G-sync + 980Ti need a little help...

enigma27 · 29 Mar 2016 at 13:18

Hi Guys..

Just bought myself a G-sync monitor after using one over the weekend and being blown away..

Got a quick question.. What happens if the FPS goes over the refresh of the monitor? for instance the monitor i am getting is based at 144Hz and i know most modern games will not hit this high but what happens with older games (CS:GO) where i can easily hit over 200fps.. does G-sync simply turn off and you would get tearing again?

I know you should keep v-sync off in game but something like CS:GO has a console command to limit max FPS so is it a good idea to limit it to the max refresh so g-sync stays on?

When you enable G-Sync the V-Sync option in the nVidia control panel changes in how it works. When G-Sync is enabled the V-Sync option when on will limit framerate to the monitor max refresh, when it is set to off framerate will be uncapped with G-Sync applied upto the monitor max refresh and then disengaged above that - so at 145+fps you'd get tearing again but the lowest input latency.

Another option is to use G-Sync with V-Sync (in the nVidia control panel) on and limit the framerate ingame to around 120-135fps this still seems to give the lowest latency outside of uncapped framerate.

Perfect thanks..

So if I set them both to on it will still limit to the max refresh.

Yup.

I'm not sure off hand what the effect of changing V-Sync in the game (versus the nVidia control panel) is when G-Sync is on - it used to be ignored but with new drivers the behaviour has changed a bit.

For games like csgo it's best to leave it disabled. Let your frame rate run wild.
Csgo input latency and hit reg is all sent to the server in packets and is linked to your frame rate. Locking frame rate down will only give you a disadvantage.

For everything else though enjoy Gsync

My friend said this..

He said for games like this using the ULMB was a better option?

Depends on the user tbh, while its great removing blur I personally dont like how dark the image is becuase how this works.

Thanks.

Will give it a go tomorrow once it arrives.

Agreed with shankly - I didn't like how ULMB resulted in loss of saturation, etc. aside from CS where I'm undecided on which works best though generally you just want the faster response I've usually found the best results in competitive games comes from using G-Sync with a framerate cap just under the max refresh - some claim it isn't needed any more but to me it makes a noticeable difference.

G-sync... all i can say is wow...

Bought a 35 inch superwide running g-sync at 200hz and it feels so much different.. movement in games is so smooth..

Is that definitely the case? In War Thunder (one of the few games where my FPS went crazy) it seems limited to 144 even when v-sync is off in-game.

Never tried ULMB, might give that ago!

RichardH754 · 31 Mar 2016 at 08:38

I heard someone had managed to get Nvidia 3d to work with this Acer monitor?

you should always always turn off vsync in game

the gsync + vsync (frame limiting to the monitors refresh) is controlled via the Nvidia control panel - if vsync is on in NVCP then it will be limited to 144, but IN GAME vsync should always be off

With gsync enabled it'll cap at your monitors max refresh rate.

In CS:GO I had the refresh set to 144hz back when I used a ROG Swift, some people will tell you not to do that as you want the highest FPS you can get i.e closer to 300 with a 980ti but for me 144hz was more than enough.

I mean it's highly unlikely any of us are going to go pro and need this mysterious few ms of input lag.

Arcane · 31 Mar 2016 at 09:30

After playing with these options for a while now I've left G-Sync on and v-Sync enabled in the CP. The difference was really minimal for me (input lagwise). I play BLOPS 2 and there was no difference in KD between the two. Now DSR is working I've been playing at 5120 res at 143fps, still feels the same to me

enigma27 · 31 Mar 2016 at 12:29

So did some playing last night with various games and love the smoothness of it all..

Might knock it back to 144hz though as cant see much difference at 200.. also 200 pushes my gfx card heat up.. even though its a water cooled gfx it still hits 70+ degrees because of the high refresh...

Used to always run V-sync on 60 hz so used to temps never going above 60.

It's no only to do with input lag

Higher frame rate = better network latency and hit reg. Because how source engine network works you want the highest frame rate.

It's a fact and even documented by valve. Don't limit your frame rate you just putting yourself at a disadvantage.

It's that a custom loop? The refresh rate is irrelevant, you should never be hitting 70c on a 980Ti under water.

What's your set up?
