Witcher 3 + g-sync

I have asus rog 278q monitor and my I have 3 options ( 144hz, 120hz and 60hz) While playing witcher 3 all maxed out I have 90 fps average . Want to use g-sync . Should I lock to 90 fps or sth like that to fully use g-sync? And how should I do it ? Should I use V-sync in game?

Thank you.

  1. Do not use V-Sync. It will cause notable frame drops, possibly below 80 and maybe even 60. G-Sync is mainly useful for games that run right around the 60FPS ballpark, because it optimally shines in those tough titles, and whereas most people get them to see the extra FPS their cards squeeze from the poor little AAA's their Titan X's crush, their main use is to really get the best out of the monitor, to avoid screen tearing, and to give an overall good experience, paired with your NVidia GPU. G-Sync will work on 144Hz to show up to 144FPS. You don't have to lock any frequencies unless you plan to dual-monitor with a secondary setup that's at a lower frequency than the other. :)

  2. G-Sync is a type of V-Sync and it operates in two modes.

    G-Sync with V-sync on will cause sync to operate in the entire range up to 144hz. At 144hz it will hold the refresh rate at 144hz (typically 143-144hz it will bounce around a little)

    G-Sync with V-Sync off will still run G-Sync across the entire range, but will let the FPS exceed 144hz when possible. Basically no syncing at all past 144hz.

  3. So basically I can keep my monitor locked at 144hz . Use g-sync. And in game my 90 fps average will sync with my monitor at 90hz? Is that right. Didn`t quite get the answer.
    And you suggest me to leave v-sync off, yes?

  4. Or should I use ULMB instead?

    In that particular use case, V-sync on or off doesn't actually matter, since it can't get to 144hz.

    G-Sync controls the monitors refresh rate rather than having it set in advance, so if your system can handle 90FPS it will run the monitor at 90Hz. The key is that G-sync eliminates tearing, no runt frames will make it to the screen and it won't start drawing a new frame in the middle of the screen.

    ULMB is a good option when you can consistently stay above 144hz, this will get rid of ghosting at the expense of brightness typically, and tearing is again possible. A good idea on titles that are very dark and have a lot of fast movement.
