Johnny Nash, "I can see clearly now......", seems to fit my experience.
I agree that while maneuvering, the tracers and hit sprites are less "vivid". Conversely, they are wonderfully animated and an adjustment that I think is worth the effort. Antialias, fogging, high screen resolution and low video contrast settings seem to be the culprits for those like semp that are unable to see them. I can say this, because in the past, I also was unable to even see the field gun tracers. Now, they are noticeably different but still clearly seen (most certainly at close range/ against dark backgrounds as Bustr has noted).
