Hey guys! 
I'm trying to do something like this guy was trying to do but in reverse (from 2d to 3d) what settings should I use on the calculator? Also, should I convert osu! sens to Fortnite and then Fortnite to the another games? Or osu! to each game? 
 

Thank you for the help, very appreciated. (Sorry for my English, it isn't my native language) 

 

Convert from Windows/Desktop to anything you like using 0% Monitor Distance Match. It won't improve 3D aim, but the sensitivity will feel the same and so it will be a lot more comfortable transitioning in and out of 3D and 2D.

Thank you, so, I should convert everything from Windows/Desktop right?

Thank you so much again
