how many lines of code have you written in your life?

how many different pc configurations have you serviced/managed in a department to make such a useless comment?

why then is it so difficult for Asobo to sometimes reproduce errors reported by users? I never heard them  ever say "our systems are stable. You suggest that yours is not. Again, perhaps it’s  you?"

AMD 7800X3D, Windows 11, Gigabyte X670 AORUS Elite AX Motherboard, 64GB DDR5 G.SKILL Trident Z5 NEO RGB (AMD Expo), RTX 4090,  Samsung 980 PRO M.2 NVMe SSD 2 TB PCIe 4.0, Samsung 980 PRO M.2 NVMe SSD 1 TB PCIe 4.0, 4K resolution 50" TV @60Hz, VR: Pimax Crystal Light + HP Reverb G2 @ 90 Hz, Honeycomb Bravo Throttle Quadrant, be quiet 1000W PSU, Noctua NH-U12S chromax.black air cooler.

60-130 fps. no CPU overclocking.

very nice.

Well since you asked and since you presumed I might not have a response…

For over 30 years of my former professional career (retired) I managed IT Systems and IT Staff and over 20 of those years were spent in Global Enterprise Server And Desktop Functions so yes…I too know a thing or two. 

My experience is yes, the platform software can be at fault  in major fails such as the CTD being discussed, but more often than not they come not from one specific bug or trigger but a combination of triggers or events that come from both sides, client and platform. 

So yes, my machine (and many others) can run in the same environment as yours and never have a CTD, while you (and many others) experience CTDs every session.

So I say again, my machine runs stable. Perhaps its you?

mine runs stable too, but I see people having different configurations, different drivers, add-ons, peripherals or hardware that can cause problems you and I don't have. if it is not working on someone else's machine doesn't automatically mean it's his fault. therefore your comment doesn't offer any help to him whatsoever.

Does it?, are you sure this flow visualisation isnt just for use during development?

Well since your system is stable and with your wealth of experience, could you please tell myself and the others in the below forum the solution for the drop in frames over several hours of flight please.

 

I've just had another flight shy of 4 hours that crashed on final approach, 2 out of 3.

 

It would be much appreciated.

Gliders: https://youtu.be/_AAiraI837U?t=2573 "... once in the air to stay in the air you need to find places where the air goes up, experienced glider pilots will know where to find updrafts, but we added a system to see them in the environment ...", which at the very least confirms that atmospheric airflow visualizations are coming in SU11. 

Hopefully they'll go into more details in the upcoming Q&As and feature discovery videos before SU11.

I believe the 20 km cube around the aircraft is probably going to be used to "normalize" / "integrate"  / "increase the granularity of" the various sources of energy that concur to generate rising and/or sinking air currents as well as intensity and shifts in wind direction affecting the aircraft at it's present spot or further ahead. Maybe in the future they can even add wake effects like those simulated in DCS World or XP11 ( and I believe refined for XP12 ).

Looks like an interesting approach !

The Soaring Weather is a feature I am really looking fwd into 🙂

Ground physics would be great to see updated to their new ground physics model. Yesterday they were playing quite a role in my takeoff and later landing at LPMN with a 10 gusting 15 knot x-wind... Following the glider tug, which is actually pretty much like formation flying, is yet another feature of soaring operations when using such a type of initial rise from the surface, that I would love to see more plausibly modelled than in MFS, XP, and even Condorsoaring. IMO Silentwings is stll the soaring simulator that so far more closely created the experience of glider tugging - speaking of which it necessarily comes to my mind that representing the wake from the tug, and even being able to train "boxing the wake" would nice to have too 🙂

Ya it's going to be interesting to see how exactly they employ CFD in this 20km cocoon and you might be on to something in your guess. When Seb was talking about vortexes I presumed he meant the vortex-ring kind of thermals (i.e. rising air in middle and descending air on sides, https://www.flightliteracy.com/thermal-soaring-weather/), or maybe he meant vortexes as in https://en.wikipedia.org/wiki/Vortex , i.e. those generated by wing tips causing wake turbulence. Of course both could be simulated too. I remember they added some wake turbulence effects in the core sim to coincide with the Reno add-on or SU7, but that was likely very localized and not a full set of wake effects.

I too am looking forward to this, and also beyond gliders to see how it affects all aircrafts and general aerodynamics (the more I think about this atmospheric airflow CFD will likely not be a per-aircraft thing like the current CFD stuff is, but globally applicable to all aircrafts?.. if it doesn't come always enabled by default then it'll likely be a global setting which we could turn on or off or further customize in-sim)

Im not convinced realtime CFD of a resolution needed and encompassing a whole airframe for accurate flight dynamics is within the scope of this sim and the average PC.
On a larger scale and applied to airflow over a less complex shape like a smoothed out surface - averaged mountain ridge Yea probably do-able in realtime on our machines right now., so quite accurate winds over mountain ranges would benefit

Yup certainly not real-time and full solution of Navier-Stokes equations. At least not on current PC hardware. They mention they use a *custom* version of these equations (https://docs.flightsimulator.com/flighting/html/Developer_Mode/Aircraft_Editor/Debug/Debug_Aircraft_CFD.htm). And the discretization in the solving/calculating can be increased by setting certain parameters, but of course due to the O(n^3) complexity performance will quickly deteriorate... but who knows, with CPUs advancing as much as they are the processing can be brought closer to real-time CFD sooner than we think.

It’s a mistype…

He meant to type, “CTD”!
