Using High Res Terrain vs a Mesh

Hey everybody, so I’m wondering, is it okay to rely on a high resolution terrain procedurally generated from a program like WorldMachine for detailed landscapes and mountains (specifically mountains)? Or should you rely more on meshes to achieve the detail. I am going for some static close-up shots of the landscape. I am going to use the captured scene in the foreground of a photoshop painting for some concept art so I don’t have to worry too much about optimization. So long as the scene doesn’t exceed my memory threshold.

Or would it be better to use a lower resolution terrain and just use meshes for the detail?

Most games use a World Machine or similar tool orientated pipeline.

The landscape system has a lot of optimization features that you wouldn’t get with using a mesh for the terrain
