ISSUE DESCRIPTION

Description of the issue:

Xbox Series X (but also reported by several PC users in the aircraft feedback thread)

NAMC YS-11 exhibits a constant stutter/frame-drop every 3-5 seconds in both 2020 and 2024. This stutter is continuous/predictable and begins as soon as the aircraft is loaded, regardless of location, flight conditions, or avionics selection.

It is so consistent for me that I can perform a count of 4 seconds exactly, and hit the stutter every time.

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)?

Every flight with this aircraft.

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue:

  1. Load NAMC YS-11

  2. Observe stutter/frame-drop every 3-5 seconds

YOUR SETTINGS

If the issue still occurs with no mods and add-ons, please continue to report your issue. If not, please move this post to the User Support Hub.

What peripherals are you using, if relevant:

[PC Only] Are you using Developer Mode or have you made any changes to it?

[PC, MSFS 2020 Only] Are you using DX11 or DX12?

[PC Only] What GPU (Graphics Card) do you use?

[PC Only] What other relevant PC specs can you share?

I am experiencing this as described on PC with MSFS 2020.

I know this is an xbox thread and I am PC but I and another have already reported stutters in the YS11 thread. So the stutters are not only Xbox - therefore it must be MS/Asobo issue. Oddly, they were not there yesterday flying around Japan but when I flew in Madagascar, no airports or cities in sight, there were stutters. The cockpit also loads in each time you go back into it from outside.

PC, steam, 2024

Same here.. (PC, Store, MSFS2020) periodic stutter every 2 or 3 seconds with the namc. seems to be something in the system of the aircraft. the namc is the only aircraft having this issue.

Also, I could not turn the aircraft off, because the Battery switch toggles between Battery 1 and Battery 2 and not turning both on or off. Found this using the debug window in developer-mode–>behaviour–>systems–>electrical-system.

Luckily I could work around this by assigning the according variables on/of for both battery using external software (AxisAndOhs), but inibuilds/Asobo should also fix this

Hi, they usually don’t look at a second bug report in a thread that doesn’t have the right title. Check if there is a battery one or make a new one.

It may also be worth noting that there is a Support section for the YS-11 on the iniBuilds forum. I have no idea whether it’s more effective to post issues there or here, but I figure doing it in both places will have the maximum effect:

11

I have no such issues. I am using msfs with no add on scenery, an FSHUD.

12

This one is a doozy… We’ve got 13 votes here, and a few comments in the official feedback thread, so obviously not an isolated issue. However, I’ve seen absolutely no mention of this on Ini’s discord, or in their support forums. Really bizarre as it seems to be a cross-platform issue (both Xbox and PC users), but it doesn’t look like it’s happening to everyone universally. Could it perhaps be an addon conflict somewhere?

Unfortunately this makes it all the more unlikely that it’ll be fixed or prioritized in any way, which is a shame because this is really the only thing really detracting from the aircraft’s experience for me. Otherwise it’s lovely!

13

The only add on i have is navigraph and a few Marketplace planes. PC

14

Not that I had any expectation that it would be, but just confirming that this issue was not addressed or fixed in today’s update. The persistent stutter/frame drop is still present as before.

15

i can confirm that i have the same bug. stutter every 2 or 3 sec.

16

i wrote on the ini discord channel and i send the video they request. comment on support discord channel if you want

17

Performance on this plane is still atrocious. Getting that consistent stutter every 5 seconds.

18

Unfortunately it’s highly unlikely it’ll ever be fixed. Ini said on their Discord that they have been unable to replicate the problem on their end, and for some reason it doesn’t appear to be affecting everyone. Until they are able to replicate it, there won’t be any action taken on a fix. So, sadly, this plane will continue to sit in my hangar.

19

Same here, its fine for me.

Ryzen 7900X3D, RTX5080, 64Gb RAM at 3440x1440.

ISSUE DESCRIPTION

Description of the issue: The NAMC YS-11 experiences a large stutter ever 4 to 5 s which lasts about 2s. The propellers stop turning and the aircraft just hangs for 2 seconds. This begins from the moment it starts to taxi.

Since my ps5 is a pro, and there are no other games on it and the other aircraft do not experience this, even the airbus is ok, it must be a graphics glitch connected to just this aircraft.

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)? Every time I have flown NAMC in ps5.

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue:

  1. Taxi or just take off with NAMC

  2. Large stutters just start off straight away.

  3. The propellers stop turning and the aircraft freezes mid air.

  4. The sound continues. There is no change to the engine sounds.

  5. It never stops for entire flight and it doesn’t matter which airport it takes off from.

  6. of course there are no add ons because MP is not open.

I came here to report this , it is happening to me on the PS5 , kinda makes flying it a miserable experience and very disappointing considering it was a payed plane after buying the Aviator edition…

I noticed if i goto outside view the cockpit reloads aswell when i re enter the plane , hopefully it will be fixed.

I was thinking maybe it was due to it being streamed on PS5 but it is happening on PC also so i guess not?

22

I know, so sad it occurs with htis plane.
Another pilot has suggested it is because the PS5 does not have enough RAM???

23

The ps5 has 16 gb ram…. The msfs24 runs also on an xbox series S with only 10 gb of ram… it’s the ram management, the garbage collection and the platform specific optimization that matters.

If an xbox series S with 10 gig can run the msfs, than a ps5 can run it for sure.

24

Ok a very interesting thing just happened , i took the plane for a quick flight and the microstutters happened every 4 or 5 seconds as normal , i landed changed to another plane and got a low memory warning .. it has never happened before , so MAYBE it is something to do with memory on the PS5?

Memory leak or something like that perhaps? I really think this should be looked at as it is still on sale , i kinda wish i did not buy it now as i never even considered it might be bugged like this…
