Question Micro-stutter issue since day one, new GPU hasn't fixed it ?

[stormy fairweather]

with the fresh windows install i saw the stutters before ever installing a game. i have tried different outlets, and even moved to an entirely different house while bashing my head against this. only other thing on the same circuit is my router. no change with keyboard and/or mouse unplugged. rebuilding the pc without the case i simply dont have the setup for.

one thing i did notice was that there was a slight discoloration on part of the mobo. almost like it was damp, though it didnt seem to be to the touch. and everyone i found with similar observations was told that it didnt mean anything as long as the system was firing up. and that is kinda where i a super fucking stumped; the ONLY things i have not replaced are the SSD (which was otherwise eliminated), the mobo and the psu.

now, i THINK if the issue was with the PSU one of my benchmarks or diagnostics would have flagged it. here is my cpuz report (https://valid.x86.fr/e3ev8h), and nothing there voltage wise seems off. and every thread or discussion i have found on faulty mobos they simply dont POST. though i found the same thing with processors. and my pc POSTs. in fact, if you were looking at it from about 20" away you would probably never see the stutter. but you cant game from 20" away.

removed 2 of the ram sticks so i wasnt mixing. updated report (https://valid.x86.fr/wm1cpa).

still stutters. can anyone point me to a way to eliminate either the psu or mobo? i simply cannot imagine any other possible fix at this point.

It's very very difficult to further test this. If you try with another motherboard of the exact same model and the stutters are gone, then maybe something, somewhere was screwed up on the mobo. If it still stutters, you could try a different model entirely.

It doesn't seem like a software issue. More like some very odd electronic issue buried very deep.

Or it may not be the mobo at all. The damn problem looks very much like a write (to SSD) interrupting everything for a split second.
I wonder if there's some way to pin this down or eliminate it as a cause. Read/writes happen all the time and they are never noticeable except on very old systems. I recall having a machine that was not very good, and when playing games i would get the occasional stutter if windows decided to access the HDD for some reason, while doing it's regular OS things.

So i may be off, but there may be some process running that from time to time grabs too much of the CPUs time, and causes your stutters.

One other thing to try if possible, is to boot Ubuntu/Linux. Try gaming with a different OS. It might clarify if the issue is caused by Windows.

thing is... this isnt something that comes and goes. right now, as i type this, the image on my screen looks great. exactly what i would hope for. but as soon as i scroll up or down it looks wrong. it FEELS like windows is running at 30 fps while my monitor is running at 144hz without vsync. constantly. i can open the task manager, see that my SSD is at 0% utilization, and scroll up/down and witness my stutter without the SSD usage moving.

remember those old LCD monitors that didnt quite seem to clear the frame before the new one was rendered? so even though the pc was outputting decent fps it didnt really look or feel smooth? almost like there are two frames being rendered simultaneously. this is why i replaced the monitor first. its hard to describe and impossible to show. any recording i take on my pc looks fine to anyone else, and any recording of my screen looks fine on any other devices. because in either case it isnt being rendered on my cursed system, which was why i replaced the video card.

at this point, i feel like if i order a psu and mobo BOTH i will STILL fail to resolve this damned stutter, and as a bonus i could take all the spare parts i would have at that point and build an entire second system... with the same damned stutter.

that my switch continues to look great at 60fps (or lower) both infuriates me, and assures me i am not simply insane.

Wish i could say for sure what's causing this.

If the motherboard is under warranty, try to treplace it. It looks like you have to build on a new/different motherboard.

i hope you do find the cause. Don't throw that mobo. It's magic.

with the new processor and video card, many of my games seem to run a little better. sacred 2 is actually running at decent framerates, and that game is harder to get running than crysis was when it earned meme status. might actually be able to play that game for the first time XD.

HOWEVER... the stutter at lower fps remains. games at 60fps still feel very bad, videos still seem to have some kind judder/stutter, and while scrolling in windows does seem smoother than before, it is not as smooth as it should be.

so basically, the system is running games better than it is running windows. is this information potentially useful in isolating this issue?

edit - another data point that might be of use. grim dawn has cutscenes in the same style as witcher 3's loading screens. psuedo still images that kinda shift about (if you played either you know what i am talking about). anyway, the games themselves run perfectly; 120fps and perfectly smooth all the time. however, the cutscenes in grim dawn and the loading screen in witcher stutter terribly. genuinely painful to look at and reminiscent of the stutters i see outside of games and in all videos.
