Here is my guide for a better gaming experience. I've improved quite a few things. And performance is also technically tested and constantly further developed.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬⠀▬▬▬⠀▬▬⠀▬
What's new now:

➤ Texture streaming improved significantly, from 2 minutes after game start to 5-10 seconds (ssd).

➤ Clouds and Sky: Colors improved, more blue and not as gray. Clouds optimized in resolution. Look nicer and need less performance (distant clouds adjusted). True Sky activated.

➤ Water Flicker: Completely fixed by fixing the material reflection.

➤ Further lod adjustments and increases. Eg of buildings, Ai better lod, and details.

➤ Greatly increased grass distance, reduced density. no more popping.

➤ Cull distance increased, which means no more details popping up.

➤ Mesh distance from trees and bushes greatly increased, no more popping up.

➤ The performance in general should run better due to other minor optimizations such as lighting, grass and mesh adjustments in density. And other little things.

➤ Screen space reflexions optimized.

➤ Fog optimized in density and distance.

➤ Color adjustments and brightness optimized.

➤ Fov Optimized for smoother experience.

➤ Shadows optimized for better performance.

➤ Added Distance AO, the trees in the distance now look much better and not as bright anymore. Clearly visible in the 4 new screenshoots. I increased the fog density a bit.
