Issue:

What causes the lag or delay in moving the mouse cursor or performing selection box operations in ZWCAD?

Causes:

The system has updated the graphics card driver, but the software has not adapted to the latest graphics card, resulting in lag or delay when moving the mouse cursor or performing box selection operations.

Solution:

  1. Right-click the mouse on "This PC" and select "Manage".
  2. Click "Device Manager" and then "Display adapters". Disable one of the graphics cards listed there.
  3. After completing the operation, reopen ZWCAD and you will find that mouse movements or box selection operations are no longer laggy.
