Stutter warning / 2 fps drop

[Skunksx]

Hi there,

I saw some post talking about stuttering but could not find a answer on those.

__

After changing my monitor today (Viewsonic XG270Q) and building a new pc a few days ago, i wanted to do run some testufo on various presets, i always have a warning about stunttering (1+ or more).

Can this be a monitor problem or is it impossible ?

If this is a software problem, since this is a nearly completely fresh windows install i don't know where to search..

I uninstalled some useless software i installed (Asus useless stuffs) just in case. But other that...

I've got a i9 9900k with a rtx 2070 super, so i'm pretty sure it's not hardware limitation.
Bios is up to date.
Only thing is did in the Bios is to set my ram to 3600ghz since by default it was cut by half, but nothing else.

Gsync is activated (switching it to off doesn't do anything), performance mode is on on windows and Nvidia configuration panel.

I tried at 144hz and with the 165hz overclock and results a the same.

This is not a huge stuttering, but it exist and it bothers me since everything is new hardware wise.

If i can get some help here on why i get that, it would be awesome.

Here is a screenshot of my ufo test.

This is not a monitor problem. The testufo site cannot detect monitor problems (if it could, then it wouldn't need to display these test animations, it would just tell you if there's a problem .)

Stutter warnings just mean the browser sometimes has uneven timing. This test displays a browser timing graph: https://www.testufo.com/animation-time-graph

Yes, that's right, the point you make seems now obvious about the monitor.

I did the test (and did it now again) about timing graphs, and i have some spikes here and there.

Do you know where i should be looking ? I don't remembering having these on my previous setup...

Some software you have running in the background maybe. Or you have several browser tabs open.

HDD is especialist making lag spikes, each time CPU read from it, system lag party due to slow access time, low IOPS. You have one of these stone age devices installed ?



Process Explorer for Windows OS is a good software to cath lag issues, you can see process CPU usage and CPU context switch per second is very usefull for detect driver latency bugs, or software bad programmed.

Disable browser addons for testufo tab, don't forget close porn tabs
