Hi does anyone know if reducing texture size reduces CPU load, or just VRAM load? I fly in VR with a 3090 and struggle with main thread, but never use more than 50% VRAM. Thanks!

I’m still struggling to understand this:
“…number is scale linked to percentage of parking spots…”
Could you elaborate for me on the relationship there between those values? If I set the Historic to 1, for example, at an airport with 100 parking spaces, what does that translate to? How do I understand what the 1-10 is going to really do?
Sorry to be so obtuse…

Please wait for the developer to confirm this but I find this relationship between the 1 to 10 values entered in the console and these values stored in the config file
Additional Airline Parked Aircraft: Airport parking spots used for static aircraft. Default is 2 = .1, 3 = .15, 7= .35, 10 = .5
Therefore I interpret this as enter:
2 to use 10% of the total airport parking spaces
3 to use 15% of the total airport parking spaces
7 to use 35% of the total airport parking spaces
10 to use 50% of the total airport parking spaces
i.e. use (integer entered time 5%) of the total airport parking spaces

The above is correct with an additional detail. For airline additional parking the total parking spots value is the sum of parking of radius greater than 10m, for GA it’s for less than / equal 10m.
These parking values are taken directly from the sim via the facilities api so are accurate for whatever scenery you have installed.

Please someone can confirm which is the last stable version of FSLTL Base Models? Is 1.2.1?
Another question, do I need to install also the Injector to have the Base Models if I only want to use FSLTL in VATSIM to see airplanes of others? No, correct?
For me Injector it not relevant as real traffic for me it’s not relevant as well.
Thanks in advance by any response.
Flying in a group or on same server with a friend we noticed, and we expected somehitng like that to be fair, that FSLTL aicraft injected do not appear synchronized between group players, I mean me and my friend were following a liner with a 104 at FL370, but while aicraft we were following was at same FL for both of us, it appeared laterrally offset of about half a mile between me and him, while we flew tip to tip. Same height, seme pos in time, but laterally offset.
Question for dev’s:
Will it be a way to make them quite synchornized in the future or, and I could understand, not so easy and probable?
Thank you
Realistically never going to happen with current sdk. Ultimately the solution for that will only ever come from Asobo as we only provide the flightplan data for the AI aircraft - the sim flies them.

Thanks for the answer.
Yes, I think soo too.
It’s amazing what traffic can do to FPS (specifically Frames speaking, not stutters).
Not to make people stop using this great tool, or any other traffic tool for that matter, but:
Before you give up on a busy handcrafted US airport and start brainstorming how are you going to have a smooth visit to KMCO for example to visit Walt Disney Land: Turn off traffic and try again lmao.

I think the problem is many people are using these tools and injecting ludicrous levels of traffic.
As you say, it inevitably has a detrimental effect on fps, so dialling it down to realistic levels doesn’t hurt at all.
For example, there is no need whatsoever to inject airborne IFR traffic close to 200km away from the player. Similarly there is no need to inject ground traffic anymore then 10km from the player.

Yes, any moving object is FPS killer in the sim though. Then I upgraded to RTX 4090 along with 7950x3D, now I can even get 70-80 FPS in JFK with ultra settings. I used to have RTX 3080 with i7-10700K and still was happy with my performance because I was adjusting my traffic according to my system. I think FSLTL is just perfect in many sense, and in terms of performance, one could adjust it accordingly I believe.
FSLTL is a very versatile and well thought of tool. I agree, no need to inject traffic very far.
Tip: Make fps headroom in your sim for AI.
Whatever the min fps is at a dense airport you are able to tolerate (30fps for me), target 10 to 15fps above that figure and dial your graphics settings back until you achieve that figure of fps. Then add in ai traffic.
So say sat at Ini’s EGLL (which can be tweaked for perf too), and you are happy with say 30fps absolute minimum. Target 40-45fps, and tweak graphics options and other traffic sliders down to get to 40-45fps. Then add in AI traffic at reasonable levels until you are sitting at your lowest tolerable 30fps level, then back off a bit. You may want to do this in rain too as it’s worst case graphically.
I don’t run with high AI density or huge amounts of static aircraft, and I always think my airports look busy enough. The sim still looks great graphically too.
Having used this technique and been happy with the outcome, I don’t even look at my fps any more. 5950+3090@4k.

35-40fps with frame generation 
I’m using DLSS2, I’m just envious.

Right on point, you nailed it. FSLTL actually exactly shaves off around 10-12 FPS with passive yet moderate enjoyable settings.

It’s just crazy. Imagine landing to Heathrow with 60 FPS on 4K, all ULTRA while all the AIs are taxiing, taking-off,landing. I watched a lot of videos on youtube before I bought them but now I see it clearly

Yes, and if you don’t plan for ai then you just get frustrated arriving at dense airports while your fps tanks. There’s a lesson there.
This sim is all about tradeoffs, and we are nearly all cpu limited and ai traffic is a cpu loader, so you have to find cpu cycles somewhere to accommodate it.

What settings do you use for FSLTL?
I do the opposite and rather than make room I usually do a stress test with AI already active at a dense, urban airport, and adjust settings from there.
For me, that means dialing up INI’s KJFK (which I think needs more optimization anyway, but that’s a different thread) with SamScene NYC loaded and running FSLTL as well and adjust settings (usually LOD) so that I’m seeing 30 FPS routinely there when landing or taking off with the heaviest airliner on frames (for me, the A310). If that works, then flying almost everywhere else in the world will be just fine as far as FPS…

I’ll need to check as its been a while since I looked. Which is how I know FSLTL is doing it’s job - when I don’t have to think about it. It’s just there running in the background like its part of the sim all the time and working. I have it auto starting from add on linker too so it launches every time I launch the sim.
I’ll post my FSLTL settings when I’m back on the PC later. It’s something like IFR 45->60, vfr 1, additional(static) 1, static capped at 10, ground radius 10km, air radius 150km, using fstraffic models as fill in, and using sid/stars, using FSDB flightplans, and I run FSLTL minus the terminal prompts every launch so using ini file parameters only. (This silent mode enabled from ini file.)
I’ll double check my current settings though and post later.
FSLTL to me is the ultimate fire and forget live ai traffic add on. It’s very easy to use when you set it up properly and crucially make room on your system (cpu load / fps wise) to accommodate it.
