FSLTL Settings Guide | Microsoft Flight Simulator

[@WhakaMole]

Hey Q8Pilot - thanks for showing our product and your suggested configuration. As the dev of the FSLTL injector I'd like to just point out a couple of things that were not quite right. The 'Max Radius to inject Ground Aircraft' - this only affects the IFR injected traffic distance not the additional aircraft distance. This will mean with 150km set in busy airspace you will be injecting IFR traffic at all the surrounding airports. So with your KLAX example that could see a significant number of extra aircraft on the ground at other airports like KBUR, KSNA etc. In addition the 'Absolute Max Airline Parked' setting only impacts the static parked aircraft, not the IFR aircraft - so won't limit those aircraft on the ground that are true IFR aircraft. I suspect that is why you see a bigger drop at KLAX. With respect to Additional Parked Airline aircraft, a setting of 10 is equal to 50% (as opposed to 100% as noted in the video) of the overall suitable parking spaces with radius greater than 10m. The in air radius definitely won't have a direct impact on performance, other than potentially reducing the number of aircraft in the air if airspace isn't that busy. In KLAX region 100km or 150km air radius will often have the same performance impact as you will still hit your overall IFR limit if its prime flying time. (You would be able to see that from the IFR counter displayed in the console window) Personally I fly with 150km air and 30km ground radius - which for me gives the better experience. Final note is with respect to VFR traffic - VFR in FSLTL is an aircraft that has not origin or destination in FR24, or just one of them - i.e. we don't know the start and end point. In KLAX region you will see plenty of these flying if you monitor them on little nav map. We would definitely advise anyone to also review the user guide so they can read what each setting does in detail... www.fslivetrafficliveries.com/user-guide/

Thank you for this amazing software, this is top of the line, and there is no better one. But it would be great if is was less heavy

[@aaviation]

I agree somewhat, however, if you use this instead of the in-game "live air traffic" you should get much better FPS. @@guillelite7385

[@neelprabhu]

I'm not sure I agree that the performance you were experiencing was "good". In my mind, good performance in a simulator means smooth performance which equates to consistent frametimes across all loading scenarios (FL 350 or on the ground at a busy airport). Dropping from 64 fps to 44 fps during takeoff roll necessitates changes in frametimes which the eye experiences as stutters. Instead a better approach is to aim for a consistent frametime through frame rate limitation. Just my 2 cents.

The issue isn’t the CPU or GPU… it is the standard cache settings. Nvidia makes the cache 1 gig standard. I bumped min to 100 gig and deleted all current cache files… fixed stutter in all my VR games including MSFS.

Hi Q8Pilot - a great video again thanks. Not sure why FSLTL has become such an FPS killer very recently. I have an i9 32GB Ram and RTX 2080 Super. At the freeware EGKK using FS Traffic with a setting of 20 flights per hour (so fairly full) I get an average FPS of 41. When I switch to FSLTL using a similar traffic load and using FS Traffic models as priority my FPS drops down to about 25 and stutters. I note that with FS Traffic I get a good balance between GPU and CPU however now with FSLTL I get constant red and solid limited by mainthread. Any ideas if something has changed with FSLTL?

[@lar5ma]

By the way, was frame generation enabled here? It may be relevant for performance

[@Q8Pilot]

Frame generation is on, but this has no relevance here. The relevance is how much FSLTL taxes your FPS and what settings will reduce the resource consumption.

I'm lucky to get 35 to 40 frames per second and with FS LTL at the larger airports I will get some stuttering and a definite big-hitting framerate. But I do love fsltl. Thanks for explaining the settings a little bit more detailed. I will play around with them.

Does FSLTL traffic have a touchdown effect when landing?

[@thatguy7085]

Lag and stutter… if you don’t get it when you begin… but it shows up later in your flight, or when landing… Delete your rolling cache files in the general options, data... Frame rates go down because there is a bottle neck holding up the processor. Almost always… cache files. Also check your video card. They are saved in there. Change settings in the video card card settings for larger cache file to prevent overflow. Standard is 1 gig. Make it at least 10 gig. Mine is 100. No more stutters at maximum settings.if frame rates are good when you start up the sim… should be good the entire flight.

