Performance Issues with Starship – Sporadic FPS Drops
-
Thanks for showing exactly what I have been asking to see! I finally have a chance to spend some time on this later tonight. I will let you know what I find. At least you can continue your flight to landing after pulling one circuit breaker. I know that's far from ideal, but I'm glad there is some solution that at least gives you the satisfaction of a smooth landing while I work on the problem.
Did you try the BIOS change suggested above? Specifically enabling C-State Control? It would be interesting to see if that could change the outcome, now that we've collected some data.
@Black-Square Yes, I enabled C-State Control, but it's still the same. At least I can continue the flight by turning the circuit breaker off and on
. Thanks for looking into the issue.edit: I discovered something new — even if I turn off ND No. 1 and turn it back on, the FPS starts dropping again after a few dozen seconds. So I have to turn off the breaker again, but once I turn it back on, the FPS drops again after several dozen seconds. Unfortunately, I don’t have a recording of it because something went wrong and it didn’t record.
I also discovered that the FPS starts dropping for the first time between 55 -60 minutes of flight.

I have no idea if this is related as I have a 5800x 3d without C State but on tonight's flight on landing, the fps dropped to 10fps and this has never happened before. It could just be the sim, the servers etc but thought I would add here as it was in the Starship.

@toby23 If it was maybe 10-20ft off the ground and recovered shortly thereafter on MSFS 2024, this happens to me constantly with every single aircraft. I thought we were done with severe stuttering in the flare with FSX, but I guess not.
-
Yes, this was exactly what happened.
The ground textures turned very blurry in a small circle around my aircraft too, maybe a 10m radius.
The only add-on I use that changes LOD is AutoFPS but I use AutoFPS on every flight and have never seen this behaviour before.
Always a giant leap forwards and then fall backwards with this sim. I can't wait until it's more stable.
Thank you for your feedback and good luck with your Simisms -
Unfortunately I still has this issue randomly coming up even after 1.2 . It only happens to Starship and I believe it has to something with custom avionics.
Recently I upgraded to RTX5090 thinking may be related video memory issue obviously its not . I tried several long hauls routes without any issue. Then intermittent stutter came back - every second micro stutter. It usually happens enroute and all the way to the landing. I program FMS manually typing each waypoint using keyboard. The only thing come to my mind is something to do with waypoint programing.

I can confirm this but I can actually reproduce it. Flying from EETN/26 N0302F360 DCT ORTAX DCT LOGNA P31 KEDUX DCT EMGAR Z717 BODLA L733 LOLPA Z14 ERAKU DCT EDAZ/25.
Did it write and it happened twice. Also on 1.2.Funnily enough at the same time when entering briefly touching Russian airspace at Kaliningrad.

For me It only happens to BS aircraft. I don't have performance degradation with A2A or other add ons flying 3-5 hours blocks. Performance drop usually doesn't happens until after few flights. I bet my money on some kind of tear and wear code that overtime leaking memory or creates to many background processes that degrades performance

@sdflyer I would love to believe this too, since that would make it not terribly difficult to track down and solve, but many hours of testing and collaboration with the several people who have contacted me with performance issues in my aircraft have yet to yield a definitive answer. Each case has ended with some simulator or system setting solving the issue, or finding that the issue existed in default aircraft and waiting until the next sim update.
While the failure system is an obvious first place to look, it's also the easiest to test, and we have found no issues there. I also might add that the reason I use JS instead of WASM is because of its resilience to memory leaks, and other such issues. If you had any interest in disabling the failure system to test for yourself, I would be happy to walk you through it.
Starship, being by far my most complex aircraft, exhibited some early performance issues with my beta testers, which had similarly unrelated cures. Most often, a BIOS setting change made a world of difference for many users, and others found that a virus checker was the cause. Whenever I was able to examine performance degradation on specific flights, the symptoms were very specific. Every-other frame would be impacted, and limited to the "manipulators" thread of MSFS. We don't have any documentation on what exactly this means, but I was able to demonstrate that it has something to do with the cockpit interactions, which makes sense, given the name. Unfortunately, this would lead me to believe that it's a simulator level bug, and not necessarily something I can solve. Perhaps there is something that I'm doing to exacerbate it, but even deleting large sections of my interaction code did not have an effect.
Long story short... I have spent lots of time over the years trying to track down performance issues with the small number of users who experience this problem, and the solutions have always been on the system side thus far. This is not an excuse for me to stop looking, but it's merely what I have to report so far.

@Black-Square
I’m happy to help . I’m running i9 13900 , gtx5090 and 64G ram . I tried several add ons side by side to compare performance degradation. So far the only trouble I have is with BS that why I assume it has something to do with wear and tear. Perhaps some Aosobo API causing it .
