Yeah that’s terrible.. fun fact is in the past I reported a performance regression in FS2020 and got ignored as well. I don’t know if they are really interested in that, unfortunately FS2024 is better in every aspect except VRAM…

I have spent sone time today, its a total mess. I have tried downing settings but its a slide show if i eithe take off or land at a reasonably sized airport. Tried simple GA aircraft and glass cockpit aircraft , total slide show. I did try a tarmac strip in the Caribbean that had no buildings, buttery smooth fliying around. I did some circuits. Soon as i select an airport with anything more substantial than a shed, everything implodes.

I also had a Sinclar ZX80 and played Flight Simulator 85 made in Microsoft BASIC. We had no problems with DLSS, FG, Nvidia Driver etc. lol, everything worked very well if the cassette tape didn’t have problems saving the data lol. Good memories and good times.

I really don’t understand why they cannot fix this. I just got SU3 Beta and its just as bad as ever. Slideshow <10FPS with any airliner. VRAM exceeding limits and warning dialog boxes popping up. This is completely ridiculous now. (5080 GPU)
I just did a flight with the PMDG 777-200ER from MDPP to TNCM. Everything went well, but on arrival the runway textures were very blurry and only loaded in after the rollout, accompanied with heavy stutters, 95% VRAM usage (16 GB VRAM) and a message that the used ressources exceeded the available VRAM.
After this update, I can forget about flying around larger intl. airports such as EGLL JFK etc.. it’s just not joyable. If lowered the texture quality, might as well go on minecraft on my side. Got a decent build as well, at the moment im running low-medium settings.
SU 3 is surprisingly a giant step backward in terms of performance. I went back to public Beta (SU 2 final ver). SU 2 is still the best so far.
SU 3 DLSS gives me flickering trees. FPS drop which was almost non existent in SU 2 comes back in SU 3, even more dreadful.

Ok, Microsoft are really the best sales people for NVIDIA.
I decided to order a 5090. I lost too much time in the settings screen and solving VRAM issues, instead of flying.

Yes. I had had better luck with the latest SU2 beta build, but I’m my last flight with SU3 beta, both the dedicated memory and the shared memory filled up at cruise level FL370. Lowered the TLOD and OLOD to 10 and the memory never freed up. 10fps or less.

Came here and made an account just to be able to comment on this thread because SU2 and VRAM usage has been the bane of my existence.
I have a good build: a 4070 Super with 12GB VRAM which is the recommended spec and I have a 5800x3d. But final approach is just a slideshow every time.
I’ve optimized and optimized, lowered my texture resolution down to medium and I refuse to go to low when I literally have a $1500 PC.
The more I thought about it… everyone talks about oh now we’re CPU limited.. GPU limited.. VRAM limited, and some point you have to accept we’re just MSFS limited 
Microsoft what even is this. This is not an issue of the LODs being bad. I should not need a 24GB VRAM card to play FS24 normally. You all have to address this ASAP, literally forget all the other stuff this is the number one priority right now. The VRAM usage of this game is horrendous. It’s just not even fun to play anymore, please fix this I beg of you.

Exactly this, I mean come on FS2024 was supposed to fix the issues and shortcomings od the performance issues of FS2020 but what we have gotten here is literally the opposite. It’s just the same old issues of stutters, low FPS, still main thread limited, and now with the added VRAM issues it is as bad as ever: the FPS may be a bit higher in general but none of that matters if every time you come in for a landing it is just a PowerPoint presentation…
Come on guys, what are we doing here? Seriously?

Hello,
Tested out FS2024 with SU2.
I have an Intel UItra 9 285K with an RTX 5080.
In essence, if I manage to leave 2 Gb of VRAM free at all times, it will not crash.
If I reduce this margin, it will CTD at some point, likely when another application is using VRAM or when FS2024 suddenly loads something.
To help with VRAM management:
- I have disabled reBAR and it gives me about 1 Gb of extra VRAM. I’m not sure why… There is an entire topic about this on this forum
- I have also switched most of my applications to use Intel Graphics, and that keeps my Nvidia GPU entirely dedicated to FS2024 and avoid memory spikes (especially when using browsers for example or sim applications).
I use TAA, FG DLSS X4 (set in Nvidia App), and all options are on Ultra, except for:
- Distance LOD set at 100
- Texture resolution down to High
When the sim is in-focus, I have 144fps (screen max fps) with FG. Out of focus, the real framerate is about 40 up to 60. No stuttering at all.
On this last point, if I set Texture Resolution to Ultra, it will CTD quite rapidly.
That’s coming back from being unable to simply launch the game since SU1.
Before SU1, I was able to run everything at Ultra, LOD distance at 200.

Ok folks. I have been suffering from terrible performance since su2. Today, because i must have wanted more punishment, i decided to go into DLSS swapper and swap back to the DLSS file and Framegen file and FSR file back to the original … because first thing I did after installing SU2 I updated NVIDIA driver , clean i stall then went to DlSS swapper. I dont know if Asobo did anything but i had a perfect flight , silky smooth out of KRVL , did a couple of circuits. Here the thing, I dare not touch my settings…but i could not resist a quick look LOL…and the VSYNC is on, I didnt turn that on, and frame Gen is off. (I think i turned if off). But anyway i post to say, if you are a tinkering with DLSS files, put them back and see if that helps you. Also i am using GSYNC in Nvidia app, i am wondering if there was some conflict going on. Good luck and let me know how you are getting on. Cheers Steve
I started with a clone of the Ohio Superboard, a single-board computer you actually soldered the chips in yourself (8k RAM+VRAM, 1MHz). I learnt a lot from that: added some more RAM, routed it to the display so effectively running two graphics units into one display; a bit of re-wiring doubled the speed, some more quadrupled the cassette interface speed; I intercepted the software driving the keyboard to write my own cursor-controller/editor. I even wrote a game called “Burglar”, and got it published in a magazine. (Someone later revamped it when the CPC6128 came out, and included it in the manual under the title of “Raffles”, which some people may remember.)
So if there was a problem with “VRAM” in those days, we fixed the hardware/software ourselves. Nowadays with literally a million times the VRAM, the app still runs out of memory! How has the hardware so outpaced the abilites of the software engineers?
It didn’t solve my problems, It won’t solve your problems mate. Better keep your money.
I can’t imagine your VRAM usage is going over 32 GB?
7900XT Report - After a longish flight yesterday in the A321 Neo (yes, finally this plane is fixed instead of the jittery ailerons on landing), down to Faro from the UK, everything was fine. Vram was most 11 or 12 gigs all the way. Sadly though, it was a bit of a stutter fest close to touchdown which seems to be an issue since release. I feel this has something to do with caching, if I fly back to the same airport, no stutters.
I’m back on 2020 today, with DX12 enabled and it’s been glorious so far. Great to be able to see my beacon and nav lights too.
