Well I’ve been using DX12 in 2020 for a long time without these VRAM issues present in 2024. It’s something they are doing different in 2024 that is the issue, not DX12 itself.
I‘ve been using DX12 in MS2020 even with my older RTX3060 -now with RTX4070Super. Not having this issue in MSFS2020.
If you can see and correct any Vram bugs using task manager, please post the fixes. You would make a lot of people happy.
This is complicated which is why Asobo has enabled memory logging with SU2 Beta. And if you notice the issue has been bug logged so Asobo knows there is a Vram issue.
That’s not possible with 2024. I don’t recall the exact reason but I think it has something to do with streaming.
wow, there is a setting lower than LOW? cause i’m trying LOW tex res

You should disable resizable bar in your bios. Also know as c.a.m or s.a.m
I’m afraid I no longer have faith in Asobo’s excuses for not doing things.
Before FS2024, the excuse was always that they were using legacy coding, and that the simulator needed to be rebuilt from the ground up. FS2024 was the perfect opportunity to do this, but we have now ended up with more problems and worse performance (for me at least).
If Asobo decided to implement DX11 as an alternative, they could do it - though probably at the expense of some other features and only after a lot of recoding. It’s this last one which is probably what’s stopping them.

Will try after disabling it and will came back to report. Thanks.

In my case (amd 9070xt), since i have disabled resizable bar in bios, the vram problem has gone away. Less stutters, everything smoother.
(Msfs 2024 su 2 v1.4.10)
In my opinion, there’s a problem with rebar implementation in msfs and/or in the gpu driver
My Dell PC Bios doesn’t have “Rebar”, and yet I see the VRAM problem in FS2024 all the time. But not in FS2020. The Rebar, whatever that is, is not a cause in itself.
I tested with resizable bar ON and OFF in the photogrammetry of São Paulo and the difference in the amount of VRAM was significant. I removed all wildlife, air, land and sea traffic because they can be in multiple positions. I kept the same time of day with clear skies.
REBAR off in my case (AMD RX7600 8GB) helped the VRAM usage to be lower. This is a good sign.

Its can me called S.A.M of C.A.M.
always its a catch on this fast tricks . GPT says that will be compromises in visual quality . do you see something different in image quality with rbar off in any way ? thanks
Well I’ll be dammed.
I tried again and have not had an any stability issues as I did before. I am noticing that the audio popping and stutters I had been getting are gone after testing with edge Rebar off on the bios. Seems promising.

No visual difference here
No visual difference and less stutters.
Thank you for confirming what I was going to make a new post about. There is no choice but to use DX12 in MSFS-2024… saves me from having to ask the question.

Just update. I just completed a flight from KDEN to KBOS with REBAR off. This has been the smoothest that MSFS 2024 has ever been for me. No stutters, no cracking audio, no popping. There’s something here.
It’s been fantastic for me as well, and I even tested other graphically intense games to see if they were negatively impacted and they were not. Didn’t go so far as to do extensive A/B testing with them, but just confirmed they were still performing at a high level.
It does, however, seem like this impact varies from user to user, with some reporting no change, and even others reporting things getting worse with REBAR off.
And to throw another moving target into the mix, I also included the disabling of Hardware-Accelerated GPU Scheduling and saw an even further increase in performance (lead by a decrease in VRAM usage/increase in VRAM availability).
