Agreed that right now, content needs more work than graphics.
I will say that the game is meant for resolutions above 1440 and on small (24" and smaller) monitors. The jaggies are awful outside these specs, even with 1.5 SS. Although, they are only an issue around/inside stations, the HUD, orbit lines, and the windscreen pillars of the cockpit.
Since they apparently can't "fix" this problem with AA, maybe they should have designed the graphics so jaggies would be less apparent (contrast?). It seems they just relied on >1440 res and small monitors.
