Rockscapes - Procedural Textures
Procedural Materials could undoubtedly take a toll on your system, some basic optimization techniques could be:
-> Disconnecting the normal, and roughness channels.
-> Change displacement from Displacement and Bump --> Displacement Only
-> Reducing the number of subdivisions on your mesh.
-> Baking the textures
After making these changes, you may notice a significant improvement in viewport performance without much loss in quality. Remember that all of these parameters can be altered back for a final render. Hope you have fun with the materials