[@speedbird8326]

Do you mean delete rolling cache and turn it off or delete rolling cache and allow it to re-generate ? If the latter, how much rolling cache size do you set ?

[@GarrisIiari]

This advice has always confused me, as I considered timing cache to be a theoretical speed enhancer. If it can bottleneck, then what's the point at all? Just saving data? Why not turn it off then?

Hi, Why does your GPU doesn't go full 100% load for max frames. I have the same problem on busy airports and scenery my GPU will backtrottling. Less processingpower of the GPU for more scenery will result in massive framedrops, just at the paces you need it the most. My CPU only uses around 40% Temps, Power internet speed and 32GB Ram and all on SSD wouldn't been a problem.

[@ati4280]

That's because your CPU does not have enough single thread performance. CPU itself also have a FPS counter, the optimal situation is CPU fps matches GPU fps. If one of these has less power, the other one will throttle down just as you said. Even though your CPU utilization shows only 40%, it is bottlenecked. The usage only tell you the capacity of CPU power in use, not its actual processing speed.

[@LennardA320]

@@ati4280 in my case the CPU is more powerfull than the GPU. In the way off during FL2020 He uses like 30% of the CPU and why wouldn't he use then 100% op GPU. There is enough power left for the CPU to ramp up.

[@ati4280]

@@LennardA320 There're many videos explain what is a CPU bottleneck. You may watch videos from Gamer's nexus or hardware unboxed.

[@LennardA320]

@ati4280 I am not that technically about how everything works. However my CPU With 32GB Ram has so much overcapacity that it only uses about 30% of the totall capacity of the chip. So when I play flightsimulator. Why if your GPU can go to 100%. Why does it happen called "GPU Throttling" that when you go to land and there is more to render that instead the GPU still uses about 100% what it normally does to give as much frames as possible. So if you are cruising the gpu us standard always about 90-100% But when de scenery gets heavy. Even with Rolling Cache and here in NL Glassfiber internet. Why if the CPU isn't doing that much that still the GPU is Throttling back to maybe 50%. So due to heavy scenery you always lose frames and especially if your card is working half you losing almost your whole experience. So far I can understand is your CPU has many Cores & Threads. And is FL2020 not optimalized to use as much cores as it can. I have 10 Cores. But do you mean it can maybe use only 6 of them so those are at 100% the rest only few per cent background so your gaming Threads are fully utilized however because the other Cores don't help the game you see that the complete utilization is less than 100 so you see maybe 40%. If this is the case. Why don't FL2020 don't use more Cores because there are far more expensive CPU's that have a lot more Cores and Threads. Am I right what I am writing here?

[@ati4280]

@@LennardA320 I totally understand your confusion, and I was confused years before. The bottleneck is rather complicated, cannot be explain clearly within one or two words. The CPU is used for scenery pre-rendering. It prepares all necessary stuffs before GPU kicks in. So, when heavy scenery in coming, or you start at large airport like Helsinki in your country, this makes CPU pretty hard to prepare all sceneries to match up the speed your GPU has. Speaking of speed, let's make it simple. You said you have 10 cores, I don't know what exactly model it is. I have a 6 core AMD CPU instead. More cores is something like more horsepower, but it doesn't mean you can go faster. E.g. M1A2 tank has more than 1000hp, but it cannot running at a speed of 300kph like a 400hp Porsche. You have more cores, but if your CPU is several years old and with a lower clock speed, that the possible reason you only see 40% usage. The reason for over 90% GPU loading while cruising is that when your altitude is high, there's less scenery processing demands unless you have high TLOD setting over like 200 TLOD. Yes, MSFS is not fully optimized for multi core, but it does use as many cores as possible to process sceneries and other stuffs. Keep this in mind, your FPS only bundle with the slowest hardware.
