Flickering lines

[Mephane]

Recently I got a new computer*, instead of AMD card (HD 6970) I once again am back to NVidia (GTX 780 Ti). I am quite sure my issue is caused by some setting in the NVidia Control Panel (or at least something outside of the game), but I have tried so many of them now that it must be something (or a specific combination) that is just too obscure for my limited knowledge. Basically, lines that are smoothed out by antialiasing are still subject to significant aliasing which flicker heavily under movement or camera rotation. I immediately saw this on the KSC buildings where all the edges at first glance looked like AA were simply turned off. Alas, I have tried and checked and AA is happening - if I really turn it off then I see that it is bare, unsmoothed pixels.

KSC with many edges still aliased despite AA being turned on (I see this regardless of whether I have it on application controlled or forced through the NVidia Control Panel):

So AA is doing something, but either it or something else is then messing it up. The most prominent example of this effect is the orbital line drawn in map view:

Before:

After:

This is different from the known issue regarding jagged orbital lines due to some antialiasing being enabled in the first place. If I turn it completely off, the effect is the same.

I am seeing similar effects in other games, too (Warframe, Elite Dangerous), so I am also quite confident this is not limited to KSP, but here I have a clear example that is also obvious in still images.

For reference, these are my current settings. I have tried out everything under the AA settings, from everything off to everything maxed, application controlled, override application settings, enhance application settings...

I found a Youtube video of someone else having the same issue in an entire different game (look at the handrails in the background):

I have recorded a few seconds of me zooming out of Jool, every single orbital line is subject to this effect:

Make sure your card's software is set to use application settings. If not, try changing the antialiasing, anistropic filtering and ambient occlusion settings.

I have tried all these things. Everything from all effects deactivated, to application controlled and even all maxed out (32x AA makes no difference to the alternating flickering colors of the orbital lines). I've even tried downgrading to an older driver as well as reinstalling the newest ones, too.

I am having this issue as well, have you come across any solution by chance? Thanks.

Nope, no solution so far.
