hmcs centered problem and tobii

[saar]

hey, 

i am using tobii eye tracker on dcs and when i am trying to use my hmd crosshair i have to look much further.

for example:

if i want to look on target that is 90' to my right i have to look with my eyes to the end of my screen.

idk if it is game problem or tobii calibration problem 

btw on other modules like the f16 and the apache the tobii works fine
