Symptom:

After the IPC runs for a period of time, the whole system becomes laggy, but the planning and production workflows of Mech-Vision/Mech-Viz can still run normally.

Possible Cause:

The HAGS (Hardware-accelerated GPU scheduling) feature in Windows 11 causes system lagging.

Notes:

  1. This issue can be reproduced in software versions 2.1.2 and 2.2.0, and is not related to the software version.

  2. White-box verification confirms that there is no memory-leak issue in Mech-Vision/Mech-Viz itself.

  3. Similar lagging behavior has also been reported for other software on Windows 11.

Solution:

  1. Disable HAGS in Windows settings.

    1. Open Settings. Press Win + I to open Windows settings.

    2. Go to display settings. In the left pane, select System, and then click Display.

    3. Open graphics settings. In "Related settings", click Graphics.

    4. Change default settings. Click Change default graphics settings.

    5. Turn off HAGS. Switch "Hardware-accelerated GPU scheduling (HAGS)" to Off.

    6. Restart the IPC. Restart the IPC to apply the settings.

  2. If lagging has already occurred, press Win + Ctrl + Shift + B to reset the graphics driver and temporarily mitigate lagging.
