This depends upon your hardware and not OCC algorithms.

You may ask about mesh support in OpenCascade. Without using it a lot, there is the OpenCascade's MeshVS framework that is dedicated to the visualization of meshes.

I advise you give an eye to classes StlMesh_Mesh, MeshVS_Mesh, XSDRAWSTLVRML_DataSource, MeshVS_MeshPrsBuilder, ...
