So I did heard that too much water in terrain makes the game laggier. But not sure about if I change the color of it. Im just asking a question about does changing the color of the water make it laggier? Or no?
I wouldn’t think a colour change would affect lag.
It’s possible a Transparency change would though.
If you wanted to test it just make a huge place with Terrain water and mess with the color/transparency values to see if it makes a difference.
Your Studio or Roblox graphics settings may affect the look and lag of water as well.
