Quick flight KLGA-lower Manhattan-KLGA at 1500ft. 

What's the deal with PG fully loading only when flying directly above? Has it been like this for a while / forever?? I haven't been paying too much attention to PG cities for a while. 

Btw I'm getting around 15-16gb used VRAM over Manhattan. Only about 6-7gb used RAM.

Absolutely love the visuals (and limited functions) of the new G3X.

But I'm not going to lie, I'm gutted that autopilot FMA annunciations are not included (yet).  I don't mean the G3X's integrated AP, just the mode annunciations, which don't appear on the PFD, even when the autopilot is activated in the VL-3. 

But.... appreciate it's a first beta and I can't wait to see how this new G3X develops!

Answering myself here: I had the dynamic LOD mod running, which I've set to TLOD 100 below 1500ft.

The Captn of CapFrameX captures 😀 those are remarkably constant frame times and explains why it is now so smooth, near ideal. I have extracted a 3 minutes section from your benchmark to illustrate this even further: it's the frame times, not the frame rates.

Indeed! The frame time variability is ridiculously low!

For those wondering, I presume the new ground handling parameters in the Flightmodel.cfg are :-

ground_new_contact_model_rolling_stickyness = 0.5; default = 1.0
ground_new_contact_model_up_to_speed_lateral = 1000.0 ; default = 0.1
ground_new_contact_model_up_to_speed_longitudinal = 1000.0 ; default = 1.0
ground_new_contact_model_gear_flex = 0.005 ; default = 0.0
ground_new_contact_model_gear_flex_damping = 5 ; default = 0.0
enable_high_accuracy_integration = 1; default = 0

About to try experimentally transplanting these to another aircraft, to see the result. 😎

Ground Contact Resolution Improvements

• More accurate ground contact model.
• Optional soft ground collision model for tires / flexible gears.
• Enabled new soft gears on C172 and Cabri.
• New high accuracy physics system to enable vibrations and micro movements.

 

I haven’t tried the beta yet, and Matt was pretty clear that there is no change to aircraft like the PMDG737, however, I read this section above as a more accurate ground contact model was implemented and there is an additional soft ground collision model for tires that can be implemented.

It seems like bullet point 1 is what people are seeing in the 737 and other aircraft and bullet point 2 is a level up from that. 
 

At least that’s how it reads to me.

I just tried a 360 on a runway at 10 knots and it was possible where that would be a complete struggle prior to beta.

I take it you applied differential braking?

They definitely are included and working. I would try with an empty community folder, it's possible something is overwriting some wiring.

hm, Matt Nischan only mentioned the aircraft.cfg ??? only my C172-G1000 flight_model.cfg is from 14/02/2024, the aircraft.cfg is still from 11/10/2023, the analog C172 no new flightmodel still from 2023.

And I was thinking WT had actually simulated real-world GPS reception issues.

Well, we do, and that was part of the problem. The satellite simulation, which uses orbital mechanics to place satellites in real positions in space, was slowly forgetting about satellites over very very long time frames. So eventually you would not have enough satellites to get a position, and thus the LOI message.

Now the system is no longer forgetting about satellites, and the position solution is resolved just fine. 🙂

By aircraft configuration, I was referring to the total set of CFG files that make up the aircraft. I'm not sure which one these are in, specifically.

thanks for this great find. I have now applied this to the [FLIGHT_TUNING] section of the analog C172SP flight_model.cfg, should behave identical to the new C172G1000 flight model. 😀

"About to try experimentally transplanting these to another aircraft, to see the result. 😎"

and me. we will probably hear back soon from many "ground_new_contact_model" tweakers.

4k, 12900ks, 4090: seeing better performance but turning on realtime online traffic (unsurprisingly) still hammers the thing nastily: down from typical 50fps to high 20s/ low 30s at EGLL (before frame generation). 

Often thought that traffic might be a candidate for its own thread(s). Any word on whether this is one of the multi-threading improvements promised for MSFS 2024?

Where did you find this? My flightmodel.cfg (C:\MSFS\Official\OneStore\asobo-aircraft-c172sp-classic\SimObjects\Airplanes\Asobo_C172sp_classic) was last updated 9th Feb. 

EDIT: found the updated section here: \OneStore\asobo-aircraft-c172sp-as1000\SimObjects\Airplanes\Asobo_C172sp_AS1000
