SU2 here. I’ve recently tried the moving maps on the MSFS EFB (via the Navigraph charts app) and after several flights and tests I’ve come to the conclusion that the Moving Map - once I zoom in to the airport/taxiways level already at the departure airport - leads to a 2,5 GB extra usage of VRAM over time (about 3 hours of flight), which cannot be undone neither by disabling the pink moving arrow nor by entirely signing out of the charts app.
Now we know MSFS 2024 has some VRAM issues, so I could attribute some of that to it, but I have no idea why a moving airport map could ever end up using 2,5GB of VRAM.
I’ve double and triple checked this, once I uninstall the charts app from MSFS 2024 VRAM usage under the same conditions is 2,5 GB less after 3 hours of flight. Also the same happened when I used the in-game charts panel (instead of the EFB app) and even while using the moving map from within a 3rd party aircraft’s EFB (i.e. PMDG 777 or Fenix).
I hadn’t used the moving map before on MSFS 2024 so I can’t tell if that’s only since SU2 was released or had always been the case.

Having this same symptom, but I too cannot comment on pre-SU2 behavior because 2024 itself was practically unusable before that for me. But there is a definite degradation of performance over time with Charts loaded, and a definite uptick in both VRAM and RSS.
If I may also comment on a potential problem: the default Navigraph UI is sluggish in browser (i.e. on desktop) too. There really needs to be a much slimmer, less javascript-y version for in-game use. Any operation you undertake in Navigraph within the sim causes a stutter.
I’m on 14th Gen intel, on a 4090, all solid-state. Any clicks on the Navigraph charts UI in-game cause stutters as Navigraph executes script and transfer. I feel like the in-game UI is a bit ambitious with the amount of “presentation” it’s executing within the game threads. This was practically impossible to use in 2020 due to its heavy dependence on the MSFS main thread, but it is not “smooth sailing” in 2024 to any degree. Moving maps (i.e. follow ownship) work much better in 2024, but I dread to click a facility or otherwise trigger the Navigraph UI to do anything because it will stutter the sim, guaranteed.
This is the primary usecase of Navigraph for me: access to VFR charts in-game, especially in VR. But even in “pancake” mode I am experiencing performance issues, noting that, again, any time you trigger something in the charts UI it will cause an effect on the sim itself, not just the Charts UI.
This is, again, on top of slow-burn performance degradation over time with Navigraph charts loaded in-sim. (apologies for mixing cases here, but I strongly suspect they are related, there appears to be some sort of leaking but baseline performance is also kinda bad)
My specs:
Intel i9-14900KF
4090 GPU
128GB memory
Both Navigraph and the sim are installed on m.2 drives
And I have a fiber Internet connection at 1 Gbps (cable-limited in my case, my connection itself is 1 Gbps+)
