Hi Lior S, You have a lot of foliage in your exterior and my guess it is the AA sampling of this+the refraction of the windows that is giving you access render times. Vlado (Vray) recently added a subdivision multiplier as an addition to the already implemented GI subdivision multiplier to get around this with the latest update of VRay 3.0. You simply select the trees and reduces the subdivision amount. You notice very little to no difference in output but render times are reduced dramatically.Play with it until you find the right balance. My guess is that you working from Vray 2.0 ? A hack around this is to create two sets of lights. One with higher subdivision that your currently using for final renders and one with low subdivision..go as low as one for a base test and then exclude the tress from the lights with the higher subdivision and render with the lower set, and vice versa for the low subdivision lights, exclude everything but the tress. It sounds like a lot of work but is easily set up. Also in your render elements select sample rate and you should see that your windows at the minute are all red, which means your AA is having to do a lot of work = long render times. As your playing with the settings in the suggestion above you should see the color become less hot and more blues and greens should be the dominant color. Lets us know how it goes
