Feature request. It would be nice to add more visual effects to the first-person view, as the raindrops slide down the screen, the water that flows from the diving goggles as soon as you exit the water, splashing caused by the bullets hitting the water and the mud, and the reflections of the sun through the tactical glasses. Here are some examples from well-known games.

This allows the player to feel better in the environment, and not just behind a screen.
