Yeah, I read it. And Recommended specs etc is some BS Ive never bothered with.
If there is a Vram bug, great! And I too hope they fix it.
But I dont see it. It was same in dx12 2020, although worse. So 2024 behaves much like I expected it to.
But if there is a bug - thats not good.
Also remember Asobo tests are with a clean Win installation with just msfs2024.
A 5yr old 2080 with tons of BS on it, might behave differently.
As I’ve posted before. Going to specific scenarios where the VRAM gets maxed cannot be relieved by changing any settings.
In my post above where I posted a video, you can see that once I encountered the bug at KJFK. I attempted changing the settings to alleviate the problem. None of it worked. Even demonstrating that TLOD @400 vs 10 did not change the VRAM that being utilized.
**What we ALL need to do is find the areas where it occurs. The aircraft, share your settings , specs and post your findings. **
**I am trying to get everyone to reproduce the area where I get the same VRAM usage which is KJFK with the Inibuilds A320. **
Then switch to the Cessna 172 and see if there’s a significant change.
this is, in fact, the point
now… leaving assets loaded can be a sound practice, eg, if you expect the user will need those again shrotly, so, leaving an aircraft loaded after quitting a flight does make sense in case the user starts another flight with the same a/c
but if the user then loads a different a/c. then you need a sound garbage collecting strategy with a well-thought out plan to unload the assets that are no longer a priority
i get the impression that the sim just loads and loads and loads and loads disregarding how much actual vram is available, so, the sim’s usability suffers
maybe not a bug per se.. more like sloppy coding practice.. and the old answer “just add hardware, and it’ll run good”
with 8gb, this combo is guaranteed to kill it, no matter the settings, even if you pull everything down
Hello Guys! I have a RTX 3070, combined with Ryzen 7 5800x and 32GB of RAM. I have a M.2 SSD just for MSFS 2024 and my version is from XBOX Gamepass.
I think that I may have found a workaround for the strange VRAM usage, and it was (or is) related to cache. I already did this in MSFS 2020, but didn’t think that would help in 2024 too.
First, you have to go to Nvidia Control Panel, disable your Shader Cache Size and restart your PC.
After restarting, go to LocalLow folder inside of AppData.
Then, go again to Nvidia Control Panel and return the Shader Cache Size to Driver Standard.
Just restart your PC and open MSFS2024.
I like to do some flushdns too, but this just cleans the network cache. it may help you with loading times, so…
Open CMD and just
My results are… good, I guess. No FPS difference, but my VRAM isn’t in extreme use anymore. I’m using the Optimized Settings from dwindlingfps on Youtube, but I have Displacement Mapping ON, Terrain Pre-Cache in ULTRA and Volumetric Clouds in ULTRA.
I play in 1440p with the setup already mentioned. Here are my results flying over NYC.
It’s painfull doing this everytime I’ll open the SIM, but… It worked.
Hope helps you guys too!
Cheers!
The problem is that it’s doing it even on 4090’s with 24GB of VRAM. I’m also confused on why you believe it’s guaranteed? Many users in 2020 with DX12 have used a 3070 with AI traffic and add on scenery and managed to get it with medium settings. I have most of my settings optimized in 2024 at medium and I’m still getting VRAM overused.
Can you try your findings with a complex airliner over NYC?
sorry poor choice of words on my part
i mean, in my testing, i found that combo makes the bug manifest itself consistently, with pretty much all settings, the ini a320 and the jfk airport are lethal to vram use
in fact, with low settings, its only sitting on the runway that’s a problem, i can overfly jfk (in the a320v2) with no problems, but if i land, then its 5fps
I regularly clean install Windows 11- Just did last week. That has nothing at all to do with the problem.
That was a reply to to Recommended specs:
“Why doen’t my 2080 run 2024…its within Recommended specs…etc”.
Asobo tests with clean Win install with just 2024 might run differently than a similar specced 6yr old 2080 with all kind of BS on it.
