A300 stutters every 10-15 seconds

[PotatoSalad]

Hi!

Noticed it on both versions of the A300 (V1.0.0 and 1.0.1 - worse on the latest version). Stutters last for 1-2 seconds and occur every 10-15 seconds. Noticeable sound from my hardware when it occurs and there is a dip in GPU load. Does not occur with any other third party plane. Community folder is almost empty and occurs both on the ground and in cruise. I've tried to amend/reduce settings but makes no difference. Normally doesn't occur at first load up but does by the time I arrive at a destination. Tested on both long haul and short haul which made no difference. 

Running a 4070ti, 5800X3D, 32GB ram, 1080p. 

Thanks

Sir are you running your sim settings on? Have you tried to run an older version of gpu software? Try rolling it back a few cycles and see if this will eliminate that problem. I am not sure about Nvidia cards but shouldn't there be a settings that prevents screen tear and lagging? So e have stated the 8K texture might be the cause am not sure about it. I don't have those issues.

I was experiencing extreme stutters on an i7 13700k and RTX 3080, especially when panning or changing views. I installed the optimized textures and that helped a lot.

I had the same issue and installed the optimized textures, that help a lot indeed.

And I have a rather good PC: i9-13900K, 128Gb DDR5, RTX 4090.

Same issue here with i7 12th and RTX 4070Ti, but after downgrade the textures that helped, but after landing in a third party airport, the problem came again... The VRAM uses is too high... With third-party aircrafts it maintains about 6~8gb, but with the A300 stays on the limit!

I've created a post in Suggestion, and shared videos, hope that helped the staff...

[PotatoSalad]

Thanks for the suggestion; I shall give the optimised resolution pack a go and report back. 

@Rodrigo Martins I saw your post and video, and that is exactly what I have experienced. 

[PotatoSalad]

Update: Tried the optimised resolution pack and it's made no difference to the stutters. 

So, it's still an issue regardless unfortunately. 

[Miro]

I’m sorry that didn’t help. 

Installing those textures is not very intuitive through the INI manager. To be sure, check to ensure the folder of those textures exists in the community folder. 

[PotatoSalad]

Thanks for the suggestion. I checked and the low resolution textures were installed within the community folder.

Same here. Was thinking my 2080ti might be showing its age, but this is a new problem for me. I only installed GPU-Z because I suspected high usage. Sure enough most of the time its pegged at 99%. And I double checked that the low res textures are indeed installed.

Update:

Been flying stutter free all day until the sim started to get dark - stutters came back. Rolled back the time by 1hr to daylight and stutters went again. So I think the stutters are related to night ops.

Was there a fix to issue because I'm experiencing the same issue even after I downloaded the optimised texture. By the way do they just install automatically after the I download each single airline? It's hard to tell difference.

Same issue here.

Every 15 or so seconds something is running in the background affects my frame time while using this plane. Also observed on the A310 when I used to fly it. Never happens on any other AC that I have

[PotatoSalad]

I think I remember experiencing the same issue with the A310 also. 

I've tested this with both the optimised textures and the high-def ones, both experience the stutters as described during night ops. We've not found a workaround, so will need inibuilds! 

FYI you can check if the optimised textures are installed properly as they show in the community folder and is noticeable in the cockpit (try looking at the seats, panels etc).

Is anything spiking in task manager when you experience these stutters?

[PotatoSalad]

Nothing else jumps out at me, nor any other program. The only indication is GPU usage, which normally with the A300 sits around 60%, and with the spikes it decreases to 30% (forgive me I'm a bit of a layman in this area!). @Maxis screenshot is probs best to use.

Nope. Went there first thing to check. Nothing is spiking in there.

Same problem with me ,if I leave the AC in cold and dark for a while,and pan around  close to the engines the fps drops (stutters), but in the cockpit is fine.

Started noticing this (or atleast something similar) today. Fps drops/stutters at certain intervals. Starts happening only after turning on the batteries and stops if I turn them back off. Also noticed that it doesn't happen when time in sim is set to daytime. It only happens during sunrise, sunset and nightime (or atleast is more exaggerated then). It only happens in the a300. In the dev-mode fps counter ingame I can see that there is a spike in CoherentGTdraw for the duration of the stutter/fps drop.

Ryzen 7 7800X3D, 32gb ddr5 ram, rtx 4090.

That's pretty much it. When it happened in the A310 it started the moment the batteries are pressed but because i dont fly the A310 much i never bothered to report. Also, I have been doing night or early morning ops in this present A300 so i it meets your second criteria. I will do a day flight to see if i get those dips to my frame time that i reported above. Thank you for going further and locating that spike in CoherentGTdraw .. maybe the devs can do something with that additional information to identify possible causes.

Along of having the stutters issue I'm also experiencing an completely shutdown of the simulator right after I pick the aircraft from the menu and before it loads the departure airport the sim crashes. 

[PotatoSalad]

Has anyone tested the stutters with V1.0.2?

Hello @PotatoSalad I'll test now, do a short flight at dusk

[Rodrigo Martins]

Stutters still present on V.1.0.2 😭

On task manager, always the stutter happens the process "System" up from 0% to ~14%

Try deleting your rolling cache and see if that helps at all.  I am just curious about that.

Also try using the optimized textures from the app itself instead of the high quality texture.  I have downloaded these and it has improved the fps. Also on that note try to roll back your gpu drivers a notch.  DX12 if this is selected can cause some issues.
