Question Vsync on or off with freesync on? what about FRTC?

[Katusch]

Hi,

I bought a new 144 HZ gaming monitor (Dell S2719DGF) to play First person shooters and now i dont know if i should turn vsync on or off when freesync is activated, and if i should use FRTC, which is AMDs frame rate limiter, and if i should also use ingame frame limiter.
I have FRTC on and set at 141 FPS in the radeon settings atm, but i dont know if that make sense tho.

I got also a new Radeon Vega 56, but the rest of the hardware is a bit older so i won't reach 144 HZ in new games most of the time anyway:
Cpu INTEL Core i5 4570 PC1150 6MB Cache 3,2GHz
ASRock H87 Pro4 1150 ATX
Ram DIMM DDR3 Crucial 16GB / 1600Mhz Ballistix Sport

I play in full hd resolution.

Anyone knows what the best settings are for me?

Vsync is used so if you do go over Freesync range fps is kept within. Vsync will cap fps right on the threshold if you're able to get more than 144fps which might have input lag. If not then all good to use vsync. If there's input lag, cap fps 1 or 2 fps lower. Vsync usually has no affect within Freesync range.
