Hi, can someone help me setup the calculator to convert the same feel between games instead of 360, because some games just dont feel the same because fov cannot change 

For this you use the Monitor Distance calculations. Which one is best for you is impossible to say, but most favor either MDH 0% (same tracking speed of a moving target) or MDH 100% (same distance to flick to the edge of the monitor). Try them both and see which one feels best.
