Minor Issue -- took up a Spit 8 twice and there is a transparent effect around the center of the instrument panel that allows the ground/air textures to show through. It's like 2 pixels wide and changes colors with the color of the terrain.
Bigger Issue -- every time I fired my guns tonight, the sound lagged a tiny bit and I had small graphic stutters. It happened in a Mossie, twice in a Spit 8, and once in a 38J.
