Performance degradation over time (MSFS 2024)
-
I'm on my second flight duration over 2 hours, and I'm experience performance degradation in the end of the flight. I do not have this issue with other add ons like PMDG, Inibuild or FSlabs. High or low altitude dense or sparse scenery I'm getting stutter with Starship give or take after 2 hours in flight. I'm suspecting some kind of memory leak withing Starship code. Does anyone else experience performance degradation during long haul?
P.S. I'm on SU2. I9 13900KF, RTX4090, 64G of ram

I've completed a touch over 5 hours in the air twice yesterday with no issues in 2024. This was about as far as I could stretch it on range. I've seen no issues with performance in the starship at all - actually probably the smoothest performing of all the planes I own.

Someone else also had an issue, try this

@Qazme did you use real time or accelerated time?
All my flights have been in real time. As far as stutters go there's a couple MSFS related things, SU3 has memory mapping on which does cause usage to rise over time - last I checked this was still enabled for SU3 from what I've gather from feedback. The other would be operating your machine right at the limit of it's vram capabilities will cause stutters over time as it starts dumping textures to shared memory.
The whole reason I went to a 5090 is for the memory amount which solved any weird stutters over time at the quality settings I wanted - it would start roughly around 16GB and once it got to 17 to 18GB it would start stuttering, and 20 to 21GB it turned into a slide show for me. Mainly it was the shadow settings that caused it on my 4090, once I turned down shadows the problem went away. Running shadows and SU3 it was nothing but issues for me.
With the 5090 and the same settings the usage raised to 20-21GB of vram and remains smooth with everything turned up on triple 4K. Just something to investigate potentially.

I don't have SU3 and I don't have stutters with any other add ons like PMDG777, Inibuild A350, A2A Comanche, or FSLabs A321. I only have issue with Starship. So it is pretty much clear that its not MSFS related; otherwise, I would have stutter problems at all the times. In fact, I had a long haul (over 11 hours) in 777 real time and not a single stutter

Was just trying to help, nothing else to offer since I'm not seeing these issues. Best of luck.

Oh, I missed that there was a second thread about this. If you are willing, please go try the first and very simple change that I recommend in this thread to help me pinpoint the issue. Thank you!
