Fighting games settings recommendation

[Bubu]

Hello, i want to know what kind of settings do you recommend for fighting games, usually fighting games are locked at 60 fps
From what i ve know, high refresh rate do lower input lag/latency

Nvidia Low Latency

Does it work for such games at 60 fps?

G-Sync vs V-Sync OFF

I usually enable G-Sync since its basically same input lag as V-Sync OFF + it gets rid of tearing/stutters
But why in tournament they dont use G-Sync (i assume its not set on G-Sync)

Power supply management mode

Balanced or at maximum performance?

Thanks
