Steam overlay[7]

Camera/Mouse keeps resetting to screen center on Linux[edit]

     If you have issues with the camera resetting to the center of the screen in Linux, you might have the 'unclutter' program running in the background. 

You have to terminate it first with a task-manager or the following command in a terminal : kill `pidof unclutter`

System requirements[edit]

Drivers should be from NVIDIA/ATI to ensure proper functionality.
Caution when using an older or low cost CPU, such as Intel Celeron or AMD Sempron, their performance might not match this requirement.
