Reflection in water is pixelated

Hi All,

The reflection in a water plane is pixelated. I’ve used several assets and they all have same problems. Attached screen capture.

Increase the texture size in the water script

Found in their script 256x256. changed to 512x512. Still too pixelated.
Changed to 1024x1024.
Took a hit in 10 less FPS but will live with it.
