Followings are updates to my earlier P3D system settings shown in Post 239. Major changes are made to Scenery and Lighting, where the former improves Water Reflections and the latter enhances Shadows performance.
In addition, entry of [BufferPools] has been removed from the Prepar3D.cfg, as the simulator performs better without it than having the PoolSize set to zero.
Furthermore, the default water animation has also been replaced by REX’s Great texture.

Hello!
I see you have changed your tessellation setting from max to low, why is that?

Hi,
Not much difference and system runs better without it.
