Commands for this game are pretty basic, and act a lot like Skyrim console commands, so you should not have a problem learning them. To use the console, press ~, then input the code and press Enter.

cl_fov X - Sets the field of view to X (default is 60).
e_MergedMeshesInstanceDist X - Changes the distance at which grass is animated (default is 20).
e_TimeOfDay - Shows the current time.
e_ViewDistRatio X - Changes the distance at which objects start to render (default is 500).
e_ViewDistRatioVegetation X - Changes the distance at which trees start to render (default is 500).
g_showHUD 0 - Disables HUD.
g_showHUD 1 - Enables HUD.
p_gravity_z X - Changes the intensity of gravity (default is 13).
r_Motionblur 0 - Disables motion blur.
r_depthofFieldmode 0 - Disables Depth of field durring dialogue.
r_vsync 0 - Disables Vsync.
wh_cheat_addItem [X Y] - Gives X amount of item with the Y ID.
wh_cheat_money X - Gives a certain amount of money. Confirmed not to work after release, but work at alpha and beta.
wh_pl_showfirecursor 1 - Adds a reticule when aiming a bow.

Note: The last one is pretty useless without a table of item IDs, but if it's working, the table will be discovered in no time.
