FPS Degradation on Long Flight
-
Just a question for everyone. How many of you have Toolbar Pushback installed? Apparently it can cause this exact issue with certain addons, and it just so happens that my Starship longhaul was my first flight after installing it. I've uninstalled it and will see what happens, but I'm just wondering how many of us having this issue are also using that addon.

I also have Toolbar Pushback installed. I'll try with and without and report back if I see the FPS issue again.

I wish I could say that removing toolbar pushback fixed things, but I can confirm that the issue is still present without it. It happens after Starship has been loaded up and operated continuously for around 8 hours. Just did Gander to Keflavik, then Keflavik to London. Each leg about 4.5hrs, with an hour on the ground in Keflavik. Right around 3 hours into the second leg, performance began dropping steadily. Maybe a memory leak somewhere?
-
I never used Toolbar Pushback to begin with and still have degrading FPS and/or MainThread lag spikes.

Okay, anyone who wants to test this for me, here is the first thing that I would try. It's extremely simple.
Locate
...\bksq-aircraft-starship\html_ui\Pages\VCockpit\Instruments\NavSystems\bksq-aircraft-starship\MFDmapConfig.jsonChange
preventLabelOverlaptofalse. That's it.There is a chance that you will have to drag the aircraft's layout.json on top of the MSFSLayoutGenerator afterwards, but only in MSFS 2024.
If that doesn't work...
I have already heard confirmation that removing both ND's and the MFD from each panel.cfg eliminates the problem, but it would be nice to get some additional confirmations that this is indeed where the problem lies.
To do this, you can either remove or comment out the three [VCockpit] entries in each panel.cfg (or in only one aircraft, if you're feeling confident of which is which) that include "MFD", or "ND". No renumbering in the file is required. Comments can be made by beginning each line with
//or;.After that, I'm afraid that it will take some volunteers to solve this one again. If any of you have already written to Just Flight about the waypoint deletion CTD, and also experience this problem, then let me know.
Much appreciation again. As you might imagine, these bugs that only affect some number of users, and none of my beta testers can be a real pain to track down, so I am very thankful for your willingness to help.

That will simply remove the ND and MFD from the aircraft completely (you will get white screens in the cockpit, which, if I'm not being too cheeky, is a great excuse to practice your reversionary modes). Like I said, I already had confirmation that the problem lies with the ND or MFD, but I would like to have more than one data point.
The first, extremely simple test would rule out one thing that I changed/created in the MFD map, but not the ND. If it doesn't fix the problem, then I will know where else to look.
Of course, it makes little sense that this is another problem in Starship that only affects some users, but that's software, I suppose.
-
Changing preventLabelOverlap to false (and regenerating the Layout.json) might have imprved things a bit but it might be a fluke. I did only one 2 hour hop with it. The performance issue is certainly not resolved.
Do I change that setting back to true before testing flying without ND and MFD?
Another datapoint in terms of platform:
Windows 11, latest version. 13900K, 5090, 64GB DDR5 RAM.
I already lowered resolution and settings. GPU is at 30% load. Just to make sure it's not somehow graphics related. -

preventLabelOverlaptofalse. That's it.Happy to report that I repeated the same 3.5 hour flight that previously caused lag spikes, and this time there were no MainThread issues I would attribute to the Starship rather than MSFS 2024 SU2 after applying the change. I'm cautiously optimistic for now. The sim is still running, and maybe I'll manage to do the return leg later, despite the heatwave sweeping through Europe right now.

Thank you both so much for testing! Please, please continue testing with that flag set to off. I wasted about a week writing better code than what Asobo had there, but ultimately decided that it was too heavy on performance, so I rolled back to Asobo's code. Apparently theirs wasn't much better! Ironically, I discovered that Starship didn't even have the processing power to implement that feature in the 80's, so removing it is the most realistic thing to do anyway! I don't know if that's what I'm going to do yet, but please, as many people posting in this thread as possible, please test this potential solution!

@Black-Square Okay so I once again don't want to speak too soon, but here's what I've got.
Changing preventLabelOverlap to false didn't do anything to solve my issue. So I finally dove into the BIOS and enabled C-States. That simple change has given me a MASSIVE increase in overall sim performance, and I'm hoping it's also the solution to the gradual decrease in performance after having Starship loaded for many many hours.
Im also an AMD user, and apparently AMD sees the biggest benefit from it.
Will advise, but the initial impression of the overall performance improvement is nothing short of incredible.
