I have some interior scene where rays/sample goes crazy high during GI precomp phase, like tens of millions. Once rendering starts rays/sample drops to few hundreds and then gradually falls to about 40 after a few passes (pretty normal for such scene IMHO). Rendered image cleans from noise rather poorly, again IMHO. Scene was carried through number of max versions, was converted from one render engine to another and is pretty messy. That huge initial r/s spike is still present even if i render with simple grey material override and/or hide all objects but walls. Scratching my head what could cause it? Any ideas?
