In 2.79 when you make viewport rendering and in viewport you have many objects with high poly count - in render time blender remain object in bounds representation if you set it for them.
BUT
In 2.80 when you make viewport rendering and in viewport you have many objects with high poly count - in render time blender make those object not in bounds representation but full solid and viewport because of that star work very slow, i understand why slow - i make them bounds representation because of that BUT WHY 2.80 make them solid when it already setted as bounds? And in 2.79 all fine. Same scene, Same file…
Probably this is bug in 2.80?
