As promised: See at 20 minutes
You can see the fps drop within 30 seconds. The landing fase is incredible… WHY?!
Really sad Asobo!.

This is a problem of too high graphic settings in combination with ressource wasting addons. EDDF, a large air liner and a external addons are far too much for 12 GB VRAM.
Your VRAM is overwhelmed, you have only 12 GB and only 10 available. You have to reduce your graphic settings in general, in particular the traffic settings (cars etc.). Additionally stop background tasks consuming VRAM (there are several, otherwise the availabiel VRAM would be higher).
Last but not least the addon talking to you (Checklist entries etc.) causes a lot of stutter. It is obvious, that the stutters beginn every time the addons tries to talk to you.
I’m pretty sure, it will be possible to tune your system in a way, that more or less no stutters occur with only minimal visible impact.
As I said: SU4 is better, than SU3, but it is no good idea to keep the old settings from SU3. Since the ressource consumption of certain settings has changed significantly, all settings have to be optimized again.

Yes, in my experience Firefox is the worst hog. Chrome is better, but best to kill them all. My 5080 is running at 60-70% capacity for GPU computing but slowly in inching up to 90%+ for VRAM when I increase parameters to improve image quality, e.g. texture resolution ort TLOD.
FYI,
This was with the same setting I had in 2020 incl multiple addons (OLOD & TLOD at 100). I could have everything in the green but with way worse textures in 2024. VRAM is still killing, mega FPS drop in the descent so it’s SU3 all over again. With 1.6.33.0 it was nice and smooth, with 34 the result as seen in the video. 34 was introduced 1 day before they went for a holliday, probably without testing it first as usual. We are doing that. They just don’t care.
So 2024 is for me still a major downgrade and back installing 2020 with everything smooth and a wasted €140,- so far incl multiple addons etc.

I see nothing wrong here cough, not even a custom scenery or any mods installed.
just Asobo 737 max in LOWI lmao.
Asobo will never fix their horrible VRAM management with DX12.
It was like this in FS2020 as well for years.
And now DX12 is a forced API.

For comparitive purposes, you should try the same flight using only the stock sim and the same graphics settings but with no add-ons.
You don’t need external or complex addons to overwhelm your VRAM. Your graphic settings are way too high.
HDR, 4k native and Ultra settings: that is absolutely crazy with 16 GB VRAM. I have some settings on High, all traffic settings are lower, and DLSS Quality activated. That is working nice with 16 GB.

I have everything on the lowest settings and VRAM is still maxed out like crazy. This wasn’t the case before. Framerate cut in half, jumping around between 80 and 40Fps without changing anything to the settings or the sim.

What is “before”? SU3? And how much VRAM do you have? What scenarios are you flying, and which settings do you use?

Yeah i noticed in HWinfo my virtual memory is going red all the time in msfs 2024. 5080 16gb. I never had the hwinfo untill very recently though so not sure how long it’s been happening.
I have textures and clouds at ultra, LOD 200. Aircraft traffic/sea etc is off or lowest settings.

I have an ASUS 5080. The textures are still a killer. I set to Low. You cannot tell the difference unless your nose is on the runway

Cheers ill try it thanks.
Yeah i think the reason i might have been stuttering is because my vram was maxxing out, do you think this is probably correct?. Lowering textures to high instead of ultra seems to have solved it, might need to test a bit more but seems like thats the reason.
I guess, I missed the “build versions”, but with a 16GB 5080 I see mega stutters. Then checked the GPU mem usage: 15GB in Taskmgr, in 2024 (Debug mode) it jumps over the max 15something GB max available causing the stutters (FPS jumps between 40-80) Everything low, 2.5K res.
Tell me how it turns out. BTW, if you are using the registry hack that displays DLSS values to screen in real time, that uses VRAM also.
5080 users should stick together. Mine is so heavy I have to carefully set the bracing to keep it stable… maybe just in the ASUS MB.
As already mentioned: Ultra Settings with 16 Gb VRAM is not a good idea.

VRAM can also be used by apps running in the background. A single open browser tab can use up to 2 GB VRAM. That is of course missing in the simulator.
Although MS has improved the VRAM situation in SU4 signigicantly, you have to take care about your setup and configuration:
-
close all unnecessary background apps
-
chose appropriate settings. “High” is a good starting point, and then you can reduce some settings, in particular traffic, but maybe also terrain caching or texture resolution if necessary.
-
Raytracing Shadows are also consuming much VRAM.
-
And it is recommended to use DLSS Upscaling in order to reduce the render resolution.

Does using HDR use much vram ?
It depends. It uses more VRAM, but how much more depends on the resolution, scenery and objects.
