Blur Buster's G-SYNC 101 Series Discussion

[jorimt]

Is limiting your frame 3 frame below your monitor refresh rate really doing everything if for example you are using a "170hz" (an XG27AQ 144hz/170hz with overclocking) monitor that VRR ranges goes from 48Hz~170Hz for DisplayPort, but only use the out of the box 144hz native frequency?

The minimum -3 FPS limit is relative to the currently set max refresh rate.

I.E. if your 170Hz-capable monitor is set to a physical refresh rate of 144Hz, the recommended FPS limit is 141 FPS or under, whereas if that same monitor is set to a physical 170Hz, the recommended FPS limit is 167 FPS or under, and so on.

In this setup, is 144hz considered display’s maximum refresh rate and therefore a 141fps limit through NVCP is requiered for that smooth g-sync experience, or 170hz is still considered the maximum refresh rate, and a 144fps limit through NVCP(or in-game settings as it's often an option there) is the way to go?

Always -3 fps.

Hey I was wondering what settings I should use if I absolutely hate stuttering, I don’t rlly mind screen tearing that much but I absolutely hate stuttering. I have a g sync compatible monitor with a 3070rtx, and I don’t know if I should use g sync on with v sync off or with v sync on, let me know what setting is the best for if I HATE stuttering.

You need a bigger safety margin when you're at higher refresh rates.
So I prefer to always say between 3-5% below.

It works best with two separate VSYNC settings (ON in drivers, OFF in game).
Maximum fluidity usually occurs with:

G-SYNC ON in monitor menus
G-SYNC ON in NVIDIA Control Panel
VSYNC ON in NVIDIA Control Panel
VSYNC OFF in-game menus
Cap about 3-5% below maximum Hz using the in-game framerate cap.
You can also try an RTSS cap instead of in-game.

In addition to what the Chief said, there will be system-side stutter either way, so for that, pick your poison:

- G-SYNC on + V-SYNC on = potentially (but not always) longer system-side stutter without tearing per instance
- G-SYNC on + V-SYNC off = potentially (but not always) shorter system-side stutter with tearing per instance

G-SYNC only fixes sync stutter and can not address system-related stutter due to asset loading/streaming, shader compilation, general I/O operation, etc.

In games wherein Nvidia Reflex is present, should i still use -3 fps in-game cap?

Because I observed even though I don't use in-game caps, the fps automatically caps when Nividia Reflex on or on+boost is enabled.

I also assume if Nvidia Reflex is avail, its a must use. Right?

Thanks~

Spec: vp249qgr / r5 3600 stock /b450m / rtx2070 / 2x8gb3200mhz
Settings: nvidia g-sync = on / nvidia v-sync = on / in-game vsync = off / monitor freesync = on (g-sync surprisingly works though, i hope so because g-sync indicator shows when its on)

A manual FPS limit is not required when using G-SYNC + V-SYNC + Reflex, since as you observed, Reflex will set an automatic limit of its own slightly below the max refresh rate for the same purpose.

I also assume if Nvidia Reflex is avail, its a must use. Right?

Only if your system can't sustain the framerate at the FPS limit the majority of the time. Reflex only further reduces latency (separate of the latency G-SYNC reduces) whenever the GPU usage is maxed.

Hi, so 1st of all im very new to this forum and i literally cant find where to make a post. Anyways ill ask my question here fuk it. So...im using gsync + vsync in nvcp. My question is...should i also enable triple buffering in nvcp or no and does it matter if i have variable refresh rate in windows settings set to on or off. I switched it to on just to try it and it out feels better but maybe thats just me trippin. So ye...thats all i wanna know basically, thanks in advance

No; G-SYNC natively functions on a double buffer.

and does it matter if i have variable refresh rate in windows settings set to on or off. I switched it to on just to try it and it out feels better but maybe thats just me trippin.
