Precomputed visibility. Very different number of visible meshes in ipad and pc.

[Ivan84]

I have a big problem with precomputed visibility on my device.
For example in this scene i have a maximum of 14 meshes drawn:


i went in the same place moving around a little to find the point where the maximum number of meshes is drawn in ipad and it is 55 in the same location.
I have another point where in pc there are 56 meshes drawn and in ipad i have 105 meshes drawn, and in general in ipad i always have more meshes than in pc.

What can it be? Is it some settings in the .ini files?
I set in base lightmass.ini an height of 1200 for the PlayAreaHeight that should be ok for my game.
