ISSUE DESCRIPTION

Description of the issue:Flying YBBN to RJTT, things were silky smooth until approaching Tokyo Haneda (RJTT) As I was descending to 5000 near NIFTY, I would notice a few micro-stutters when panning, no big deal. Flying the ILS 22 approach via NYLON, I as on glideslope at about 500 ft when I got a stutter that lasted more than a second. Then another at just about minimums. I touched down, and things turned to silk again.

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)? First time I’ve actually flown with 5.1 beta, but I wanted to report it immediately. I purposely flew an airliner into complicated scenery with most settings on ultra @ 1440P as a stress test.

REPRODUCTION STEPS

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

  1. Set up an eight hour flight on a 747-8F with the destination being RJTT, Free flight, live weather, real time. (I landed at 5:45am Tokyo time)

  2. Fly the AROSAN- AROSA arrival/transition with ILS22 approach NYLON transition.

  3. See what you see

After SU5, also seeing stutters before V1 and right before touchdown - only happening on the inibuilds A350.

Hi @DesertRick13

Has this issue only occurred in Sim Update 5.1 Beta v1.7.28.0 released, or did you experience this beforehand?

Cheers

I am not in the Beta, but have also stutters on landing since SU5. Before with SU4 the same plane and airport have been ok.

5

The way it presented felt different than even through the beta testing of 5.0. The stutter of over a second right near touchdown was disconcerting, and I would have reported something like that had it happened before.

6

I can also confirm a massive stutter right around touchdown with SU 5.1. Haven’t seen it like this before. This was at EKCH from Simnord, but think it’s not specific to this airport.

It’s a very heavy drop / stutter, not present at short final.

7800X3D, RX 9070 XT, 4K TAA, FG.

For me, I’ve noticed the stutter with busy airports like Narita. I’ve since flown from there to Tyndal AB, Katherine, NT, Australia, and from there to Entebbe, Uganda. The flight to YPTD was about eight hours, and the flight to Entebbe was more than 12. Both approaches were smooth all the way to engine shudown.

8

I have also been getting stutters on the ground during takeoff and within 500 feet of touchdown to the point it’s almost unflyable. Didn’t have these issues in SU4.

RTX 5090 Astral, 7950X3D, 64GB RAM, 4K, DLSS, FG

It seems the more complicated the airport, the more the stutters on approach appear. On my way in to EGLL ry27L ILS/ LAM approach, within 5 mi of EGLL, stuttered a few times in a row. Mind you, I was averaging 108 fps when this happened. Also, because of poor traffic management with default ATC, I had one Jumbo taking off right at me, and I had to go around because of a 777 taking off head of me. When I went to go around, everything froze, and I finally had to use task manager to bug out. This was after taking off from HUEN on an eight hour flight.

ISSUE DESCRIPTION

Description of the issue:

I would like to report that the severe performance degradation introduced with SU5 is still present for me, including in the latest beta versions.

The biggest issue is not necessarily low FPS, but continuous and aggressive stuttering, especially during the final stages of flight.

Typical pattern:

  • Flight may start relatively normally.

  • During descent, performance begins to deteriorate.

  • On short final, stutters become more frequent.

  • During touchdown and rollout, the simulator becomes extremely stuttery.

  • After landing and while taxiing to the gate, performance often becomes even worse.

The simulator never feels smooth anymore. There is a constant sensation that the flight is close to either:

  • a memory issue,

  • avionics black screens,

  • or a complete crash to dashboard.

This is happening even when:

  • using lighter airports,

  • using reduced traffic settings,

  • using different aircraft,

  • testing both Public SU5 and Beta versions.

Another issue I continue to observe is that airport life appears incomplete.

For example:

  • Character settings are set to Medium.

  • Airport life settings are enabled.

  • Yet ground crew frequently does not appear at all.

This was not my normal experience before SU5.

I understand that performance work is ongoing, but from my perspective on Xbox Series X the simulator is still significantly less enjoyable than before SU5 because of the constant stuttering and inconsistent airport object loading.

FREQUENCY OF ISSUE

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

Always since SU5 & SU5 beta versions

REPRODUCTION STEPS

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

  1. Complete a normal gate-to-gate flight on Xbox Series X

  2. Observe increasing stutters during approach, touchdown and rollout.

  3. After landing, airport performance deteriorates further and ground crew/airport life may fail to appear despite being enabled.

There are already threads dealing with this topic. It makes no sense having another one repeating the same posts. It will not speed up the bugfixing.

12

I don’t absolutely care. I’m on beta, I notice things, I report them here. Period.

13

Right at touchdown is the point of maximal VRAM usage because the view is a highly textured runway plus an airport of possibly big detail. You might want to make your texture detail minimal and try again.

14

If I were not testing, that would be a good solution. My entire point of testing is to leave everything I can constant and report what I find in relation to what it was in the past. I purposely put the sim to the most challenging I can (Airliner, known high-demand airports, Ultra settings) with what I have to discover and report problems.

15

where the moderators think the threads are similar enough, they combine them or link them.

16

Now why would i have to turn settings down now when we had no problems (Or at least not this severe) in SU4 ?
Sure doesnt sound like optimization is happening if the end user has to degrade their previously acceptable experience when a new SU drops.

17

This is absolutely right.

The beta is testing whether the changes made have improved or degraded the user experience. If beta-testers start changing their settings, it is no longer a fair or (more importantly) a useful comparison for the developers to consider.

I don’t know what the official position is on this - perhaps a community manager would like to comment as to whether the recommended method is to leave the settings unchanged to obtain a true comparison, and only then try to optimise a system to see the effect.

18

Since it is possible that new features or bugfixes cause a higher resource usage. This is at least a possibility, although I don’t think it’s the case with SU5. As PMDG confirmed, the clean sim shows the same performance as in SU4 with a little less memory consumption. I can confirm this for my setup.

I still suspect addons. In another forum a user has identified a bunch of addons causing stutters and freezes of 1-2 seconds. All of them were scenery updates, and most of them not optimised for FS2024. I think, users are not very enthusiastic testing with an empty community folder, so there are definitely also users in this forum suffering from incompatible addons. Maybe not all, but many.

19

Take a look in the Graphics Custom Settings and see if your Texture Resolution is set to “Low” or not. You will never tell the difference from any other setting but will chew up your GPU rendering runway texture details on landing.

You may also want to turn off Airport Services and other settings that increase detail in the airports where you are landing and see what happens, but try the texture first.

Your milage may vary. :slight_smile:

Yeah no thanks .. System was working perfectly normal before this. I do not subscribe to degrading my experience when the objective of the dev in this particular beta is to improve the sim’s performance or at worst not degrade its performance.

If i had no issues before (SU4) and im in a beta that is supposed to address stuttering performance issues and improve efficiency i am now being told to turn stuff down then please explain to me how did the sim become more efficient or performant? Especially when i know my hardware is not already being utilized to its fullest potential ?

Don’t get me wrong i know you are trying to be helpful and at the end of the day this is principles argument but this is just one of those things where i would probably decide to put the sim down for a month or two and revisit rather than degrade my experience after investing thousands of dollars on equipment. I guess i am stubborn like that. So no i cannot consider turning stuff down when i had no major issues before at the settings i am currently at.
I didn’t spend all that money and time tuning my PC to now be asked to turn stuff down. I spent that money and time so i could turn stuff up.. especially when we were at a point previously where performance was mostly satisfactory.
