High CPU usage with spacedesk over USB
Quote from alierdem3822 on 04/08/2026, 01:36Hello,
I have a performance issue with spacedesk.
PC:
– Windows 10
– AMD Athlon X4 860K
– NVIDIA GTX 750 Ti (latest driver)
– 8 GB RAMTablet:
– Samsung Galaxy Tab A9+
– Connected via USBProblem:
When I move the mouse over any application displayed on the tablet (Steam, Chrome, etc.), the application’s CPU usage jumps from around 2% to 40% while GPU usage stays almost 0%.Could you please provide:
– an older Windows Driver (2.1.47 or 2.2.04),
– the matching Android APK,
– or any way to enable hardware encoding / GPU acceleration?Is this expected behavior? Is there a way to enable GPU hardware encoding or reduce CPU usage?
This only happens when I move the mouse over an application on the tablet display. Moving the mouse on the desktop does not cause high CPU usage.
Thank you.
