-For some computers, smoothing all vertices at once will cause Blender to crash. Alternatively, some surfaces do not need to be smoothed. It's possible to select a section with the cursor in edit mode, and smooth these areas independently. +On some computers, smoothing all vertices at once will cause Blender to crash.

 +It can happen that models do not react to a change in this setting, as can be seen here.

 +One reason may be that the surfaces are not connected to each other. To join the surfaces together, select the surfaces together in ''Edit mode'' and use ''M'' for ''Merge'' to execute ''Merge by Distance''. The connected surfaces can then be displayed smoothed.
