I don’t understand why you opt for having 400TLOD and no frame gen?
I think you’re asking for trouble with a 400TLOD at the moment.
With anything less than 400LOD, the sim becomes worse than FS9.
At 400LOD, it is still playable. However, from a higher altitude, it’s a blurry mess.
Same thing here. As I said previously I suspect that all aircraft need to be recompiled because it seems that at release the sdk was broken so aicrafts may have been broken (also default ones).
Maybe with smaller aicrafts the performance hit is not so evident.
I don’t think it’s sloppy coding.
FS24 with 4K textures and ultra-everything can overload any current GPU. Asobo have added a warning message if retail memory is exceeded.
We have a responsibility to find the sweet spot, just under the VRAM limit.
Day 631.5 (lost count) since switching from a 3070 to a 7900XT, VRAM usage continues to be fine. I must have done 100+ flights so far from previously crippling aircraft with previously crippling aircraft. Only thing I have done is upgrade to 64gig of RAM as that was quite often going above 32gig and crashing my PC.
I do it because it looks better and it generally works perfectly fine for me for my type of flying. I normally fly GA aircraft lowish in VFR. And things look great and very smooth with typically 40-ish FPS. I mean REALLY smooth. I really do not like flying airliners as that simply isn’t my thing.
The only time I have any kind of issue is in the shown cases. And I only did that to provide one more data point with this issue. Lower TLOD would help reduce/eliminate running out of VRAM there, sure. But these cases are not the norm for my flying. If and when I wanted to do the occasional flight like that, I would temporarily adjust my settings accordingly.
FWIW I cannot really see frame gen giving me anything meaningful TO ME: I am not looking to get 60-80FPS in essentially all my flying when 40 works perfectly for me.
The old concept of to each his own applies I suppose
I beg to differ.

Though you and many others may be avid gamers who are expert in tuning for best performance, it is not reasonable to expect that of everyone who might choose to play FS-2020/2024. I am NOT an avid gamer and, (despite my vast experience with computer hardware and software), I am NOT an expert at overclocking or tuning things like memory timing, VRAM usage, or other of the “edge case” type scenarios typical of they hyper-gaming community.
My typical system is a middle-of-the-road, conservatively tuned system, tuned for maximum stability, not bleeding edge performance. -
It is also true that I might be out of touch with reality when I expect a game, (or any other piece of software for that matter), to do what it says it will do without unnecessary interference with other parts of the system.
-
In a situation where a system’s BIOS, CPU, memory, and/or graphical configuration and settings are critical to the successful use of the product, I would expect the product would be able to analyze the system - or provide a utility that can analyze the system - and recommend the appropriate settings, both within and outside the game - so that the game/software will operate properly within the constraints of the available hardware.
I feel it is incredibly arrogant for a software publisher - any software publisher - to have an implicit requirement that the end-user be a subject matter expert in tuning the software.
I do not know, nor can I know, exactly what the software wants so I feel that the software should let me know when it needs my help, and provide intelligent suggestions about what to do - and not hide them away in a tiny color-coded pop-up in the corner of the screen.
What say ye?
I don’t disagree with your comments.
Simple adjustment of the FS24 Graphics options is all I expect the users to do. Something like start at medium, check the VRAM, then move up to high, check the VRAM usage etc.
Asobo have colour coded the VRAM messages in the fps monitor - red if memory use is above the installed VRAM.
We have the necessary tools and controls within FS24, 10 minutes of test flights will give useful results.

I agree with this. Sounds like you are addressing me lol. But yeah, most fixes are way, way above my head. There are some here that have saved the day for me though, when I tried things that flooped up my sim. I say because you hit on an interesting thing with settings, and what the software wants. My sim is running fine with the recommended settings in Nvcp minus the Vsync setting. It performs well at these somehow. A lot higher settings than I would have picked for sure, but it is smooth as butter. If not smooth, I never change anything. Just close it and try later. Sometimes it’s hampered by a store update needed, sometimes a sim download, sometimes a reboot of PC, but 95% percent of the time it ends up server related(guessing). Most of the issues I have appear around the weekends when server traffic is prime.To this day it still keeps me from making changes to anything with hardware or OS. I’ve come to expect it sorta. I ck for updates daily, install as needed, reboot PC, open sim and fly most everytime. Default sim,FF mode for me. Optimised settings in Nvcp minus vsync on. Vanilla sim with some Bijan 2024 stuff, couple weather presets, and a few 2024 approved addons. Guess I’m a lucky PC dummy. Both sims are great on my AMD system with these recommended Nvcp default values. I still use both sims and they have exceeded my expectations after using these settings. Can’t explain it, but happy nontheless. Hoping it comes together for all
agreed, but the fact that the performance tanks and doesn’t come back up, even after leaving the offending area or lowering settings, points to sloppy coding to me
heck, even going back to the main menu doesnt fix it, you have to restart the sim to restore functionality
if you go over budget with the vram, its over, the sim dies
that doesn’t sound like good coding
if the performance tanks because you went over budget.. that’s one thing
but it should come back up.. right now its not doing it.. that’s why in my view its a bug
Yep. If the sim can detect the GPU overload and print it in red in the fps monitor, then it knows it must reset the GPU somehow.
