Periodic Micro Stutters in multiple black square aircraft
-
Sorry that you're experiencing something like that. I can't recall anyone reporting that symptom with my aircraft in the last few years. Perhaps someone else will post here with something else that could help us investigate. Given that it's the render thread, the issue isn't likely to be anything I have encountered in the past with avionics or systems code. The only thing that comes to mind is a BIOS setting that some of my beta testers for Starship discovered that could make a significant difference to periodic hiccups. Also, are you using any third party applications alongside the simulator, or in the simulator, like an AI traffic, ATC, passenger, or even camera application? Sometimes those can create unexpected outcomes.
@Black-Square what is this bios setting you are talking about? Resizeable bar?
should reBar be enabled or disabled in your opinion for msfs 2024?

@Black-Square Ok so i just tested with an empty community folder just with the TBM (only thing still loading are the scenery stuff i bought in the MSFS marketplace becuase these are not in the community folder, but i doubt it's scenery causing this anyways), and unfortunately still the same perdiodic stutters. oh and sorry my mistake i was wrong, it was the "Graphics queue" doing something every second, not render thread. mixed that up, sorry. you can see it in the screenshot where the graphics queue has these yellow small spikes every second, and when it's doing that i am "limited by render queue". but as i said, that is not happening in other add on aircraft.
as you can see my vram is fine (which would be an explanation for this) and even if i load the "vanilla ini builds a310" (which is very badly optimized) i don't have this weird graphics queue spikes. as i said, this only happens on black square aircraft. it's like the tbm does something every second to this "graphics queue". and it's also not permanent. it can stop for some seconds and than start again. but it's very annoying and breaks immersion.
it's really a pitty because i think the black square aircraft are awesome and i love them, but like this it spoils it for me
the sim runs SO SMOOTH for me for every other aircraft and airport. it's definetly not my system or wrong msfs 2024 settings/graphics settings because then i would have the problem with other aircraft too. (as i said i also fly complex stuff like fenix, pmdg, ...)
and to be honest, i don't want to mess with BIOS settings, because the sim, and other games work great and i don't want to break other things too.
only one thing i could imagine, maybe Resizeable BAR could cause this? i didn't touch any BIOS settings, but i looked into the Nvidia control panel system information and it says rebar is on. maybe this is causing this? i don't want to mess with bios tho, unless you think this is most probably the cause for this.hope this information can bring some light into this.

No issues with stutters on my end. May be a dumb idea, but try limiting your frame rate to 60fps. You'll still get 120fps with frame gen and it might free up some overhead for stutters.

@dave_pilot I find it very strange that you only see studders in blksqr, but not in more performance demanding aircraft like the fenix or 777... When I had performance issues I did this. You can try if you want:
-Ran DDU and reinstalled an older confirmed stable driver from scratch since the latest Nvidia driver is pretty broken last I heard. Say Intentions Recommends 581.80 and that is what I'm on right now with no issues:
https://www.nvidia.com/en-gb/geforce/drivers/results/257569/
*run DDU with internet disconnected to ensure windows doesn't install any compatibility drivers:
https://www.guru3d.com/download/display-driver-uninstaller-download/
-Try turning off G-Sync under monitor technology in Nvidia Control Panel for MSFS2024
-Delete ROLLINGCACHE.CCC in %AppData%... \Local\Packages\Microsoft.Limitless_8wekyb3d8bbwe\LocalCache
-I also recommend running TAA instead of DLSS and turning on Dynamic Settings in MSFS graphics settings and in Online settings set Rolling Cache to 32GB. -

i then thought maybe it's because i have TOO many fps in the tbm, but when using "cheap" vanilla stuff it does not happen either.
and limiting frames didn't help as i already said. so the problem is also not a high fps count.i don't want to mess with any driver stuff right now, because as i said, i don't want to risk that other things might break, because in general i am very happy with the sim and its performance and i don't want to introduce problems to something that works well right now. and i also don't want to sacrifice DLSS for 1 plane tbh.
yes, i already tried deleting the rolling cache file. and created a new one. i always had a rolling cache of 64GB. problem still persists in the tbm and i disabled gsync in general because i don't like it.
at this point i think it might be just my exact system configuration reacting allergic to black square aircraft. lol because i can't explain why it happens and as it seems no one else can. i don't even run anti virus software, only windows defender so i am basically clueless at this point...
i also don't run other software in the background. no browser, no background tasks, no steam, no iCue, nothing. just msfs.
for now i just give up and fly other stuff until the next sim update and then try again. maybe this will change something in the background which resolves this. it's a pitty because i would love to fly the tbm, but at this point as it seems to be my only option.

@dave_pilot I don't understand what you mean by "sacrifice DLSS", it is a buggy AI upscaling mess that causes higher VRAM usage, horrendous ghosting, and crashes... Also latest Nvidia drives are confirmed to cause audio driver crashes, audio stutters, and frame stutters while using frame gen in multiple games including msfs2024. I do not know if you are new to black square and have always had these issues even before frame gen, but as of right now, roll back to 581.80 and only update when drivers are confirmed to not brick your PC by community in the future. Nvidia cards have been a nightmare to get working without constant issues since release of 5000 series.

@SadBucket quite frankly i don't have any issues other than black square atm. i don't have any crashes, audio stutters, vram problems, frame stutters with frame gen and dlss and latest driver. (only the slight ghosting on displays with dlss, but that's no big deal for me) i couldn't be happier atm with the sim and for now i just quit black square and fly my other planes which work fine.
i may sound a little bit ignorant here, but i started simming back in fs9 days and i am tired of the constant "fixing" and "optimizing" so meanwhile i just fly the sim and if problems occur i quit on that add on quite qickly and fly other stuff.
and i will definitely not start messing with drivers or settings now or something else which potentially breaks all my planes.
i mainly started this thread just to report a bug and ask if there is maybe a common solution for this or something else but as it seems there is not, i give up for now and try after the next sim update or something like that.
thanks for your help! -

thanks for your help!@dave_pilot I have been flight simming since FS9 too and have avoided trying new experimental AI features for the same reason. Good luck

@Black-Square i investigated a little bit more into the issue in SU5, because i thought maybe it fixed itself because of the new multitasking but unfortunately i still have the same issue. periodic micro stutters coming from the graphics queue.
but i found the following: if i increase the "Off Screen Terrain Pre-Caching" value it gets worse, and if i lower it, it disappears. so maybe this give you some hint in a direction?
again the problem is: periodic (like every second) microstutters in the TBM850 (and basically other blacksquare aircraft). the graphics queue goes from around 5ms to 15ms every second. which introduces microstutters. ALL other aircraft work fine. PMDG, fenix, taogs hangar, comanche, learjet. it only happens in the blacksquare fleet. sometimes it's worse, sometimes it's less, but the graphics queue is definitely behaving strange in all black square aircraft. it also happens when i have the display refresh rate at a lower setting.
