FSUIPC 4.959 now has an AI Traffic Limiter somewhat like the Traffic Optimizer addon

Recommended Posts

The newest version which is compatible with P3d 3.4 Hotfix 2 is available for download. The Traffic Limiter is described as follows:

 

28. A Traffic Limiter option is now provided. This is enabled by parameters in the INI file, or more easily, by setting the desired limit in the edit box for this on the lower right corner of the Miscellaneous options tab. Traffic is limited by removing AI aircraft, from whatever source, as they are added, once the limit is reached. The aircraft being deleted is not necessarily the last one added. It will usually be the furthest one -- Traffic is only spawned within the “reality bubble” (about 80 nm radius) so that’s as far as it might get. The behaviour is modified by parameters in the INI file. There will be a new section, probably added at the end of the file, containing, by default:

 

[Traffic Limiter]
TrafficLimit=0
GroundPreference=50
AirportPreference=50
NearerPreference=50
The limit set to 0 switches the facility off.

See the FSUIPC installer ReadMe file for more details.

This works a bit differently, as it has more control over deletion of AI aircraft at varying distance within the user's reality bubble. I use these settings, which are in line with Pete Dowson's initial suggested values and the capabilities of my hardware:

 

[Traffic Limiter]
TrafficLimit=100
GroundPreference=70
AirportPreference=20
NearerPreference=70

That could work well.  I set my AI to around 10%...sometimes that means 3 airplanes...sometimes it means 30.  Now I can set a hard limit on the ground.

The three "Preference" settings are percentages (probabilities of deletion). See the release notes on version 4.959:

The other parameters determine how to decide which ones to delete when the limit is breached, These are:

 

GroundPreference: This is the % probability of nearby (0.5 to 20nm) ground traffic being deleted provided they do not already have clearance, or are shutting down after arrival in any case. Increasing this will give better frame rates and more free parking spaces at the local airports, but can of course ultimately limit the number of aircraft taking off. Decreasing it will delete fewer local ground aircraft, with none being deleted if this is set to 0. (I increase it to about 70 which still gives me enough local traffic and allows me to decrease the next parameter without spoiling the performance).

 
AirportPreference: The gives the % probability of aircraft destined for one of the six nearest airports (including the one you may be on) being deleted if it is a candidate (i.e. furthest, or as determined by the other parameters). The default of 50% makes this an even chance, other factors allowing. Increasing this will give less arrivals locally, decreasing it with give more. At 0 no local arrivals will be deleted unless there’s no other choice to keep to the limit. (I like seeing the arrivals so I take this down to about 20).
 
NearerPreference: This is the probability of deleting aircraft which are not necessarily the furthest away. With it set to anything above 0 the aircraft chosen for deletion might be anything from 20nm away. The idea of this is to give newly added aircraft in flight, spawned as usual at the far reaches of that “reality bubble”, a chance to follow their plans. Otherwise what is likely to happen, after the initial period where the aircraft are spawned all over the place (according to their schedules), almost every scheduled flight from anywhere outside that bubble would probably be deleted as soon as it was added. (I have this set to 70 as I like to see the greater variety of airlines and departure airports I get when newly spawned flights are not deleted so often).
 
The defaults are set at 50% so you can see the “average” results, and then increase or decrease them to meet your preferences. To allow experimentation here, this complete section of the INI file is re-read whenever you enter the FSUIPC Options screen and OK out (even if you don’t visit any tabs).
 
If they are all set to 0 (the original defaults in a pre-release) then the only criteria used when deciding which to delete is the distance – furthest only, every time.

I'm going to give it a try. I like the fact that I don't have to have another program running while P3D is running. Maybe there is no difference but at least it makes me feel better. :Big Grin:

What is the "correct" way to update FSUIPC - just run the installer to overwrite the current version?

Does this apply to the registered version only?

Excellent, thanks for the heads-up.

FSUICP just keeps on giving.

Is it payware feature? In downloads section I see only fsuipc compatible with hf1

Update: I answered myself, version available was recompiled on 19th and is in fact updated. Freeware version has no control over traffic, so it's "payware" feature.

While I have been content with the Air Traffic Manager, this is highly welcome. Potentially one more tool I could get rid of, if it works. I'll certainly give it a shot.

 

Will this work with UT2 (I think Air Traffic Manager doesn't)?

 

Kind regards, Michael

Pete tested it with MT6 and UT2 as he likes lots of Ai so the answer to your question is yes. :smile:

I'll go through the documents as soon as I get home but can these values be changed in real time? I know Air Traffic Manager allows you to do that to maintain desired performance on the fly. If FSUIPC allows that, then I'd be very happy to use it instead.

I believe so. You make the change and after clicking OK FSUIPC updates the Ai based on your new values.

Thanks for the quick response, Ray. Cheers and happy holidays!

Well I installed this , this morning and giving the AI controller a try. A feature of the Air Traffic manager that I like is it gives you an actual count that you can set of AI aircraft, and as soon as you have more than that, it deletes the AI. With the FSUIPC system you have to guess at percentages and what number of AI will result from the percentages. I just  activated Plan G which has a moving map and shows all the AI, and the FSUIPC seems to be working correctly since all AI are located close to where my aircraft is located. Will have to play with the percentages and watch FPS I guess to see if it is better than what I was using.

The first parameter is the maximum number of aircraft in the user's reality bubble. The other three control where aircraft are deleted spatially.

Sounds great. Always nice to recude the number og utilities needed to make the sim running.

 

I do hope though that LM make some major changes to their setup options, so one can do this from within P3D.

Thanks, seems to be working very well.

Interesting....I currently use the AI Traffic Optimzer program so I may have to try this!  Would be nice to eliminate another program that needs to be started up.  I assume this is "set it and forget It"?

Yes, once you have the settings you like, it starts up with the sim.

Yes, that's the point. The Traffic Optimizer was a "life saver" when first introduced as it really does add a feature that is sadly missing from FSX and P3d. But I'd rather rely on a veteran developer like Pete Dowson (who has an outstanding track record) to handle new features like precision AI optimization. And keep in mind that this is first attempt at such optimization by FSUIPC. It's likely to get a lot better as users interact with the developer. But not just yet. He's on holiday until after the new year.

 

Also, one can be pretty confident that FSUIPC is headed towards P3d 64 bit, if it isn't already being tested.

Lets hope so. Pete is still an FSX user... 

 

Even better, Lockheed Martin hired Pete and integrated all the FSUIPC features into Prepar3D. It's kind of silly that we still need all of these utilities to make the sim run as it should.

Do you set the traffic sliders in p3d like always or does this change things? Are you able to increase say airliners little more than in the past?
