The Visual Performance Cost
By default, when you click and hold the title bar of a window in Windows 10 and drag it across your screen, the entire contents of that window (text, images, playing videos) move smoothly along with your cursor. This is controlled by the “Show window contents while dragging” visual effect. It provides a fluid, modern feel to the operating system’s window management.
However, constantly redrawing the entire contents of a complex application window as it moves pixel-by-pixel across the screen requires significant processing power from your CPU and GPU. On older, low-spec, or heavily loaded computers, this can cause the dragging animation to stutter, lag, or feel unresponsive. If you are prioritizing raw performance over visual flair, or if you are working on a very slow machine, disabling this feature is one of the easiest ways to make the desktop feel faster. When disabled, you will only see a wireframe outline of the window while dragging, and the contents will only redraw once you release the mouse button.
How to Turn Off Window Contents Dragging
You can disable this specific visual animation via the advanced system performance settings.
- Click the Start button and type Advanced system settings.
- Select View advanced system settings from the search results. This will open the System Properties window directly to the Advanced tab.
- Under the Performance section at the top, click the Settings… button.
- A new “Performance Options” window will open. Make sure you are on the Visual Effects tab.
- Scroll through the list of effects and look for the checkbox labelled Show window contents while dragging.
- Click the checkbox to remove the checkmark.
- Click Apply, and then click OK to save your changes.
The next time you drag a window, you will notice it feels instantly more responsive, as Windows is no longer struggling to render the internal contents during the movement.
