But I do have pre-SU5 videos clearly showing the nature of the shimmering, and I believe Asobo must know what are the type of optimisations they are doing with their rendering engine which is the root cause of this.
Here is to help…
[BUG/FEATURE] TAA is transforming road traffic into ghosts (self-cancelling moving pixels) - #3 by CptLucky8
Look closely at the trees in the 1st video in full screen (don’t look the cars):
No AA:
Then with TAA:
To me this looks quite obvious:
It seems they’re using the principles of PCM (Pulse Code Modulation) to trade spatial into temporal, that is displaying alpha blended pixels as opaque pixels instead, in selecting which to display per frame using a jittering pattern over multiple frame (hence the repeating cycle I’ve mentioned). This is not supposed to be visible when compensated with the TAAU accumulating pixels over time. However even pre-SU5, on the trees in these videos, you can see some jittering still with TAA. Now with SU5 they’ve changed the TAAU accumulation spread (and maybe thresholds) per Lionel’s video, and this most likely to me is the reason from the look of it, but just from the look of it of course and I can be 100% wrong as well.
