I dont know if this issue is already discussed somewhere, since there are a lot of Anti Aliasing related topics here and elsewhere.

I noticed that some static objects have very strong shimmering on them while actually being static on screen. That means it occurse when there is no no panning, camera or aircraft movement (where without any AA one would expect shimmering to occur). Everything else seems fine. The issue is especially noticeable at night, where the area where an airport floodlight illuminates itself is shimmering. I also noticed it on cranes, poles or window frames. On some addon airports it seems to be spread all over the terminal, which is really a deal breaker. Back in FSX days i would assume the issue is "transparency antialiasing".

As soon as i switch away from TAA to DLAA or FXAA the flickering is gone, but this provides poor quality AA overall. Somewhere i read that switching of sharpening can help, but i didnt see a difference.
Another way to eliminate the effect almost completely is to run 4x DSR and use 2160p resolution on my 1080p monitor, but that brings my old 970ti to its knees.

I wish i could provide a video to show the issue but i dont have any recording software installed and if i use my phone to record from screen, the camera noise wont allow for it to be visible.

I am also not sure if this is a known and persistant bug in the way MSFS handles TAA or if i can do something by changing a setting i am not aware of. If anyone knows it, please help. 😉

I notice that too with TAA, that's why I use DLSS, which makes it better. DLAA or FXAA look very bad here, so those are out of question.

Lighting poles (and other narrow vertical objects) seem to be the worst for that in my experience.  Some sceneries seem to work better with DLSS and others with TAA.  

I 've found that overall DLSS gives better performance and TAA is slightly better visually.

Other methods of AA are not worth even considering unless you are using a very low end system from what I can tell.

I think the DX11 v DX12 argument is pretty much the same (unless you have a 4000 series card) so overall, DX11 and TAA produce superior visial quality and DX12 with DLSS the best performance.

Some things that shimmer in DX12 seem to be better in DX12.

Just a case of trade offs and personal preferences, I suppose.

But it makes instrumentation very blurry.  Not an option for me at all.

EDIT: links removed because they do not work, anyone knows a good video file upload site?

If anyone owns LatinVFRs Barajas and takes a look at the terminals with TAA on, you immediately notice what i am talking about, the shimmering is catastrophic there. But with light poles it is actually most bothersome and kind of ruins the image at night airports.

Against DLSS blurriniess try setting this in the user.cfg:

PrimaryScaling 0.500000 <<------ this is the most important value, with others you can experiement in game settings.
    SecondaryScaling 2.000000
    SharpenAmount 2.000000

should help. I use it for a crispier image with 0 performance loss, but I cant test it with DLSS because my card cant do it.
