well i found out why planes and ships dont attack periscopes...
devs nerfed the visual sensors, can fix it two ways...
first reduce surface to real low value in sim.cfg however this has to ben ~10-50 for them to see a scope, while most mods are running it at 150-100. Default SH3 has 400 for the surface factor for visual...
I kinda figured they must have nerfed it elsewhere then...
It is in AI sensors, the AI visual sensor in SH3 has a sensitivity of 0.0000 in SH4 it has been nerfed to 0.300000
I suggest changing it 0.0000 in sh4 this will require re-doing sensors in the sim.cfg again, but GWX settings may work properly now...
Now planes and ships will attack scopes...
