Hi Kei,
Thanks for getting in touch.
True terrain, is not a realtime tool, and was never designed to be. You can create scenes in this addon using eevee, there are certain modes that are not supported by Eevee. And this is what causes the sluggish viewport. Staying in cycles will stop this happening. The water also uses a volume, and this is also why you're viewport is slow with Eevee or the workbench engine.
