The Console Within

To enable Console Commands, right click on "The Evil Within" in your steam library and select "Properties." Select "Set Launch Options." Enter "+com_allowconsole 1" withough the quotation marks.

When in-game, press "Insert" on your keyboard to pull up the console.
Once you've done this, you can enter the following commands:

R_swapinterval <NUMBER>

• Sets the FPS lock. Note that the numbers below are negative.
  
• -2: This is the default, set to 30 FPS. This is the officially supported frame rate
  
• -1: This sets the FPS limit to 60. Fully playable, although there may be quirks (we’re going to fix these).
  
• 0: This fully unlocks the FPS. We do not recommend playing above 60. We will not fix any issues above 60.

God

• God mode. You are effectively invincible, and certain enemy kill moves will not be used against you (Laura, for example, will not jump on you)

Noclip

• Allows you to walk through walls

G_infiniteammo

• Unlimited ammo (provided you have at least 1 bullet when you enable this)

G_stoptime 1

• Stops time. Note there is a bug right now where using this command causes a UI element to appear on screen. We’re looking to fix that in the near future.
  
• Re enable time with g_stoptime 0

Toggledebugcamera

• Separates the camera from Sebastian so you can freely move around the

R_forceaspectratio <NUMBER>

• Sets the aspect ratio. Default is 2.5, which is our official aspect ratio.
  
• 0 is full screen, but not ideal. 1.8 or 2 is probably most comfortable for those who don’t want bars.

Com_showFPS

• Turns on id’s native FPS counter

Startslowmotion2

• Slows down time

Stopslowmotion

• Disables slow motion
