Yeah, same. Also know the reason for the performance drop: Not physics, bad Lighting Rigs. Most/All of the Lights are Point/Force Pixel, so it's practically guaranteed that two or more Lightsources overlap on one or more object (Person atoms especially).
@Trucino: When one or more lightsource(s) overlap on an object (i.e. an area of the surface of the object is lit by two or more lightsources), performance tanks.
Drastically. Try disabling lights & watch effect on performance - I managed to go from 12fps in VR to >45fps merely by disabling lights and/or converting points to spots (with suitably small aperture, ie. at most angle <50° - goal is to tune the spots such that their cones do NOT overlap ).
And since you use point-sources rather than spots, overlap from multiple lightsources is practically guaranteed - that setup you use is ... suboptimal, to put it mildly.
Try the following:
1) Get PluginIdea's
Gizmo System - provides optical clue about shape & size of each lightsource's "field". Helps visualizing lighcones/radii.
2) Convert as many lightsources as possible to
spots - with small opening (angle), such that the spots don't overlap.
3) Maybe, instead of dozens of point-shaped lightsources with fixed orientation that need to be "on" all the time, use a handfull of spots that track the "Zone of interest" (Person atom(s)) & move with the "station" (Cowgirl on Couch, Missy in Kitchen etcetc). Probably best to parent a couple spots to a subscene & use
Lumination plugin - the plugin provides the tracking functionality, and you can move the subscene (with the lights) within the room to have optimal positioning for each animation/station.
4) Maybe also check out
CameraMan - basically a subscene with a camera that tracks a target (person atom) & moves with it. The lighting rig contained in the subscene is what's interesting. Maybe. Could be. It's actually made for MMD dance-scenes, but should also work for your scene.
5)
PluginIdea built some alternative, performance-friendly lightsources. Maybe interesting for you.
Nice scene, otherwise ...
