g-sync Should I turn on G-Sync when playing FPS games?

[lin9406]

Hello,

I got a 2550x1440 144hz g-sync monitor. I mainly play FPS, MOBA, and RPG games. I know turning on G-sync in RPG games is beneficial. When it comes to FPS and MOBA (Competitive games) I am confused. I am using GTX 1080 SLI. So when I play competitive games, my FPS usually exceed my refresh rate.

1. Is enabling gsync in competitive games gonna introduce input lag? Should I turn on vsync in the Nvidia control panel as well? Which option has the lowest input lag?

    I saw Linus made a video to test, at higher FPS, g-sync should be turn on with vsync to reduce input lag. But when I asked Nvidia they said I should never turn on vsync

2. Since my FPS exceed my refresh rate, if I cap my FPS, would I increase Input lag? I saw a video that said more fps can reduce input lag. But i am not sure if it is true. If it is not, then uncapped fps just gonna turn into heat.

Generally you should have G-sync and v-sync on. G-sync will take care of 20 ish to 144 and v-sync will limit the FPS output of the GPU to the refresh of the screen

not for FPS though. especially competitive FPS games

No, one or the other. 

 

Gsync is meant to be enabled with a FPS lower than your monitor refresh rate, Vsync is meant to be enabled with a FPS higher than your refresh rate

Yes more fps can reduce input lag. I would not have g sync or v sync on for any FPS game that you hope to play more competitively at

So when I play non competitive games and want to use gsync, should I enable vsync or just cap my fps?

if you have a 60hz monitor, cap your FPS at 55-58fps or so when using gysnc, when using vsync, you should have atleast 65-70fps. 

 

Use Gsync tho.

GSYNC = If you can't reach consistently the fps that your monitor's refresh rate requires. (=makes the game to not stutter)

VSYNC = If you easily get the fps and you play it casually. (=solves tearing, puts less load on your gpu = longer lifespan, less noise, consumes less power = you're saving the environment, yay!)

Neither = When you play competitively and need to reduce the input lag to absolute minimum. In such case, you go down with the settings, cap the fps at like 300 fps and try to keep it up there consistently. It's quite important for games like csgo if you play competitively and you're cereal with it. I'm not sure how much it's important for the MOBA games though.

Thanks for replying. So when I play competitively. I should turn off all the sync features. How about when I play RPG game like dark souls 3, should I enable vsync with gsync? or just gsync?

Isn't dark souls a casual game? So no need for the absolutely minimal input lag. It's important for csgo because when you play competitive at higher ranks, everyone takes it too competitively. So the proper settings matter a lot there. But it starts to not matter even with fps multiplayer games like cod and bf if you're actually not going on tournaments for the competitive plays. Nobody takes these games seriously on random online plays and such games aren't even optimized for the very low input lag to begin with. So don't worry about this approach that much

 

Also one thing to keep in mind, the input lag for gsync is quite lower than for vsync. But it's still there. Regarding your initial question, you may find this reddit post, or the article they're referring to, helpful.

 

Edit: And to the question more directly, I seem that I missed it before. You should be fine running it with gsync only, there's should be no tearing if you stay below your refresh rate. If you notice any issues in this regard, you can always turn the vsync on.

This is pretty interesting. Please correct me if my understanding is wrong. So it's alright to use g-sync while playing as long as the frames do not hit the max fps cap?

Yes, unless you need extremely low input lag (the input lag is very negligible for gsync though, unlike vsync) and you shouldn't worry about the max fps either. With gsync on, the frames caps at your refresh way anyway so there's no issue there either. Or that's at least how it works in my case. Theoretically, there's no need even for the vsync to turn on additionally either unless you notice some issues.

Well in my case i the frame outputs when i turn on the fps counter on my monitor or using fraps the fps was above the max refresh on my monitor when i don't set a max frame in cs go and in other games too.
