Dont understand why ms2024 has not got the dx11 option

I feel like this defeats one of the major selling points of using MSFS. 

It does but that's kind where things are at if people are running tons of addons (ESPECIALLY 2020 addons in 24).

I was looking at some differences between runtimes for 20 and 24 native addons and it's like night and day.  The true 24 stuff is much more efficient.

Another issue is that not all devs are actually making fully native addons.  But some claim they are "2024."

I am not using any scenery or aircraft addon personally, the VRAM usage is horrible with the default scenery and aircraft.

In fact, it is a recognized issue that Asobo is trying to fix, as reported in the bug table I linked previously.

PG is part of the default scenery and is supposed to work without tanking the framerate even with 16 or 24 GB high end cards. Disabling PG is NOT a solution. Besides, Dubai does not have PG and the VRAM fills up just the same at OMDB.

It's not a permanent solution but the sim still looks really nice without it.

What settings are you running to get the resource popup still with default stuff?

I'm not saying it's not an issue because it is.  But the 2020.addons in 24 will spike vram the moment you load at the ramp.

To take advantage of particular DX12 features that are now baked into the game engine.

How bizarre...I just logged into Avsim to explore why the heck I hardly see anywhere near as much VRAM in use compared to when I first installed 2024 a three months ago or so.  I was intending to ask if others have had this experience and noticed this thread.  And the reason I'm concerned is that in complex settings I noticed in cockpit panning has really suffered of late even in super easy to process planes like AS CRJs.  I surmised it had to do with changes in coding to effect more use of system RAM as that is up at least as much or more than VRAM is down here.   No matter where I am even in complex planes 14GB is about it, whereas previously I was seeing up to 19Gb in use.  Right now in CRj700 over Germany:  10.4Gb.  SRAM 21Gb.  I've now seen SRAM up to 34Gb, way higher than previously.  Using SU2 FWIW.

I’m not seeing any VRAM usage above 22GB so far, RAM is around 28-30GB usage.  BUT, I don’t use DLSS which will consume more VRAM.  I stick to SSAA (aka TAA=200).  

I do have A LOT of add-ons (FS Traffic, SimBrief, FSLabs, PMDG, GSX, Orbx, iniBuilds, FSDT, etc.)

How is your VRAM usage without DLSS/FrameGen?

But in case you didn’t know, using VRAM is a performance benefit and should be used as much as possible in order to keep FPS acceptable.  Have you tried the dynamic performance option in MSFS 2024 to see if that helps?

Your post intrigues me!!!

You mentioned that your RAM usage is around 28-30GB. I remember seeing those numbers the first three or so months after 2024’s release. I ended up upgrading to 64GB from 32GB because I would run out of Physical RAM. 
 

Now I’m not seeing anything over 20GB of physical RAM being used. 
 

All that to ask….

Do you think there is something the simulator is doing wrong on my set up? Or in other words? Why on earth has my RAM usage been cut in half but my VRAM usage still going through the roof? I don’t know if you can even answer the question. I’m more or less thinking out loud.

With high-end settings and only volumetric clouds at Ultra, DLSS frame gen and TAA at 3440x1440 I don't get the message, but I have 90% VRAM usage at OMDB with the A320 v2. Borderline conditions.

I get the message with Ultra settings, that as of today are not usable with 16 GB of VRAM.

PG was never an issue.  I just turn it off.

Isn't the real issue using highly inefficient 2020 textures in 2024?

As long as assets are native 2024 format you should be good IMO.

I doubt that.. .. and even if that was the issue then ASOBO needs to hasten the conversion process for their own assets because this issue is happening on stock installs.

Yep, can’t use Ultra with 16GB VRAM … same VRAM warning message on my 9070XT 16GB on my other PC.

I know this is NOT popular and many probably don’t want to hear it … but using more RAM and more VRAM is better for performance.  RAM operations are much faster than non-volatile storage (aka, HDD, SD, M.2, U.2).  And VRAM is even faster than RAM which is why you want to use as much as possible (be it AI/DLSS or other GPU accelerated operations).

In order to do any sort of metric compares, a detail list of the following would need to be provided:

1.  What version of MSFS 2024 (SU2, SU3 Beta etc.).

2. List ALL the details in your graphics settings (not just a few).

3. What Add-Ons are active and being used and their versions if applicable and are they native 2024 builds from 2024 SDK or compatibility products from 2020?  In addition, list all the settings related to those Add-Ons (especially AI Traffic and/or weather).

4. Provide the exact location and weather conditions.

5.  Use tools like RTSS, nVidia overlay, AMD overlay, Intel’s performance monitor tools to log the data to file over time.

Not without much more information as described above.  There are so many variables that can determine VRAM/RAM usage that need to be examined and listed and compared.  Frankly, it’s a lot of work, but it’s how you separate fact from fiction.

I know there are many “this is the best settings for MSFS 2024” and “how to get rid of stutters” videos on YouTube, unfortunately most of them don’t address Add-Ons and don’t log (metrics) over time and don’t run the same exactly flight and same flight settings.

Unfortunately what often happens is the easy answer “Asobo did something” … but does that actually identify the problem?  Does it help you today?  Does it just make you walk away from Flight Simulation?

From a user/consumer perspective “I just bought the game, I don’t want to do all this to figure out why I get VRAM warnings” … a valid response.  BUT, what should Asobo do?  Not allow graphics settings if it determines your hardware can’t support it?  Not allow Add-ons to work if they don’t meet a specific performance threshold determine by Asobo?  It’s a slippery slope which is why I think Asobo offered the “Dynamic Performance” setting.

FYI, I’m a long time software engineer, project manager, software development manager, and CTO.  Please don’t shoot the messenger as I DO understand the frustrations.

I know many like “quick answers”, but in my experience “quick answers” are rarely the right answer and can send users down the wrong path ending in frustration.

Makes no sense here.  The 4090 has 24Gb of VRAM, and now I never see it over 15Gb and that includes all VRAM in use for my second display and other open apps.  And average VRAM total in use is closer to 12Gb.  Flying over Germany a little while ago, 10gb and change in the AS CRJ700ER.  ALL settings are at ULTRA and have been.  I'm miffed for the opposite reason:  all that fast VRAM is sitting idle being replace more now by much slower system RAM.

What resolution? Dlss it taa?

Lets talk about virtual ram usage, i have over 30 gb. This is the ram that is written on ssd or m.2. Why asobo doesnt use system ram instead, i have 64 gb of sram and thats more than enuff to put the whole virtual ram usage to more speedier system ram. 

 Go figure what they are doing with the code

3440x1440, TAA, and as I say, ultra everything.  Was just at KJFK in Fenix 320 CFM:  12.4Gb in use by the sim, and ~2Gb in use by everything else.  

If MsAsobo can't fix this, then they can greatly subsidize all these incredibly expensive GPUs that cost thousands with over 20gb of Vram.   I have a 4080 super with 16gb and its a fantastic performing card.  This issue is all Vram.  Performance without Vram maxing out, is solid with great fps, frametime, and smoothness. Get close to 13gb vram and it becomes a stutter fest.  Not long ago, 16gb vram was overkill.  Having answers like turning stuff off, and disabling addons, seems ridiculous.   Other games that are demanding dont have this issue.  In fact they dont even come close to 16gb usage.  

This should  be a priority fix.  So far I don't see much talk about it in SU3.
