Rendering Time - Changed After Installing last build

Hi there!

I'm having a problem on rendering a model.
This model was last openned and rendered in solidrocks 1.2, and it took about 3hours to render.
After installing this last build, and saving the file, It is taking me, in the same settings, 24hours to render.
I'm using LC+IM present with interior.
I've already saved all model in a new file and tryied again but it all seems to remain the same.

Can someone help me? thanks a lot.

Yes...
Same version of vray and also All of the Vray 3.0 Goodies are off.
One thing though, is that dynamic buckets is on automatic, but I think it doesn't change a lot the rendering time, right?

Can it be any update solidrocks made to the material? While saving the scene?
The environment light is a vray dome, with an HDRI, with 32 subs. I've already changed the value to 8, but it doesn't help a lot.
Do you have any suggestion? Thanks!

Well,

Again thank you for your repply. Memory is set to 52 410 (I have 64gb of Ram) and the Default Geometry is set to auto.
Should I change it to Dynamic?
Thanks

Just a small update.

Changed to dynamic and render still takes a long time to render.
Changed to Brute Force + LC, Exterior, Good quality and is rendering fine, with normal speed!
Changed back to LC+IM, Exterior, Good Quality and again it takes forever...

Any inputs? Thank you soo much!
