It certainly looks like there are some glow effects missing on the right side. Especially visible on bombers close-up picture, no engine glow on Nvidia HW for whatever reason.

Agreed.  This does not look like a good comparison.

Also, the scenes compared were not identical, so different effects are happening at the same time. Example: Fig3. Firing main cannon on LHS, and secondary railgun on RHS.

The additional bloom could feasibly be due to excessive brightness on one monitor compared to the other. The RHS looks to have much better colour.

Even so, the game is still in development, many of the graphical optimisations have not been implemented yet.

Did you bother to watch the comparison video linked in that post? I'm guessing not since it would completely invalidate your post. The screenshots are taken of the youtube video to easily show off the differences, not replace watching the video.

The video was of the benchmark, which is always different since its playing the game and the AI makes different decisions. I'm guessing you didn't watch the comparison video linked in the original post either.

I have, the camera work in the video was not magically better than the still captures that were taken from it.

If you look at recent benchmarks (not from the pre-alpha) you will see that there isn't that much difference between AMD and NVIDIA. Both have lightsources coming from each of the projectiles, and none of them are excessively blurry and distracting.
