Env probe time interpolation causes rapid lighting changes

[SRSaunders]

Since commit ca3f8cd I have noticed exagerated, rapid changes in lighting of objects (e.g. floors, ceilings, doors, etc). This addition seems to be more of a degradation than an improvement. This is visible when moving throughout maps. I have tried to capture one obvious example in the bottom panels of the doors as seen below

With time interpolation:

Time.Interp.small.mp4

Without time interpolation:

No.Time.Interp.small.mp4