Otherwise I can also easily reproduce Vram exceedance on my 4080 in 5120x1440: just push TloD everything to Ultra…boom - Vram exceeded - stutters and low fps.
But those changing to low settings etc, and dont have any difference in Vram usage - that more weird and might be a ‘bug’.
Keep digging 
It works on my laptop，thanks for help
For me my FPS and VRAM usage is better after I turned off ray tracing shadows 8gb vram usage and around 40fps everything high LODS 65. 4070
Using the A320 V2 in JFK in medium settings res is in 1440P
CPU:17600KF
RAM:32GB 3200MHZ
GPU: RTX 3070 TI
SSD: M.2 500GB
Holy brightnes:D but feels weird that you only have around 50fps on medium
because of hdr screenshot so that is so bright
I don’t want to jinx anything, but I made a few changes and have been able to avoid the issue since making the changes, including recreating some of the scenarios that previous caused the issue. Here’s what I changed:
This is in 4K with an RTX4080.
I just departed Heathrow in the A330 with live traffic and heavy weather and FPS (with FG on) never dropped below 40. Once I got above the clouds I was seeing 70-80. Once I got away from the city a bit I was seeing around 110. While on the ground at Heathrow VRAM peaked around 13.5/16.
I have a 10 hour flight to Orlando ahead of me so who knows, this might all come crashing down once I approach that airport, but so far so good. I’ll report back.
I still don’t doubt there’s some bug present here, but wanted to share this in case it helps others.
whatever i try to optimize the setting nothing works well, i just gave up
I think ray traced shadows has somekind of vram bug cause my vram usage dropped by 2-3gb when turning it off (well flightsim.to frankfurt has bad vram usage but atleast fps is good :D)
Yup. Similar I do on my 4080 in 4k (ie almost 4k 5120x1440):
Texture resolution High or Med (don’t see any difference), but Vram reduced considerably.
Ray tracing off.
Trees below Ultra.
TloD 150 right now with Fenix etc, but can set that much higher with the 172/GA.
Displacement mapping (or what its called) off for airliners (more important for bush flying).
Im on TAA though, but works fine. Most importantly Vram is never exceeded with those settings.
So think you’ve found suitable settings there for the 4080 in 4k. In GAs you might of course increase settings… if you bother.
I am finding that optimizing the settings etc. only postpones the onset of the problem, but doesn’t solve it.
Once the VRAM peaks over into the shared RAM, and if that goes up to, say, more than 3GB (of shared RAM), then it won’t go back down again, and the FPS won’t recover, unless you completely reset the sim.
Updates from my 7900 XT adventures… VRAM usage has been absolute max 13/19.75 on high/Ultra settings, TLOD 200, OLOD 200, RT shadows on or off, probably lose maybe 5fps with RT on, at 1440p upscaled by 20% to 3072 by 1728 (looks nicer).
I’ve also flown from EGLL to Maccosim EGCC, KJFK to Philly, KLAX to KSFO, a longer flight from LEAL to EGPH using a mixture of Ini aircraft and the Fenix. No VRAM overspill, not even close.
My biggest issue now is, running close to max system RAM, 31.1/31.9. 
As well as encountering numerous known bugs and the odd CTD when ending a flight (happened on my 3070 too).
Further UPDATE: And it just happened, vastly exceeded System RAM (32gb) and poof… computer crashed lmao.
@CatMod-Bug-Report Apologies for tagging you. I want to provide data behind this bug that can hopefully make it to the engineers for analization.
I flew cleanly from a default (autogenerated) airport, KABE. To a handcrafted airport KJFK. I also recorded the whole flight to provide not only the system data, which I logged using HW64 (added to this Google Drive for public view). The areas where I ran into issues are highlighted in yellow. I highlighted in red, when I approached the terminal and got the maximum VRAM usage
The video shows that VRAM gets really close to the max as I approach the KJFK final. It really becomes a problem around terminal 5 / 3. I can reproduce this every time, regardless of the aircraft I am using.
I hope this helps. (P.S) My Youtube comment has linked the key moments in the video.
