Beyond ATC Traffic injection performance issues

If you had the same number of AI aircraft around you the difference would be within a couple of FPS. Sometimes better using AIG and sometimes better using FSLTL. The issue is that people think FSLTL is lighter on performance only because it injects a lot less aircraft.

Isn't that also due to the fact that FSTL does not have multiple registration liveries per airline?

In AIG you get a livery for each and every aircraft an airline has.

No. AIG does have many special liveries and variants painted but not one for each registration.

 Some examples. JetBlue, AIG has 42 different livery variants, FSLTL has 11. Ryanair, AIG has 20 variants as well as the Max200's, FSLTL has 2 and no Max200's. Frontier, AIG has 127 variants and FSLTL has 13. Alaska, AIG has 33, FSLTL has 4 and no Maxes. Southwest, AIG has 36 and FSLTL has 3 and no Maxes.

I'd want to add density as well as numbers.  BATC spaces traffic so far apart often at the levels I use for performance considerations that when I use FSLTL alone, its injector with BATC's traffic turned off, I get much more traffic closer to me, and yet much better performance.  It's no wonder really since BATC is managing all other traffic.  I'll stick with FSLTL w/ BATC ATC only for now it's a compromise but a very decent one in terms of user experience.

A solution batc could do is add a slider filter for traffic distance injection like fslt injector where only inject traffic a custom distance and same with ground aircrafts  where multiple airports are very close.

Even so, I get more stutters in FSHUD with FSLTL or AIG than with BATC with the same 3d models...

never delivered?? - you're in a beta program for crying out loud.  Wait till it is actually offered out of beta.

Crying out loud or quiet it doesn’t matter the developers themselves do not take suggestions nor reports from their customers it literally took them two weeks of gaslighting and denying to acknowledge memory leak problem..

besides, it sucks in every way an app that doesn’t work from the get-go and require this so much headache is an app to be put in the bin

disregard

It's a bit of an ambience charade for sure.  But it works in that regard very well by virtue of low traffic density I always experience ample separation--never in conflict with other aircraft.  But of course I'm doing some of my own traffic control for example by holding when another aircraft is taxiing on my taxi route, but that's not new for me because both BATC and default 2020 ATC do a poor job of controlling ground traffic in my experience.   It's really for ambience and of course its ATC is still good for routing me--much better than default.  it just doesn't need to think about how to do that relative to other traffic.  I'll keep checking back with BATC's traffic and when flying lightweight aircraft like the Longitude or TBM I can certainly still use BATC's traffic.  But TBH I've always marveled at how FSLTL could inject and control (or broker control) and have perfectly smooth animation always and I miss that with BATC.   I just saw a parade of three airliners heading to the threshold at KPDX and all of them taxiing w/o a hint of a stutter.  That is rare, even with one, with BATC for me.

That's because FSLTL uses the native sim method of injecting traffic whereas BATC injects it as a Simobject. I get that you're having issues on your side but I don't experience any stutters with BATC and I have all traffic sliders in BATC at 7 and get a solid 60 FPS (with FG on) in MSFS24 at EGLL. There's so much traffic it even causes the odd go-around and it's as smooth as it gets.

Out of curiosity, do you use V-sync?

Yeah a bit weird to have ATC yet nothing separating you from traffic, the whole point of ATC.  Each to their own.

I experience very good frames since version 2 of FSHud, and it routes me precisely and separates me all the time.  No idea why its not a more popular program. 

I decided to try turning off traffic in BATC, yesterday, to see the effect on performance, switching to the FSLTL injector.  I seem to get about a 20 % FPS boost without BATC traffic. I missed the ATC chatter, so I reinstalled FS ATC chatter, which I haven't used in a long time. The latest version of FS ATC chatter works great. Now I am flying around Australia, and the chatter is from that area, and the switching when BATC switches from gnd to tower to center etc, also switches the chatter automatically. Works great.... I never had an issue with FSLTL injector causing problems, so I expect that won't be an issue now.

Nope, don't use V-sync.  I can tell you I have exquisite image quality and it's rare to see stutters anywhere in any plane.  It puzzles me as well why I don't see the same smooth traffic others report.   Right now I'm using BATC's injector, with only L3 traffic sliders, and will be arriving into KSFO in a bit.  I will do a very short video at low resolution to show what happens at arrival when I turn BATC's traffic off, after landing.  There have been several updates to BATC since I last did this test where I had a 35% improvement in frame rate at the more demanding arrival settings using FSLTL models.  I did this same test yesterday, however used FSLTL's injector and the FPS gain was about 10-12%.  Hopefully it's improved from that last time.

Kudos for trying something instead of dismissing it out of hand.

I experience very good frames since version 2 of FSHud, and it routes me precisely and separates me all the time.  No idea why its not a more popular program. 

I almost bought FSHud after failing to get rid of stuttering traffic in BATC but really like the simple BATC interface and with so many others apparently not experiencing this I'm going to stay with it a while longer.  If this continues I'd best give FSHud a shot.  Does it use FSLTL models?
