Shimmering/AA downgrade since SU5 (in-game, not menus/overlays)

This user-end testing shows is that what the eye perceives as shimmer/jaggies/artifacts etc. can be produced by multiple things. I

I believe you are 100% right there are different types of shimmering. However there is the type which is expected due to the physical nature of computer graphics and there is the other type which only appeared since SU5 and which I personally find perfectly illustrated in its effects (my video at Santiago Chile) and in its root cause (my video with the cars).

For example:

There are definitely more jaggies in the cockpit and in menus than in SU4 2D and VR.

These are most likely and specifically for a totally different reason than the shimmering I’ve posted videos about. Here is:

Ok, you guys keep believing your monitor can display higher than native resolution. I’m done here. We can agree to disagree.

I agree with you, I’d laugh if someone was telling me this!

However, I can assure you your monitor can display a more accurate signal if you’re downscaling a 4K render into a 1K display, and actually, this is the minimum downscaling necessary to accurately sample the signal:

Nyquist–Shannon sampling theorem - Wikipedia
Nyquist frequency - Wikipedia

NB: antialiasing only consists in finding ways to sample the signal at a lower frequency than the Nyquist one in order to save computational power, while trying to minimize the sampling error, but it can’t fully eliminate the error.

There is still vibration/shimmering on tightly packed, high contrast horizontal lines (e.g., runway stripes viewed on the perpendicular).

And this is another type of visible consequence of the effects of the sample theorem, in a form which is known as Moiré pattern
