ISSUE DESCRIPTION

Description of the issue:
Unclear pattern but when traffic should be visible there is a long freeze and CTD. Still unclear if it’s a specific model but that happens quite quickly.

First time this is happening. This is the latest FSLTL 1.5 release that works just fine with SU1

[PC Only] Did you remove all your community mods/add-ons? If yes, are you still experiencing the issue?
At this point didn’t tested yet using only the default models

FREQUENCY OF ISSUE

a matter of seconds to minutes once traffic should appear.

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

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue:
Connect to vatsim in busy airport, either on air / ground (observer mode)

YOUR SETTINGS

If the issue still occurs with no mods and add-ons, please continue to report your issue. If not, please move this post to the User Support Hub.

Thanks, yep got it. That’s mainly related to the injector. But still, it’s MSFS/Asobo
responsibility to keep backwards compatibility with the models and clearly something got broken now.

FSLTL’s models are also causing a CTD when used with the default Live Traffic feature, and when injected with BATC.

AIG’s models also cause a CTD with used with default Live Traffic or BATC

The default AI models are not crashing the sim.

Can confirm, tested AiG with AiG Injector, FSLTL with their injector and both with default injector.

Description of the issue:

Despite the updates of the inbuild AI planes. It causes the AI traffic from AIG and FSLTL causes to not working anymore. As soon as enabling the traffic is immediately causes a CTD. I wondering why Asobo/MS does’t give the AIG and FSLTL developers access to the systems which are responsible for AI traffic. Why close off / encrypt these systems?

Did you experience this issue before you joined the Beta?
First yes, but after fixes by the developers not. With the newly SU2 beta it even got worse.

If applicable, which aircraft is experiencing this issue:
not applicable

[PC Only] Did you remove all your community mods/add-ons? If yes, are you still experiencing the issue?
Yes accept for the AI traffic by the aforementioned developers.

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)? Immediately after activating the injectors.

REPRODUCTION STEPS

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

  1. Install AIG OCM, the manager for downloading flightplans, models and liveries
  2. Open the FSLTL latest injector 1.6.8 after installing their models and liveries.
  3. Load in a flight, start the injector wait a second …CTD

As mentioned, our release notes and changes to the FSLTL injector are in no way related to the CTD issues here. We assume some level of regression -or- some new requirement for models/liveries in SU2 that would explain why their (Asobo’s) own models/liveries don’t cause CTD as often as those from AIG & FSLTL. But we haven’t received any communication about what that new requirement might be.
Almost similar to MSFS2020 when in a few updates the old .mdl models caused CTDs.
Just have to wait and see if a future SU2 updates fixes this… or Asobo releases new requirements for models/liveries in MSFS2024.

I turned off the default live traffic and the sim crashed after about 10 minutes or so.

Same issue being experienced here. Also, just connecting to vpilot causes and instant game hang… eventually vpilot actually disconnected itself saying it detect the game being hung, and as soon as it disconnected the game started working again. Tried flying without vpilot and got a CTD 10 minutes later. I was however flying the A2A Comanche so issues related to that can’t be ruled out. I have not yet updated the FSLTL injector. I am going back to SU1 for now.

Already notified the FSLTL team about this issue and a potential fix.

Currently they are waiting for Asobo to make a statement, if the change required to fix will be mandatory or if its a bug that Asobo will fix.

For anyone interested, this is the explanation about the possible fix from Fenix Discord:

“MIPs fuc- oh, a public summary? Ok. mipmaps are now required for effect textures (e.g. those used by lights). This is a problem with forced MIP-streaming and it means the game engine never loads the full resolution effect texture, leading to 1/16th resolution shadow/light maps. Nothing we have found as a workaround except adding mipmaps for now. It will look pretty awful but it’ll function.”

sounds like that might be a different issue then.

I doubt it. I removed the base FSLTL folder. Then I went to the same airport, KDCA, turned on the default live traffic, watched the traffic using the drone like I always do if I’m testing, and had no CTD.

I might try later with nothing in my community folder except FSLTL and a different airport that isn’t a third party airport.

Thanks for the update. I know this must be as frustrating for you, probably more so, than it is for us.

Just want to confirm that the FSLTL models are still causing crashes on VATSIM. Is that correct?

Multiple sources of MSFS2020-developed models will cause sim crashes in MSFSF2024 SU2 (inital beta build). It is not Vatsim specific and is not FSLTL specific.

Per Asobo, this issue will be fixed in a future SU2 beta update, but there’s no ETA on when that will be.

If I remove all the effects connected to the AIG models it still crashes, so I’m not sure if that’s the issue here

But we’ll see when the fix gets pushed out.

Working for me so far with FSLTL and the FSLTL injector.
