First Vray interior render - very slow render

Hello everyone,

I started using Vray for Rhino 2 months ago. In exterior scenes, I dont really have any trouble, but interior is a huge problem for me. I'm not sure how to set visopt properly, although I've tried several int. visopts from experienced users.

 

I'm rendering with this computer:

 

Intel Core i7 3632QM 2,2 GHz

RAM 2x 4 GB DDR3

NVIDIA GeForce GT645M 2 GB

 

And I need your advice on settings of this scene:

Scene is iluminated by Vray sun and Vray rectangular light over the stairs.

 

And my settings are:

I think these settings are pretty low and even then 2048x1013 takes 6 hours to render (although 1280x633 takes about 5 minutes only!).

 

I need better output (with ambient occlusion on, with more GI bounces.. and 6000x3000. That would be almost impossible to render.

 

So, can anyone tell me, where my problem is and witch setting should I change?

2048x1013 now takes 22 minutes, thats a significant improvement. I think it's much better, now i have to figure out what to do with rect. light, which is kind of blurry.

 

I really appreciate your help.
