I’ve tested SU5 HF2 yesterday and my impression is that the AA visuals seem better now. If I were to describe it, it is as if before there was like a quarter or a half-pixel shift of something making the visuals less clear than ideal, and now all is pixel aligned properly.
However, I also believe the so called “shimmering” is due mainly to a bug I’ve documented:
[BUG] Shader code ‘viewdir’ and shadow/light rendering are inconsistent on right eye
Yesterday I’ve found this problem was still there, but with a slightly different angle. I’ll have to retry the very same aircraft to see whether they changed something specifically with this in SU5 HF2.
