ISSUE DESCRIPTION

1. Description of the issue:
   when booting after few secs fps tanks, vram is over the top

2. Did you remove all your community mods/add-ons? If yes, are you still experiencing the issue?

no mods, vanilla msfs2024

FREQUENCY OF ISSUE

How often does this occur for you? (Example: Just once, every time on sim load, intermittently)
every time, time of occurence may vary from immediate to after some minutes
did occur from low to ultra default graphic settings

even with cessna 172 from low to high default presets vram usage always to the max or over the available max

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue.

1. select plane and start the flight
2. even before initiate the flight after loading the bug may occur

YOUR SETTINGS

If the issue still occurs with no mods and add-ons, please continue to report your issue. If not, please move this post to the User Support Hub.

1. What peripherals are you using, if relevant:
   no periphals used

2. [PC Only] Are you using Developer Mode or have you made any changes to it?
   dev mode is used only to check performance status

3. [PC, MSFS 2020 Only] Are you using DX11 or DX12?

4. [PC Only] Many issues may be due to an outdated graphics card. Please state your Graphics Card Driver Manufacturer (NVIDIA, Intel, AMD) and Version (Learn how to find your current graphics card driver version):
   latest nvidia driver

5. [PC Only] What other relevant PC specs can you share?

That’s exactly my biggest problem at the moment!
Specs:
OS: Windows 11
CPU: AMD Ryzen 7 3700x
GPU: RTX 2080 Super
RAM: 32GB
Bandwith: 250 Mbps

[chatnyurur]

I exactly have the same issue.

specs: amd ryzen 7940, rtx 4070 8 gb, ram 16 gb

[manny732]

Same issue with me.

Ryzen 9 7900x
RTX 3080 12 GB
RAM 32GB
OMEN Monitor 2K

[Foxhound6050]

same issue

[nikthetrip5023]

another example at JFK

2024 (high preset, no RT)

2020 (all ultra, tlod 200, fsltl on)

[jaxgator17785]

Are you using the latest DLSS version (3.8.10.0)? MSFS 2024 installs with version 2.4.12.0.

I swapped the files with DLSS Swapper and saw better performance.

[AlexLegend165]

There is no way FS 24 has DLSS 2.4 since the game has the Frame Generation option which is DLSS 3 exclusive

[nikthetrip5023]

i did the update (both dlss and frame gen) though i am not using dlss becase it looks horribly compared to taa when you are in the cockpit, screens are way too blurry and have ghosting

[jaxgator17785]

This is what I saw before swapping the files. Is that not the version number?

Yes

Provide extra information to complete the original description of the issue:
•
I have abnormally high VRAM usage, especially in any of the inibuilds airliners to the point where it becomes unplayable. Why Inibuilds was hand picked to have their planes featured in 2024 in the first place blows my mind- they are notoriously known for being the worst at optimizing aircraft in terms of performance.

I get excellent performance over the middle of NYC in other aircraft, but even if I’m over the middle of the Atlantic in an inibuilds, VRAM is absolutely cooked (12gb and higher) resulting in seizure-inducing single digit frames.

If relevant, provide additional screenshots/video:

Use your imagination.

[nikthetrip5023]

again, in a cessna 172 settings medium to high compared to all ultra msfs2020

2024

2020

[Mgking777]

There is definitely something wrong. I once again spawned with an A330-300 at EDDH (default airport, no addon, no traffic) and had a good smooth start with 30-40 FPS. But suddenly, about 2 minutes later and out of nowhere, it dropped to fricking 6 FPS. That makes no sense.

[nikthetrip5023]

medium preset (4070ti, 7600x)

2020 all ultra tlod 200 fenix + fsltl

[chatnyurur]

If there are others like me who start with high FPS but then experience a severe drop in FPS after a short time, I think I may have found the cause of the problem. When I pay attention, I notice that when I get high FPS, the GPU temperature goes up to around 72-75°C. However, when the FPS drops to 10, the temperature drops to around 60°C. I suspect that the GPU is somehow reducing its clock speed, which causes the FPS drop. I would call it thermal throttling, but 75°C isn’t a high temperature. (Asus TUF A15 gaming laptop, RTX 4070 GPU) I still can’t understand why the GPU clock speed drops. Other than that, I’ve never experienced this issue in any game before.

[NAKKIVETURI]

I’m having exactly the same problem.

[Fornax4188]

Have you tried lowering texture resolution?
It needs to restart ms2024 to take effect.
You obviously exceed Vram limit.
There is barely any difference with Texture Resolution Ultra-High-Medium.

On my 7900x3d and 4080(16gb vram) in 5120x1440 (ie almost 4k) I have to reduce Texture Resolution to not exceed Vram limit.

Helps a lot reducing Vram usage.

Can’t get FrameGen to work though…

[chatnyurur]

If we still have to lower the graphics settings with an RTX 4080, it’s better not to play this game at all. It’s clear that the game has obvious technical issues. Hopefully, the developers are aware of the problems and will find a solution for this optimization issue as soon as possible.

[Fornax4188]

Not really. Texture Resolution has almost 0 impact on visual quality.
In a 1920x1080 resolution I would have no problems. But a 4080 in 4k Im happy to lower some settings…

[chatnyurur]

“Can’t get FrameGen to work though…”

what did you mean with this btw, what kind of issue do you have with fg?
