Render Performance


AnyDesk supports a range of operating systems and graphics hardware. Depending on the system, some adjustments may have to be made in order to get best performance.


Display Settings

Full Screen Mode is enabled by selecting Full Screen in the main menu during session or in the settings, Render performance is best in full screen mode. Using Direct3D by default, AnyDesk gains exclusive access to the GPU in Full Screen Mode providing latency near the monitors reaction time. As a trade off, tearing may appear.

Note: Direct3D Rendering gains exclusive rights to the GPU for a single display. Hence multiple sessions on several displays can only have one display in fullscreen mode. The second session must be in windowed Mode.

To have serveral seperate sessions on multiple displays switch the rendering mode to DirectDraw or OpenGL. This enables to capture.


Render Performance is highly dependent on the graphics card. If the session has poor performance, check whether another program occupies too much GPU resources. HD video streaming during session consumes high bandwidth and lowers performance. You can free GPU resources for AnyDesk by going to full screen mode or by minimizing the interfering application.

Hardware Acceleration

By default, AnyDesk uses Direct3D-Renderer. If you have problems with the display, select a lower rendering mode in the options tab. In the main menu go to Settings » Display » Hardware acceleration Try DirectDraw first, then disable hardware acceleration.

Note: No hardware acceleration is not recommended and will reduce performance. In Windows XP only Direct Draw rendering is available.
  • Applications that also access the network can lead to slower transmission.
  • Windows Server, Windows 7 without Aero and Windows XP require Mirror Driver to boost render performance. See also Mirror Driver
