Brief description of the issue:
The sim freezes after a few hours, and at that point my “Shared GPU memory” (Which is RAM available to the GPU) is full, which should never happen especially since i have 16GB VRAM, which was also almost full.
PC specs and/or peripheral set up:
Intel 11900K, 32GB RAM, RTX4080

If relevant, provide additional screenshots/video:
Now i was just sitting in the main menu for about an hour, and it froze again. This time i got the graphics error popup with “DXGI_ERROR_INVALID_CALL (0x887a0001)”.
The freeze comes as soon as the Shared GPU memory is full.
In a flight it seems to take much longer for this to happen. A couple of hours sometimes in my case.
This is a perfect explanation of the major memory error MSFS has had during more than 1 year. Everyone can now understand the problem easily. Memory was never released properly, nor during flight, nor after returning to main menu after a flight and thanks to your explanation it´s clear also that nor even at main menu itself.
