- At the moment supported hardware: CS HD2

  Currently known problems:
  -------------------------
  - Display menus after changing resolution (Reboot required)
  - Display headers after changing resolution hd => fullhd (Reboot required)
  - Display infobar after changing resolution hd => fullhd (Reboot required)
  - Screenshot broken (With new driver and set resolution to 1280x720)
