I believe that I may have been given more credit than deserved....... While testing we simply ran down a list of items over voice communication and chat, turning them off and moving sliders until we "stumbled" onto disabling "clutter in flight" rendering the best results.
I originally thought the "ShapeStd gamma" was a problem, and lowering it did help with flashing buildings to a small degree. Shadows disabled, again gave small relief, but disabling "clutter in flight" vastly improved what most had complained about.
It appears that listening to you ole
has an upside to it.
It felt good to help spot a solution for another.
As far as credit for the solution, it goes to the player that tested the results as I
pondered over what to do next.
