G sync with V sync??

I just got a new G sync monitor and noticed it wasn't working. Framerates going above the 100hz refresh rate. My monitor is the Acer Predator X34. I read a few comments and articles saying G sync and V sync both ned to be enabled but the discussion is back and forth. Which one is true??

Afaik to use G-Sync you cant enable V-Sync at the same time and V-Sync overall causes input lag while G-Sync doesnt

Gsync operates in a range, much like vsync, but doesn't lock to a certain framerate. It's variable refresh rate technology. You pick either Vsync or Gsync (or freesync obv.) but not both.

You can use both G-Sync + V-Sync or G-Sync + Fast-Sync at the same time but that defeats the whole purpose of G-Sync whenever you hit the FPS that matches or exceeds your max monitor refresh rate since you will be introducing a huge input lag.

You're better off using a FPS cap (preferably the one built into the game) to limit your FPS by about 2-3FPS bellow your monitors max Hz (to avoid the range of error in SW).

Dont usr NVIDIA Inspector to limit FPS, it introduces almost the same amount of input lag as V-Sync for some reason. (Use Riva Tuner).

Like @WereCat said, the proper setup for G-Sync is to enable it and then enable global Vertical Sync in NVIDIA Control Panel. Then put limiter on your max fps to just below your refresh rate. Best way is to use ingame built-in (if there is such an option) and if not then Riva Tuner. 

 

Note that the Vertical Sync in NVIDIA Control Panel is the one you turn on but in game option you turn VSync off.

 

This site goes in depth about the topic of setting up your G-Sync properly:

I do the same for my 4k freesync, i lock frames at 58  and vsync off, smooth like a baby's butt

Let's agree to disagree
