Things with bad anti-aliasing:
The outline of the glow from the the MCC drop opening's shield. Also the white outlines appearing around one's gun when the gun overlaps the MCC opening.
The outlines on the nanohive's glow bubble. Also the outlines appearing around one's gun when the gun overlaps the nanohive's glow bubble.
The fire of an assault rifle.
Here is a photo of what I mean.

Textures:
Often slow loading with surface infrastructure and vehicles. Happens sometimes with dropsuit textures in the war barge.
Up close they often look bad on on surface infrastructure, sometimes zigzag pattern of pixels can be seen.

Special effects:
The white line effects (looks kind of like lightning) that happens when a precision strike is called. Can be seen when flying a dropship in the middle of a precision strike.

Lighting:
In the MCC interior sometimes the lighting flickers from bright to dark, like someone is turning a light on and off. This tends to happen when you walk from one part of the MCC to the next.
