A lot of shadows are stencil in first person.

This is less of a problem of that particular shadow and more of the shadow system itself..such as how some shadows are blurred in third but not first (civilian truck, the H-9's, some sign posts have sharp shadows and others do not)

It's been like this since the introduction in alpha and I don't understand why there hasn't been a drive to make all shadows render this way on the highest settings when it has been proven and even stated by devs in arma 2 that stencil shadows take CPU vs high setting which is GPU.

I don't know the technical reason but since it clearly looks better in 3rd person I don't assume this is intended behaviour.

Let's say this is a dupe of #8233 (or a part of it).
