Blur Buster's G-SYNC 101 Series Discussion

Talk about NVIDIA G-SYNC, a variable refresh rate (VRR) technology. G-SYNC eliminates stutters, tearing, and reduces input lag. List of G-SYNC Monitors.

I think Reflex is fighting against itself or something. My monitor has an OC mode to 180 Hz so if I use that reflex seems to cap fps at 171.

If I then set a frame limit below 171 then the game behaves fine. As soon as I set 172 the issues start to happen.
With G-SYNC, Reflex (and LLM Ultra) auto limits itself lower the higher the refresh rate is, so that's expected. At 240Hz, it limits to 224 FPS. It's just how it is. Ask Nvidia *shrugs.*

And to be clear here, Reflex has both an auto FPS limit for keeping the framerate within the G-SYNC range (the 171 you're seeing at 180Hz), and a dynamic FPS limit for whenever the GPU usage becomes maxed (at which point it caps slightly below the currently achievable average).

Again though, prioritizing render queue settings intended to reduce latency in GPU-bound scenarios for non-GPU-bound scenarios is a bit of a moot point. If you don't like what Reflex is doing (benign as what you're seeing is), and your system is not GPU-bound in the given game, you don't have to use it.

It continually perplexes me as to why such settings seem to be fixated on by so many.

Setting a manual FPS limit to keep G-SYNC in range AND your GPU usage from maxing is as good as you're going to get on the render queue and display latency front where a no-tear configuration is concerned.

Settings like LLM and Reflex are really only applicable (and intended) for situations where your system can't maintain a constant framerate and it begins to frequently fluctuate below your desired target.

It's the marketing. Like unless I'm a mega engaged gamer when I go to the Nvidia reflex main site and see "Enable Reflex Low Latency mode in top competitive games such as Apex Legends, Overwatch, and Rainbow Six Siege to boost responsiveness."

It 100% sounds that a gamer should enable this at once. In no way does the main page communciate stuff like "Only when you are GPU bound" so ofcourse people are going to wonder about the setting.

Nvidia's marketing is correct, so long as the competitive games in question are being run on a mid-end to lower-end system at maxed out settings in GPU-bound scenarios, but as we both know, most serious comp gamers prioritize latency and higher framerates over visual quality and often play at compromised (or the lowest) settings with lower and/or custom resolutions, and typically on higher-than-mid-end systems, where GPU-limitation won't be as prevalent.

The irony is, settings like Reflex are much more suited to single-player only eye-candy games, yet are predominately featured in online comp games instead.

Anyway, it's not the first time Nvidia PR has shouldered people like me with the headache of explaining the nuances and contextual usage of their settings off-record.

Apologies if this has been asked many a time before (my rudimentary searches found little), but how do games that are locked to a 60 Hz refresh rate such as Sekiro: Shadows Die Twice (and, most likely, the upcoming Elden Ring) relate to the 'G-SYNC ceiling' as mentioned in G-SYNC 101? Is the G-SYNC ceiling the specified refresh rate of the display, i.e. 120 Hz, or is it the 60 Hz refresh of the game?

Considering G-SYNC locks the refresh rate to an integer multiple of the frame rate, which will be reflected in a live refresh rate measurement in the display either way, how does one then discern if there is a refresh rate lock in place (as with Sekiro) in order to set an ideal frame rate limit (presumably 57 FPS if the ceiling is 60 Hz, or the in game 60 FPS limit if the ceiling is the maximum specified refresh rate of the display)?

EDIT: Sorry, brain fart in the second paragraph, my LG CX reports the live G-SYNC refresh rate as well as the refresh rate of the signal itself (i.e. 3840 × 2160P@60). I suppose my question still applies regarding what the G-SYNC ceiling might be in this case, assuming a 120+ Hz signal can't be forced through windowed modes or what have you.

The G-SYNC ceiling is relative to the current physical refresh rate of the display. If it's 60Hz, then the ceiling is 60Hz, and so on. I.E. if your desktop is set to 120Hz, but the game is running at 60Hz, the game takes precedence.

Most monitors show the current maximum physical refresh rate somewhere in their OSD. You should be able to check that while in-game.

As for Souls games, disabling fullscreen optimizations in the .exe file should allow the game to run at the max physical refresh rate of your display. It's what I do when I'm playing them as well. Odd quirk.

I answered in the post above this one.

Hey i found very good article about ultra low latency but games that are locked 60 fps (mostly fighting games)
its wrote in Japanese but with google translation, i can read 8-)

https://ascii.jp/elem/000/001/964/1964205/

They claim after tested and compared, NULL is not effective on such games (with insignificant difference), so my question its why in others kind of games such as fps, NULL might be effective? (probably because those game are locked at 60 fps i assume)

Anyway its great source, i wanted to share it here

Settings like NULL and Reflex only affect the render queue (which isn't directly G-SYNC related), and only reduce latency in the render queue when the GPU usage is maxed. When the GPU usage isn't maxed, those settings have little to no effect on latency. That's probably what those tests where showing.

The only G-SYNC-related components of LLM and Reflex is the auto FPS limiter, and that's to the ensure the framerate remains within the refresh rate to keep G-SYNC in range. Any other effects from those settings only have an indirect impact on G-SYNC performance, and would occur with or without G-SYNC enabled.

Hey, i have a question for G-Sync

In Blurbuster guide
-> Set up G-SYNC > Enable G-SYNC, G-SYNC Compatible > Enable for full screen mode.
-> Manage 3D settings > Vertical sync > On (Why?).
On NVCP, i have monitor technology or something like that, when i selected G-Sync, it automatically enabled Vertical Sync: 3D application parameter

I also use frameratelimiter on NVCP (162 fps instead of 165 fps because of my 165 hz as refresh rate)

Does it change anything in comparison of the Blurbusters recommendation?

Thanks

G-SYNC + NVCP V-SYNC + a minimum 162 FPS limit at 165Hz is the recommended configuration for the lowest latency, tear-free G-SYNC operation, so you should be good with your stated settings.
