This is the kind of scene where turning off "Cache Irradiance" could be quite a lot faster.

thank's jure you can explain me where i need to turning off cache?
in really only in this render there is a time problem.
when the camera is global object the render time is good!!!
i've see this render in MWR, VRAY and KRAY....the best effect in < time is KRAY!!!

nothink...yesterday i've set kray on my second pc q6600 and from 10 pm to now 10 am i've rendered only one pic
on i7 i've rendered 3 image in MWR all 4000x2000 px multilight aptived ad 13 SL.
i hope to publishing the image so can see the work.
witout cache irradiance the render time is impossible. now i'm using cache and i've used a kray shader option for small part in crome but time is very very slow....
the big proble is that the client has see the preview in Kray but for tomorrow i think possibl send only render in MWR....the render remaining in kray unaffidable...15 min = 12h it's not possible...delete it in new version please

Could you send me your scene so I can check what's going on? Your render times are way too high.
