G-sync / v-sync and reflex low latency?

Does it make sense to use these settings?

G-sync On

V-sync On

Fps limiter to a value that my pc can always keep stable.

Nvidia low latency in the control panel on Ultra.

now my questions.

where is the difference between the low latency in the nvidia control panel and the nvidia reflex setting in games like fortnite or warzone and does it make sense to have both activated at the same time?

The YouTube channel battle (non) sense also said that you should switch off the low latency option if you set your fps to a value that your pc can always hold, why is that?

no

G-Sync -> Yes, definitely

V-Sync -> it depends

FPS-Limiter -> If you don't use V-Sync then it usually makes sense not to exceed the refresh rate of the monitor, which can lead to tearing.

I have always understood that v-sync prevents tearing but does not add any input lag if you stay below the highest frame rate of the monitor. In my case below 144hz.

no

V-Sync does cause input lag and limits you to 144 fps. You can't change that either.

You can set an fps limiter to 143, for example, so you have much less input lag and no tearing.
