My GSYNC experiences

Thanks for the insight James j ;)

most of what you say tho is how i felt going from a 60Hz monitor to my 144Hz monitor so for me it's hard to read into what the Gsync is offering over and above 120/144Hz??

thanks for your time writing this.

I've owned a BenQ XT2420T (120hz) and a BenQ 2411T (144hz) monitor and played the games I've mentioned so far on each of them. Theres definitely a difference between having gsync on and off, regardless of the monitor imo. As I mentioned earlier, its hard to describe what the experience is like, but having the monitor only scan the frame when the graphics card has one available means that you see the frames as soon as they are rendered.

this throw a spanner in works for me now, had my heart set on getting that new ultrawide LG but your gsync experience sounds awesome for gaming

Due to the issues with my 1440p iiyama, I was considering 4k, but gregs review really turned me off it due to text sizes, plus I was concerned with my 780 tis vram being a potential limiting factor. Due to that, I started looking at pure gaming alternatives.

I'm genuinely surprised how effective it is though. I wasn't expecting to see such a big difference, especially in FPS.

That's alright, cheers for sharing your experience with G-Sync - very helpful for people (including me) considering going in that direction :)

Assassins creed black flag is smooth but not ideal if I'm honest. The animations are no were near as smooth as other games, so I'm guessing they've been written to account for vsync lag, which is noted by Nvidia as being the one and only situation were gsync doesn't work as it should when it comes to games (the other being 24 frame per sec videos, as that would equal 24hz, but I think this might have been resolved, need to check though!)

The animations in this feel a bit "juddery", yet enabled normal vsync or disabling vsync and disabling gsync too, makes the animations look as you would expect. Due to that, plus the 60 fps cap, I wouldn't use gsync in this game as it feels weird.

It's probably not going to be fantastic in certain games where the engine is capped unfortunately! I've seen AC4 without the 60 FPS cap and things start to go horribly wrong. It happens all the time for me as with three 780tis it can cause some really hilarious physics if the FPS spikes too high lol.

Ah, that's fair enough, thanks for testing it - guess GSync can't work perfectly for everything! Still, the rest of your write-ups from other games sound encouraging, very tempting to get one of these monitors now...

James do you use Vsync in other games before Gysnc? or you play with Vsync off?

How does say BF4 compare to having Vsync off and Gsync on?
Click to expand...

To use gsync, you'll want vsync off in games and gsync selected in the nvidia CP. Depends on the game mate in regards to using vsync, especially when I had my previous 144hz monitor, as the input lag was noticable with vsync on, meaning I couldn't really enjoy online FPS games unless it was disabled.

Now, having gsync disabled + vsync disabled (just like most people here), lowers the lag definitely, but I get screen tearing and stutter on BF4. Enabling gsync whilst keeping vsync disabled ingame (as mentioned first) lowers the perceived lag even more (seriously) and removes stuttering and tearing completely.

Due to that, theres definitely a difference between gsync on and vsync off settings, especially for users who have multi gpu setups and can pull off some crazy fps without vsync slowing them down, as the more fps, the bigger the falls are in regards to stuttering (say 200 fps in BF4 normal, then a few explosions and your fps hits 90 for a split second, you'll stutter. You won't with gsync)

Have you compared single/dual card performance?

The major selling point of Gysnc is smooth performance without the need for high end hardware.

A single 780ti doesn't equate to lesser hardware, but if you could max out C3 for example on 1 card, mins should be well under 60 fps, if it performs as it's meant to then it's looking good as a Gysnc monitor is cheaper??? than a 780ti.

I've not yet no, but I'll have a go at that on friday or saturday, as sadly I've got some work to get on with now. You are right about the major selling point, but the nice thing for people with high end hardware is completely eliminating stutter and tearing, whilst improving latency.

Cool thanks
Thats the great thing about Mantle the frame drops are much more smoother I feel when using Mantle on BF4. Unlike DX11 when the frame rate drops like you said you kinder get a slow down effect.
On Mantle this isn't something that happens, from what I understand its something to do with tighter frame latency. You can see that from my Mantle+BF4 videos when one sec I running 180fps and next 120fps it just continues the play smooth.
So yeah I understand what you mean on frame stutter. One Reason I can't wait for DX12 or Mantle to be enabled in more games.

That low latency is what you get with gsync also, so mantle will give you part of the experience already. Its the complete elimination of tearing and stuttering that you'd probably notice from your perspective.

Yeah that great enjoy seems Nvidia could have real winner here. Am still hanging on the fence though I think I would have to try it first.
AMD are also coming with something called FreeSync I be buying a new monitor soon once I see 1440p 120hz display so might hang in there to see how freesync comes along.
