Controller optimizations, DirectX selection, quick save menu loading (v0.6.6)

Survivors,

a new update is now available!

After some users reported problems with the game's rendering, caused by hardware incompatibility with DirectX 12 (the game's default), there is now an in-game option to switch between DX11 & DX12.
The DirectX version can be changed through the settings menu.

Please consider that the game needs to be manually restarted after a new DirectX version is applied for the effect to take place!

Update to v0.6.6:

• The first tutorial steps now display the corresponding gamepad keys when starting the game with a gamepad
  
• The language menu can now be controlled with a gamepad
  
• The settings menu can now be controlled with a gamepad
  
• The controls menu can now be controlled with a gamepad
  
• Added a DirectX selection option to the settings menu (the game needs to be restarted to load with the new selected DirectX version)
  
• The save menu opens now instantly, even with multiple big savegames present (with multiple big savegame files present, the opening of the save menu took up to a minute of loading time, depending on the hardware and file size)
  
• Added default graphic settings for the Steam Deck (only for the default start up, when no save file for the settings is found)
  

Thank you for your ongoing feedback and support!
