True g-sync has better frametime then g-sync compatible?

Talk about NVIDIA G-SYNC, a variable refresh rate (VRR) technology. G-SYNC eliminates stutters, tearing, and reduces input lag. List of G-SYNC Monitors.

this is interesting topic 4 me..my panel is free-g-sync comp,and on 1070FE 1440p when i set 2 ultra in nvcp frame times are not good
there are some noticable drops etc,,(same with 50% and 95% usage on gpu)

but when i set 2 on in nvcp(same on 50% and on 95% gpu usage),everything is smooth with animations no drops almost. but lag is huge,
however on ultra its kinda choppy sometimes bcs frame times but there is almost no lag at all..

on 1080p everything is ok and almost the same..

so my conclusion was like its about how strong your gpu is,and that i was just unlucky having 10 series card on 1440p..

and now this..if its the case also with 3080,then wtf
there must be some sort of solution 2 this,driver tweak,some sort of windows or game tweak,this thing is solvable 100%
we just need 2 find the way..
You talking about latency mode right?I have that off by default.

I upgraded to a 1440p 165hz after getting my 3080 and I did not think I would run into this problem tbh.I expected lower frames overall but I didn't think the frametimes would be this effected.
The only solvable thing that works that I can think off atm is getting a 1080/144hz g-sync monitor to get the smoothness back.
Another person has suggested a better CPU but I'm kinda annoyed because its a 9900k which is still pretty decent.

Another thing that seems to help a-bit is putting an fps much lower then normal like 60fps on 1440p for example but that defeats the point of getting such a monitor so im not doing that.

Also on 1440p 165hz lowering some graphical settings seems to help a-bit to reduce gpu usage which in turn gives better frametimes.It's like the 3080 cant fully handle 1440p 165hzwith high gpu usage.

If I were you I'd ditch you're current monitor and get a 1080p144hz g-sync monitor. PS.1440p is overrated.

What happens if you just turn all syncs off?

No difference.If anything now its worst because there's no g-sync.

So its probably fair to presume it isn't a Gsync issue.

Have you tried a full DDU clean wipe and reinstall of your GPU driver?

Are you using the same cable as your old screen or a different one also? Try out different cables.

Yes.I went as far back as 457.51 DDU cleaned.I'm using the cable that came with the screen.
Again.Frametime is much better on 1080p 144hz then 1440p 165hz.The only real solution so far has been to reduce to 1080p
I've encountered some ppl with 3080 that noticed the same issue on 1440p too.

big NO on this..

I am on 1440p 144hz 4 the last 5+ years.
it so much better as daily driver..
its a league of its own comparing 2 1080p..

but lets say its a personal preference..but still..

there is now a wise saying in panels world,

when you go from 60hz 2 144hz you will never go back,
and when you go from 1080p 2 1440p you will never go back

lets talk now about this specific topic,

i am certain there is something on a driver level that needs 2 be fixed
how chip used by nvidia handles 1440p and higher resolutions..

my reasoning is 4 example:

nvidia cards will produce less power or less fps on high gpu usage by margin of almost 20+ %
than amd gpus in a same class division = little known fact

so if something like that can be realistic..

first of all its unheard off
(its 20+ % free upgrade,and 20+ % in performance is like buying a newer cpu by intel or amd = proven by last 2 decades )

and second..

we can surely imagine
its somethings about nvidia coding or nvidia processing on silicon level thingy.
bcs there is no complaints about amd gpus and the way they handle 1440p and above.

That would explain why I notice a more erratic frametime when the gpu usage is at 80%+ (on 1440p)
On 1080p even if gpu usage is at 80%+ its mostly smooth but I guess 1440p is that much harder on the card where is starts to "struggle" which in insane because its a 3080 we're talking about here.

GPUs have a sensor for power draw. You can enable it in MSI Afterburner and put it into the RTSS OSD to see how much power is currently drawn by the GPU. It shows up next to the GPU load percentage.

This is an interesting sensor to have because it shows not all GPU loads result in the same power draw. Sometimes I get 99% usage but the power draw is 180w. Other times, power draw is more like 240w at 99%, which is when the temps start to really go up and the fans increase their speed to keep up with the heat.

So maybe you should investigate that and consider power draw rather than GPU load when you compare 1080p and 1440p.

I'm not exactly tech savvy enough to even know what to do with such information.
Like you said sometimes its 180w/240w at 99% and I get something similar.I still wouldn't know if its a driver/card issue tho.

I just checked the Wattage with totalwar2 on 1440p144fps high gpu usage (90%+) and it was pulling 330W with the random smaller frametime spikes.(had instances where it was pulling 300W on 99% in a different setting too like your instance)

If I lower to 1080p 144fps the gpu usage drops to 80-90% range and the wattage drops to around 300W and its smoother.

Make sure you're testing at 1080p, not 1440p. At a higher resolution (or even with different graphics quality settings) frame times will vary.

I said I did.There is a difference in frametime with the same settings.1080p144hz has much smoother frametime overall then 1440p 165hz is what I'm trying to say and I don't know why.
I expect lower fps not more erratic frametime.
You can't compare 144hz @ 1080 vs 165hz @ 1440p. On the same system, 1080p 144hz is much easier for your system to hold on a steady framerate vs 1440p. Basically meaning your 1% low's will not drop under 144fps @ 1080p but will drop below 162 fps @ 1440p. That is the reason for your stuttering issues. This has nothing to do with drivers or anything. You will never fix this problem unless you set a cap around or at the 1% low you are getting. Only then everything will be buttersmooth.

Trust me, i've been digging into this for years. And the same problem will always come back at completely different hardware. The only way to have 100% buttersmooth gameplay all the time is by capping your FPS at or below your 1% (or even 0.1%) lows.
