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

[wiseude]

Got myself a s2721dgf (g-sync settings used are from the blurbuster guide) and noticed compared to my old 1080p144hz tru g-sync monitor the frametime is more erratic overall.

My currenty setup:
3080 driver 466.11
9900k
16gb DDR4 3200mhz
970 EVO 500GB SSD
750RMX PSU


Does true g-sync have better frametime in games then g-sync compatible?I'm asking because I saw a thread and he saw a smoother demo on the true g-sync vs g-sync comptaible so I'm wondering if it could also translate to better frametime ingame too.

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 disable g-sync and just run the game with vsync OFF. I believe you'll get the same results, meaning g-sync has nothing to do with it. It's just the higher GPU load causing more frame time variance, which sounds normal to me. The higher the GPU load, the more difficult it is to avoid frame time variance.

Another experiment you can do is run 1440p with g-sync ON on the 1080p monitor (using DSR to get 1440p.) See if you get the same results with that.

https://www.youtube.com/watch?v=2WJCqsKEncs Disabling 3d portholes does greatly reduce this from happening on 1440p to nothing/almost nothing.(on 1080p it doesnt happen at all so there's no need to lower any graphical settings on 1080p)

So this is normal?Just 2 examples of the frametime variance im talking about between 1440p 165hz vs 1080p 144hz.
Again just as a reminder temps are all below 75c/70c (gpu/cpu) and both videos are at 1440p.Issue is greatly reduced/goes away on 1080p 144hz

Yeah, it's normal in many games. 1440p is a resolution that's almost 80% higher than 1080p. That means 80% more pixels to render. This increases frame times quite a bit, and thus frame time variance is also increased.

A good way to make games more consistent is to cap their frame rate to something the game can reach the vast majority of the time. I've been advocating this for many years. A couple years ago, BNS on youtube picked up on it and made a video about it:

Edit:
The video is a bit outdated when it says that "only RTSS provides consistent frame times". Nowadays, the NVidia FPS limiter you can now find in the nvidia control panel also works as good as RTSS, both when it comes to frame times as well as input lag. So you can use that instead if you don't want to always have to run RTSS when playing games. Just go to the profile of the affected game in the nvidia panel and set the "max frame rate" setting to an appropriate value. Remember to disable the RTSS limiter if you then use it to test the frame timing.

Welp...that kinda sucks.I thought a 3080 would be able to handle 1440p 165hz (162 fps capped) np.Think il just go back to 1080p 144hz gsync then since it seems to be having difficulties on 1440p.Not willing to cap my fps on anything below 144fps :/

Thanks anyway.

EDIT:I tried lowering the refresh rate of the 1440p monitor to 144hz but I had a game that I play alot (black desert) which for some reason reverted my refresh rate back to 165hz every time I went in and out of fullscreen.I guess I could keep it at 165hz and add an fps limit of 144 instead of 162fps and see how it goes.

Is this actually impacting anything or its just because you are sat looking at graphs instead of playing games?

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..

I made the thread because I can feel the micro hitches.I don't usually play with a graph but when I feel something is "off" I put the graph up.

1080p 144hz has much better frametime then 1440p 165hz and its much less likely for any frametime spike over 14ms to happen is what I observed.Like I've shown on the video all those frandome spikes don't happen on 1080p 144hz but happen on 1440p165hz.Pretty obvious when you move the camera around ingame and it happens so I don't need a graph to tell me they're there.
