Doubts/questions about NVIDIA control panel settings

[hitmanboy47]

Hello to the entire blurbusters community.

I have a 144hz compatible gsync monitor with internal adaptive sync selected to off and with internal response time selected to fast.

Windows 10 configuration:

Hardware-accelerated GPU scheduling: OFF
Variable refresh rate: ON


Speaking only of Singleplayer video games I have some doubts/questions, all issues regarding underperforming hardware are excluded:

1) If I understand correctly the GSync ON + VSync ON option is the safest and can be considered global but not totally free of possible tearing effects. Also with this combination there are no fluidity problems if I can't reach 144 FPS. Right?

2) Adding a frame limit to the previous configuration that is 3 lower than the monitor's refresh rate guarantees an elimination of tearing but the limit value must also take into consideration how many fps the pc can actually generate for the video game. Right?

3) The low latency mode is interesting even if it is limited to games that do not use Vulkan and Directx 12, but since it is not guaranteed to work properly globally it is better not to activate it from the Nvidia control panel. Right?

4) We know that there are old games that due to engine or programming limitations cannot go beyond certain fps. How should I deal with the NVIDIA control panel settings? Will I use the G-SYNC ON + VSYNC ON + 30 FPS Limit option?

I apologize in advance if these questions have been asked before.

Greetings,

Shouldn't this be set to ON if you want g-sync to work?

1) If I understand correctly the GSync ON + VSync ON option is the safest and can be considered global but not totally free of possible tearing effects.

Gsync ON + vsync ON is totally free of any tearing. Gsync ON + vsync OFF might have tearing sometimes.

Also with this combination there are no fluidity problems if I can't reach 144 FPS. Right?

Right. Unless the monitor itself doesn't do VRR very well, or the GPU driver's support for this monitor isn't very good.

2) Adding a frame limit to the previous configuration that is 3 lower than the monitor's refresh rate guarantees an elimination of tearing

That's already guaranteed in the gsync ON + vsync ON case.

but the limit value must also take into consideration how many fps the pc can actually generate for the video game. Right?

No. That's only needed if you want more frame rate consistency when playing the game. For example if you don't like it when a game runs at 90FPS in some areas and with 140FPS in others, you might apply a 100FPS to limit the variability to 10FPS instead of 50FPS.

3) The low latency mode is interesting even if it is limited to games that do not use Vulkan and Directx 12, but since it is not guaranteed to work properly globally it is better not to activate it from the Nvidia control panel. Right?

It either works or doesn't. So it's fine to just enable it. For games where it doesn't work, it won't hurt either.

4) We know that there are old games that due to engine or programming limitations cannot go beyond certain fps. How should I deal with the NVIDIA control panel settings? Will I use the G-SYNC ON + VSYNC ON + 30 FPS Limit option?

If the game itself is capping its frame rate, then there's no reason to apply an nvcp cap. Unless the game's cap is too unstable and has too much variability (resulting in jittery motion). In that case, you can try and make it smoother with an nvcp FPS cap.

I didn't think I was so ignorant, all these years I thought I had gsync on just because I saw that from the NVIDIA control panel the checkmark on gsync was turned on.

I had no idea that I had to enable it from the monitor as well.

What to say? You never stop learning.

I thank you for your patience and detailed answers RealNC.

Greetings.

So the thing about us having to have 3 FPS under the HZ is "a minimum" right? If I have GSYNC + VSYNC on and 165 HZ Monitor I can also cap the FPS at 100 and still benefit from everything being on?

Yeah. A 162FPS cap is the highest cap you can use and still avoid v-sync latency. Capping lower than that is no problem.
