Moving a water body lowers performance on the engine. The fps drop from 120 to 30 and ms spike from 8 to 30. This issue occurs in 5.0 Binary and 4.27 Binary on Windows. On Mac, FPS drop and ms spike when dropping the water body but not while moving it.

Actual Result: FPS drop from 120 to 30 and ms spike from 8 to 30
Expected Result: FPS and ms either do not change when moved by not rendering water until object is "dropped"
