Actually yes you may well see a slightly lower POI with a strong sideways wind - the amount is modelled in the game (although you can't aim high to compensate for it).
The game just uses the same calcs as Chairgun - that's the best I can do without someone giving me a better set of equations.
I haven't tried it, but have you checked Chairgun to see whether it says you'll get a lower poi in a strong cross wind?
