So, a while ago, Unity uploaded a video of a real-time tech demo, showcasing mainly upcoming features like the HD Rendering Pipeline.
Right now, the video has well over 1 million views, and today, about 5 months after the upload, they released the entire project (2.4 GB compressed, by the way) on the Unity Asset Store for free.
All the Unity devs here can check it out themselves, if you don't want to import it or just want to see the build performance, I made an executable!
Download it here.
