Did a quick search and found this mentioned a couple of times but unable to determine the present status.
So not sure if its yet to be done , considered done, or something my end.
I get very strong shadow shimmer both in and out the cockpit.
Equally anti aliasing of shadow seems very coarse.
Flying over "wood land" is weird as the shadow kick in its like watching a shimmer line move in front of me with trees on my side darker and shimmering and trees on the other side some what lighter in colour. The line separating them is very distinctive.
All my graphics settings are maxed out.....I have no problem with FR.
My graphics card is set to application enabled where ever possible.
FOV is 100 ( its seems to be the same regardless of FOV).
