Let me introduce to you to the VR scene that I was doing with my students. Our faculty is very big, around 22000m2. Building without foliage contains 374190 faces. FPS is above 90, everything is baked. Real time lights are only in long corridors where you can turn them on/off. Mesh was separated for level streaming, but in the end there was no need for that because gtx980 handled it very well.

HTC Vive scene presentation (Serbian language), where you can see VR usage. Teleportation and scene interaction (teleportation, lights, doors) added via Vive controllers.
We have also done virtual presentation for students at our faculty, big space ideal for Room scale movement:
Also we had very some important guests from the Government of the Republic of Serbia. We have explained to them what virtual reality is through our VR scene and the power of real-time graphics with Unreal game engine. Impressions were beyond expected.
