This happens whether in eight- or 16-inch guns, the yellow site appears to be about 30 degrees off from the original bow on position. The white site we'll never meet up with the yellow. I have shot at a boat directly on the bowl but when I jump to the gunner position, I'm shooting at something approximately 30 degrees off the bow. I am able to hit the targets as usual.
I tried a B29 run, and everything worked fine until I was at 18,000 and frame rate dropped. The frame rate dropped to 2 this also occurred at 26,000. When coming upon a target I like to jump to the nose Gunners position to see how the plane is lined up on target again frame rate drops to practically 0. Fortunately, while in the Bombardier position and looking down the clouds don't affect frame rate
