Flickering emissive glow
I have made a material designed for this TRON-like look utilizing the emissive color of the material and it looks fine, however, when I zoom out the glowing edges of meshes start to flicker. Maybe it is because of really high emissive multiplier (120-140), but with a lower value there the material looks dull. Here is a screenshot of the material used on one of the actors: On some really distant ones the edges flicker way too much.

If that is the case then you can just leave it checked on since that is the default setting.
The way Temporal AA works essentially is that the scene is sampled then being blanketed with a 'counter-shake' like effect to smooth out the edges of your objects. This is probably what you are seeing when you apply the Temporal AA instead of FXAA.
The scene I have set up is using FXAA, and the results are as expected. You are never going to completely eliminate the aliasing on the edge of objects. Like you mentioned you can reduce this visual by increasing the resolution, but this in combination with Temporal AA can become an expensive process if over used. I found that messing with the material instance parameters and the post process settings yielded some pretty clean results.

One suggestion would be to blur the cubes in the distance to hide the aliasing until they come into the players focus. You can do this directly within your Post Process within the 'Depth of Field' section.
Try out these suggestions and let me know how it goes.
