1.29.30.0 : sometimes heavy stutters at approach

[Adrian123 1,015]

I found any kind of Live traffic causing APPR stutters. Disable it and it goes away.

Right now this is the main issue for me and sometimes it's random and unpredictable in that there may not be a lot of traffic activity and yet the frame rate impact can approach over 20%.  I wish there was a toggle to turn it off w/o having to stop the sim.  I guess that is where AI Companion comes in if I could only find out where to download it from!

Here I have the RD LIRN airport and use PSXT live traffic + RT + AIG.

Thank you willing to test .

Try without AI traffic. Many people reporting stutters when using AI traffic lately. I turned mine off and have no stutters now.

Did y'all experiment with an empty Community folder? I emptied it and the stutters at approach were gone. The culprit seems to be Manudesign powerligns (at least the April 22 version, I might try the newest one later).

I have this stuttering as well.  From my tests, it seems to be AI traffic related.  The reason your night flight was smooth is because there was less traffic to load.  The more traffic at an airport, the worse my stutters have been.  Turned AI traffic off, its smooth on approach again.  It sucks to have to fly in an empty world, but its something asobo needs to figure out.

If I fly at late dawn, daytime and early dusk then I can make 3-4h flights without any issues.

Including AI traffic.

The framerate degradation starts after about 1h 40 min when terrain nightlighting is on.

I'm not on beta - but yes turning off all Air Traffic (Live and AI) has helped smooth things out tremendously for me.....I'm finding I dont miss that much myself......but still saddened I have to turn off features to get what I had in SU10.

Yes, that one gave me stutters too, had to uninstall it.

Sometimes it is hard for developers to know if their addon still is working 100% without issues after a SU…

That one was causing stutters even before the SU.

Today I did 2 flights in the dark from Amsterdam to Naples.

Giuseppe ( Prosim user ) pointed out that after testing he did a few months ago he thought that it might have to do with the effect files used for lights.

So I disabled all external lights after take off and turned the needed lights on just a few minutes before touchdown. 
Result : no stutters at approach

Anyone suffering from this could try the same and see if it helps.

It might be that the ac effect files for external lights are causing a framerate drop over time. And if you have you fps locked you won’t notice it till approach …

I noticed the FPS degradation last night for the first time. I was flying from CYEG to MMUN with AI and addon scenery at MMUN and I was flying the PMDG 738. On the approach there is noting but mangroves, and Cancun is pretty light on FPS even with AI. I've landed at MMUN a number of times, and I haven't had any issues. The only thing new was REX Accuseason, so I'll investigate that further.

Did the same flight twice now without stutters after I started using LSLC :

 

I did not try the first tweak, just LSLC…

Do you need to go to the app and press the button in the middle of the flight or is it all automatic?

LSLC

What is that?
