The issue is still present in 19.3-series drivers. It seems the black blotch around the center of the screen disappears if you deactivate post-processing. I also see some... BADLY misplaced shadows, but that should greatly reduced if you deactivate fog, or volumetric shadows. Or something. It seems to have something to do with environment mapping, or at the very least the lighting method the game uses.
Of all the games I've been playing, only Starpoint Gemini 2 has these problems.
