It's because of averaged normal on your low poly, which makes the rays not perpendicular to the surface. Just bake your floating geometry with a flat plane and it should be fine.

thanks, man but I'm confused can It would be great if you can elaborate it.

make a flat plane just for baking. After baking you can add in edges and adjust the shape as necesary. So three meshes. Game res mesh, lo poly baking mesh, and hi poly mesh. Game res and lo poly mesh share the same UV's.

Lot's of discussion about it here:

also marmoset has some tutorials for baking on their website with some dandy pictures to help illustrate what is happening.

thanks, man it worked (I made a flat plane according to you) you are saying after baking adjust the shape(see image)
