This is exactly what i was talking about earlier in this thread when i mentioned inconsistency in texture quality.
Some textures in my game look not as bad as this, but bad,others on the other hand look light years ahead.
My Juggernaut for example looks sharp and fantastic when compared to this, however my level 12 trooper looks almost as bad as this picture you have presented, which makes me think that some (not all) high res textures are either somehow bugged or disabled, or completely missing from the game currently.
I have to say though that this picture of yours looks really bad, to the level which really surprises me.
Also turn on AA, it will improve smoothing out edges and overall look.
