a new Closing FAQ entry when I get around to it (TBD).

I FIXED IT, I FINALLY FIXED IT, after so much experimenting, apparently it turns out this whole time the issue was ray tracing, I am not kidding, the moment I turned it off my game immediately became smooth as butter, this really confuses me though because my 5070TI should be more than capable of comfortably running ray tracing just fine, but no any ray tracing setting being on immediately makes the game run like shit SPECIFICALLY WHEN GSYNC IS ON, again when its only vsync its perfectly smooth

Ray tracing also places a high demand on the CPU, mainly because of BVH construction. I believe large cache sizes help (meaning X3D CPUs perform better due to their 3D V-cache.)

Consoles can build the BVH for ray tracing on special hardware on the console, but PCs don't have that and it's done on the CPU.
