Hello Shravanum,
Lumen is not possible for standalone VR.
Static lighting would be the most optimized. I think you could use one or two dynamic lights, but they could easily eat most of your performance. (Especially if they are shadowcasting dynamic lights)
Here’s a tip: Start with only a ‘Skylight’ (Source Type: Cubemap, set Cubemap)
This is a dead-simple way to illuminate your scene and will let you know if you have other performance concerns to take care of before lighting.
Also, you can change the editor preview quality level to better replicate what you’d see on device.
