Cinema4d R19's new viewport and Blender's EEVEE Cinema4d R19 version has a nice viewport update.

Is there anything different from Blender's EEVEE?

Or are high-quality viewports now becoming mandatory for DCC software?

Thanks.
R19 only have preview rendering mode (or advanced OpenGL). Where Eevee is a game engine view (close to UE4) Afaik, C4D have no plans on making an actual game engine view. But I could be wrong of course.
