Can confirm lagginess in Blender 2.80 release. Unable to check in 2.79 cause .blend is saved by Blender 2.80.
My setup is quite different: Kubuntu Linux 18.04, Radeon R9 290, AMD GPUPro 19.20 Driver.
Had rummaged through the scene and not found anything wrong, just mesh with 5K vertices and 2 iterations of Subdivision Surface. Blend file looks like imported from 2.79, but appending everything in clean 2.80 file didn't solved the issue.

The slowness is caused by the subdvision surface modifier.
This is a known issue and is being monitored on T58191
So there are already plans to resolve this issue.
