Hello all, I was doing some performance testing yesterday in the Fenix along with PSXT/AIG.  In doing so, I noticed that with PSXT/AIG on at a heavy airport such as ORD or LAX, I was getting 20 FPS.  When I turned it off, I bumped up to 35 FPS.  Keep in mind, i am not a FPS chaser by an stretch and have been pretty smooth for the most part with only some stutters on short final as mentioned in other posts.  My question is, for those of you with similar specs as mine that use the Fenix or PMDG, do you use FSLTL or PSXT and what are your settings / experience between them?  Does FSLTL perform any better than PSXT?  I'd hate to fly without traffic so I wanted to see if anyone had tips on smoothing out the sim when flying with traffic.  Thanks!

I can't help but feel you could be getting better performance than you are with that rig although I have no idea what sort of graphics settings you are running. I'm basing that on your FPS without traffic running. 35 seems very low to me with that hardware. With no traffic running I can get 55-60 at inibuilds Heathrow with pretty high graphics settings. Many things on ultra and nothing below high. I even just moved my TLOD slider up from 100-150 and still saw similar results there.

Anyway, my rig is not terribly disimilar to yours and I run FSLTL at the moment. Although my settings in there seem very modest  I actually get a reasonable amount of movement around me and plenty of aircraft at my departure and arrival airports.

My FSLTL settings are:

Max Active IFR Aircraft: 14. Sounds low but honestly it does create enough movement to be believable most of the time and it doesn't hammer my CPU too much.

Additional Parked Aircraft: 3. Creates enough static airport so the airport doesn't look dead. However, in the very large hubs like Heathrow it can look a little empty but it's a compromise I'm willing to make for performance.

Absolute Parked Aircraft Max per Airport: I mostly keep this at 30 for the airports I fly into but like I said Heathrow seems a littel sparse with this number. Sometimes I will bump it up at such places to 40 but performance is most importanct to me so I don't push things and lose it.

Max Radius to Inject Aircraft in Air: I have messed about with this and honestly, I couldn't tell the difference as a virtual pilot in terms of what I was seeing in the sim so in the interests of performance I shut this down to 50.

Max Radius to Inject Aircraft on Ground: I actually can't remember what this is but my bet is the same or even smaller that 50

Blocked Aircraft Removal Time: Kept this as default

FlightPlannerDB API: I do have a key for this and use it

Disable showing Blank liveries: I disable these. I don't want to see blank planes.

Disable showing Generic Models: I have allowed this to stay as default.

I know many people will look at those settings and think.....NOT ENOUGH TRAFFIC! but honestly, it really is most of the time. Only if you are flying in and out of mega hubs does it look wrong. I was at Palermo the other night and there were plenty of aircraft on the ground and plenty of comings and goings. It actually felt unrealistically too much movement for that airport but may of just been the time of day I suppose.

Main point is it allows me to keep my FPS up and it rarely drops below 48 with the PMDG 737 anywhere and in the air I'm mostly up at 55.

The hardest place for it that I have tried is iniBuilds Heathrow and I have seen drops to 44 there.

Hope you find that useful somehow.

There is an option for PSXT where you may decrease AI population down to 10mi while you're on the ground. It gets me about 7-10 FPS in EGLL and KLAX

Maybe PSXT/AIG is more taxing. I'll have to compare it to FSLTL to see. 

My settings are the following:

  Full Screen / 3440x1440 (i am getting a bigger display today so that could change)

TAA

Render 110 

AMD Fidelityx - 170

Vsync ON / Nvidia Low Latency - on + boost

100% refresh rate

DX12

LOD 200

Buildings, clouds, texture res, texture synthesis, light shafts  -  Ultra

Trees / Grass, waves, contact shadows, ambient occlusion, depth of field - high

Anisotropic 16x / supersample 6x6

shadow maps - 2048

terrain shadow - 1024

cubemap - 256

bloom, motion blur - off

raymarched, glass refresh - medium

It was your FPS without traffic running that made me wonder but I can see two things in there that explains why yours are lower than mine. You are using a wider monitor than mine as mine is only 2560x1440 and you are using a 200 LOD setting by the look of it. That's high for flying tubeliners in my opinion but to each their own. I have been running 100 with heavy tin for performance but since the update yesterday I upped it to 150 and so far have not seen anywhere near as bad a hit as I was getting before yesterdays update and I simply have no clue why that is. I found it odd. Although, I admit, I have not looked at the changelog. I don't believe there was anything in there that would explain this, though. I will keep using it for now unless I see performance is suffering. The only thing that bothers me about a lower LOD when flying airliners is that the street lights spawn in a little close to the aircraft and this becomes more and more obvious the higher you climb. Although MSFS does a pretty good job of blending them it is still kind of obvious so to have them pop in a little further would help the ilusion at night. Dynamic LOD really would be nice to have.

I'll try lowering the LOD.  Thanks!

For a heavy airport as ORD and LAX, you better lower your graphics settings. I have a 5 years old PC with a i5-8600K 3.6GHz, 16Gb Ram and a GTX 1070Ti graphics card. A very moderate rig so to speak.

However, at INIBUILDS Heathrow, with PSXT + AIG and PMDG B738, with 60 parked static aircraft and 40 live aircraft (lateral range 20 nm) I still get 25-35 fps depending on where you look. Although the fps are not high it stil looks smooth. You can get higher fps by ticking Auto range in the PSXT GUI.  At smaller airports like Ibiza my fps are in the fourties.  

So lower your MSFS graphics settings if your fps are too low.

Well, only if you are looking for more performance. If you are happy with a lower frame rate then you're happy. Some would prefer to see the lights at night appear further away than have a higher frame rate whilst others like me prefer to have the performance. Like I said, to each their own. No harm in trying to lower TLOD and Objects to 100 and see how you like it though. I don't suppose you will know what you prefer until you do. Perhaps you already have.

Of course, I like everyone else I still wants a super CPU that hasn't been invented yet that lets me set eveything up to 11 with a million FPS and 600 AI aircraft 😆

Any day now. I have been saying that for 30 years.

with the Fenix? that makes a difference.

I had traffic injection set to 50 so I will scale that back for sure.  Where do I set parked static and live where you say 40 and 60?  Does the sim need to be running for that?

I like your FSLTL settings, but I find the performance with the 737 is rather good. How many FPS do you get at EGLL with either Fenix or the A310 (which are heavier)?

You can find all that in the Manual, you know ...:

The parking percentage determines how many static+live aircraft you will see parked. You can set that in the GUI if PSXT runs, or in the airport file directly (PSXT not running).

The lateral range, that is the radius of the circle around your user aircraft determines how many live aircraft will get spawned in your Sim. The lower the less. Range is 5  to 100 nm. You can set it in the GUI (PSXT needs to run), or in the parameters.xml file directly, if PSXT is not running.
