Stutter that appears ~45 minutes into a stream.
I took a log with hardware info, I read thru it and temps and percentages look perfectly normal. I'll send you the .csv file if you want to review it
i realy can not see a issue here on record/stream side
if you see "stutter" over time, check the "source" if the source framerate timings are instable then it looks later in stream/record stutter without a stutter of the stream
the stream can stable at 60 FPS, but if the source that record with 60FPS drops on record below (laggy game) then it looks laggy without laggs. if you habe a "new" display it syncs the view to the real frame rate (looks smooth) but the OBS record later looks not smooth.
displays show the GPU frame buffer so it shows 45 FPS if it drops to 45 but on play video files it show 60/120 with a rate of 60 fps that shows the 45 New pictures a second so it looks like the video is wrong
Its a simple hardware issue OBS record with 60FPS a 45FPS source so you have some "frames" with same images,on your display you not see this by the "issue" the display only refresh on "new framebuffer" (your eyes not see frames only "changes")
if you later view the video the display refreshs 60 times a second on the video framerate, the display goes 60 times a second on/off (the eye register this on/on) and it looks stutter
on the logfiles i see that the record is fine, so the issue of the stutter is the source of record, not the record itself

I've tried game capture, display capture, window capture, a capture card, and all my monitors are 60hz refresh. So how does any of that make sense. And the issue happens on recording as well as streams and happens the same way every time. The obs preview starts microstuttering then going into full stutter and about 5 minutes after that the issue is present in the stream. I've checked this across multiple devices, I've tried it with single monitor streaming, and it still happens so how could that be an issue?
Furthermore, if i were to deactivate then reactivate the source, would it not sync back up?

? the preview view of OBS stutter?
if we aggree that the "system" is OK then there is only 1 Reason for this
A Overload of CPU or GPU
you write that the load is "fine" (for mee fine is below 85% of CPU cores or GPU load)
the system performance setting is not on powersave? powersave settings can result in short down takes of GPU/CPU freq that can result in stutters without visible in "load %"

I sit well below 85 percent gpu/cpu load. Because I have an extremely capable system otherwise, my gpu and cpu usages while gaming and streaming barely break into 60%, per core usage on the first few cores may see 75 percent on the high end OCCASIONALLY but the rest stay below that, obs scales to cores better than the games do.
As for powersaving features, I've been down that road. Cstates are disabled. None of windows powersaving features in regards to cpu and gpu usage are on. My cpu stays pegged out at 4.3ghz across all cores, and doesn't dip. So the power saving features in windows and in bios are OFF

The CPU usage report as an average is not exacly, is average for e.g. 5 sec.
That is why many people say that a load lower than 85% is needed, I think even 50% may be too much.

85% is more then accurate
the basic issue is the understand of the People
there have for example a amd/Intel 8 Core CPU default there have SMT/HT active so 16 cores
85% Means max 85% of a CPU core, there look on the view and see 16 Bars that shows for simple example all 45% load
that sound first without know that all is fine, but this is wrong , related to the Job the CPU is handling all 8 cores at 90-99% usage
HT/SMT not double the power, it only reduce the time of load from Job1 to Job2
Thats the reason why the CPU is sometimes with low load more hot then with full load close to idle
work != work and load != load
its only a "something like this" display
before "insider" claim this as wrong , this is just a very simplified illustration

Still no solution ? i even get the random stutter in a display capture when scrolling around in Firefox^^
Im new in streaming and got my pc on may... im fighting with this since then and streaming really turns into a nightmare to me..

Nope, we're left in the dark with no options.Still no solution ? i even get the random stutter in a display capture when scrolling around in Firefox^^

Im suffering from the exact issue from a couple of months ... i have been streaming on YT from past 2.5 years but it just started to occur approximately from past 2 months from now ... i dont know wht changed but my stream and game runs smoothly at 60 fps and all of a sudden after 20 to 30 minutes the in game Fps starts to drop and eventually becomes unplayable until i minimise the game and restart the stream ... as soon as i stop and start the stream , both the gameplay and the stream is back to smooth , but again after 25 maybe 40 minutes the frames in the game starts to drop back really bad and starts to reflect on the OBS display aswell as the live stream .... and just like you it has started to drive me crazy with no solution anywhere .... and i can totally relate to what ur going thru as the frustration is mutual ... and im also desperately waiting for a permanent solution for it

Maybe one day there will be a fix? I can manage 37 minutes before the dreaded stutter appears on fullscreen preview. I'm not gaming or recording, although recorded video appears not to be affected, I have just upgraded my system, and the preview remains stable for twice as long, but I would like a preview screen that maintains a stable frame-rate indefinitely please. What I find insulting though, is the CPU stays under 0.5%, and the RX-580 fluctuates between 0 and 50% utilization while the fans ocassionally kick in. Overclocking makes no difference. I won't let this upset me too much, as computer issues are the norm, and we have to accept that.
