The (High graphics) distortion effects from warping, explosions, and weapons impacts vs ships seem to stick around way too long (actual length seems proportional to framerate).
Also they're extremely distracting. was tractoring heph and i could see only like a sixth of him at any given time due to the effect.
Oh, also their position seems static relative to your screen, so that if it was in the center and you move away at 700 speed it stays in the center rather than staying attached to the object which caused it
No idea if this is a recent development or been like that forever; I just got a new gpu which can actually handle high graphics this week