Rebooting the sim is not a long term solution.
I’m sure the devs realise how bad that is, in fact Seb mentioned it two weeks ago.
I expect they can fix it by restarting the flight, but thats like handing the passengers a parachute and refund ticket. That’s not the way to run a successful career. 
My current settings are far from being ultra. Texture quality (which as I saw affected VRAM usage in general the most) is in medium. I’m not aiming for high FPS, 30 is more than enough for me. Still this FPS loss and literally unusable sim condition happens many cases. 30 FPS one second, 5 in the next. Even if I exit the sim session it stays 5 FPS for a few minutes in the main menu. Which part of it doesn’t look like as a coding issue to you?
(My config is pretty close to what Asobo has defined as enough for ultra at 4K. The only difference is that my 3080 has 10Gbytes of VRAM instead of 12 but since many report the same issues even with 4090 I have strong doubts it’d solve my issues. And I’m still not running the sim on ultra…)
I have been following this issue but not commenting because I think it is hopeless. I have done everything I can do to make this pig fly and will soon be giving up. I have spent a lot of time trying to find out how the autopilot on the 787 works and it still has bugs in it that have been there for maybe years. You cannot really put in complex flight plans and hope it will work. This plus the fact that the instrument labels are blurry unless I use TAA (which I cannot) just makes it too obnoxious.
I really would like to see this thing work but how long have we been working on this… for what a month. I know if I was coding this it would be a lot better fast but I have come to realize that this is going to run at the technology of their lowest common denominator… steam or the XBOX…
Anyway, I’ll probably try a few more things but I think this is close to the end for me. At least with 2020 I recall the labels on the instruments were crisp…
How long does it take FS24 to restore a sensible fps in the Main Menu, after stalling to under 10fps in the flight?
I agree, if coded correctly FS24 should clear out the (excessive) GPU memory when ending a flight. And a new flight needs free VRAM.
There are certain addons that can alter LOD dynamically and keep everything smooth automatically. But they get branded as “cheats”.
MSFS2024 actually has this feature natively now, but it doesn’t help me much because in certain scenarios I can turn LOD down to 10 and still not have enough VRAM, it only makes the sim looks worse. 
I’m also tired of tweaking my config to make it eat less VRAM. This is totally a bug. I have MSFS2020 on ultra with VRAM to spare, on MSFS2024 with it on LOW I peak the VRAM easily.
This isn’t normal at all, and not a “user spec not enough problem”
is there anyone here with a radeon card? i think radeon’s are free of this issue
If you set “dynamic” setting that also changes LODs or at least the effect feels similar. In case I turn it on set to 30 fps and my fps is for example 20-25 before, the FPS becames 30 after a few seconds but OLOD seems to get lowered a lot (might be other stuff too because not only mainthread but GPU performance gets better too). So it seems this setting does something similar like the other “cheating” tools. It was also mentioned several months ago when those other tools appeared that they use similar system for Xbox to make it possible to run MSFS and they are thinking about implementing it to the PC version too.
When I had 32Gbytes of RAM the time spent in the menu waiting for recovery sometimes lasted “forever” (so long I opted for a restart instead of waiting, more than 15 minutes). Since I upgraded to 64Gbytes the RAM usage is fine and I feel it recovers quicker too, sometimes only after 2-3 minutes. Might be that now the GPU VRAM “cache”, put into the RAM has more capacity than earlier but I don’t have enough knowledge about how DX12/MSFS manages this extra GPU memory “cache” function. So I can’t tell what to measure exactly about this cache operation and overall RAM capacity effect on it, other than checking in the task manager about the size of this cache (at the GPU performance table).
When it recovers it does the same way it’s dropped down, becoming 30FPS again from 5 in a second. And it’s almost always drops down to 5-6 FPS, like a standard value. Meanwhile GPU shows 100% usage but temps and power consumption shows that it works at 30% maximum.
I have a Radeon RX 68000 with 16g VRAM. running on a Gigabyte MOBO with pretty much the best AM-4 socket processor I could find.
The software-derived defaults are 99% “High” (as opposed to “Ultra”)
I have been working on getting the simulator to install and run without trashing my MSFS-2020 installation, (or crashing ), so I have had zero flight time yet.  (And with the granddaughters here for the holidays, there might not be much of an opportunity for me to touch it. 
)
However, I will be glad to report results when I can.
P.S.
I have started my own thread where I am documenting my own adventures with FS-2024.
You can follow my adventures there as that’s where I post progress first.
if, when you have time, you could report loading the a320v2 into jfk, that would be helpful
thank you so much
