When you start RIK, you can specify a custom command line. The main need for this is when using RIKdev's shortcuts, or creating your own shortcuts for that sake.
To add something to the startup command line, simply specify it like +map genesis or +movie_onlyCrosshair 1 and the game will add those settings. All ingame settings and commands can be specified like +<variable or command name>
Below are some shorthand alternatives to some of the more common settings, so you don't need to write the entire setting's name. These are only for use on the command line. Works both via RIKdev and custom shortcuts.
|+f 0 / 1||Alias of "gfx_fullscreen". Set to 1 for fullscreen, 0 for windowed mode.|
|+r WIDTHxHEIGHT||Alias of "gfx_resolution". Set to e.g. 1280x720 for 720p resolution.|
|+b 0 / 1|| Alias of "gfx_borderless". Set to 1 for borderless mode, 0 to force it off. |
Note: Borderless settings are handled only on startup, gfx_restart won't work properly. Either change the gfx_borderless* settings manually or add it to the startup command line.
|+bx WIDTH||Alias of "gfx_borderlessX". The horizontal offset from top left screen corner where the borderless window will be placed. Negative values are accepted.|
|+by HEIGHT||Alias of "gfx_borderlessY". The vertical offset from top left screen corner where the borderless window will be placed. Negative values are accepted.|
|+bt HEIGHT||Alias of "gfx_borderlessTaskbarHeight". When running in borderless mode it will compensate for the taskbar and remove the specified height from the resolution height. Default value is 40. This means that if you set gfx_resolution 1920x1080 and run in fullscreen borderless mode, the actual resolution will be 1920x1040. (1080 - 40, or whatever you set this to).|
