b580 Memory Leak in dcs world

[FLYing59]

i use win11 25h2; i5-12400f; arc b580;32g,3200mhz memory;

In single-player mode, VRAM usage is relatively low and can handle 2K at 60fps.

However, after entering multiplayer mode, the 12GB of VRAM is quickly exhausted, causing the graphics to lag severely, and the longer it runs, the lower the frame rate becomes. Even after exiting multiplayer mode, the VRAM is not released.

At this point, opening a single-player mission also results in very laggy graphics, sometimes dropping to only 20fps.

p1 single-player task
p2,3 open a multiplayer game
p4 back to the top,the vram is not released
p5 open a new single-player task

I have tried clearing the shader cache and lowering the game's texture quality, but the VRAM leak in online mode still consistently occurs.I have generated the SSU logs

Hello FLYing59,

Thank you for the quick update.

Upon initial checking of the SSU, I found out that the BIOS of your board and the Graphics are not updated.

Here are my initial recommendation and kindly update me if these will help with the issue.

1. Please update the BIOS of your board, here is the download link: MAG B660M MORTAR WIFI DDR4
2. Please update the driver using DDU method. Kindly refer to the link below for the steps on how to perform DDU and the direct link of the latest driver:

Hello FLYing59,

Thank you for the update.

I may need to further investigate this issue and try to simulate this in our lab. For me to do that, I need to gather additional information.

1. What is your game launcher?
2. Please send a screenshot of the game's Graphics settings.
3. Kindly tell us if there is a specific place in the game that would trigger the memory leak

If you have questions, please let us know. Thank you.
