Thank you Boildown, I know Fraps, I have use fraps many years on my "EVE Online" nights :), but I am not sure if it will work on this, sure, I can try, but I´am trying to keep it simple just to take a picture.
And what about output / recording options! There must be an option to record just 1 frame in x seconds! Or not!
I am new to OBS, probably I am missing something.
