Since Version 1.4, the FreeRDP plugin uses hardware acceleration to improve the rendering performance of remote sessions.
This allows for a significant performance boost if your Mac has a dedicated graphics card but comes at the cost of draining the battery faster.

To switch back to non-hardware-accelerated rendering and improve the battery life of your Mac, please follow these steps:

  • Open Royal TSX' preferences
  • Navigate to "Plugin Settings" - "Remote Desktop" and make sure the "Plugin Settings" tab is selected
  • Switch the "Rendering Engine" to "Core Graphics (Quartz)"

Optionally you can also enable "Limit Mouse Event Rate". This will send mouse events at a more battery friendly rate but causes fast movements and scrolling to appear a bit less "smooth".
