Use the external console to execute commands (bootstrapper cmd window).

RivH_ Once you launch your specific game, press the key under ESC. This will usually be tilde (` or ~) or ² on AZERTY keyboards.

If you have a 60% keyboard you should press FN and ESC instead.

If none of this work for some reason use the external console as mentioned above
