Vray 3.4 for Sketchup VERY slow render

[gnome_mo]

Hello.

I'm fairly new to v-ray and having some trouble.

The question is: what is normal time to render this exterior?

I realize that my PC is not "Latest and greatest" bit it seems to me that this is too much.

(intel i5 2500 @3,6ghz , 24 gb ram)

Setup is sketchup 2017, v-ray 3.4

Settings are at high, 3000x1687, changed brute force to irradiance map min -3 max 0.

I have some Laubwerk trees with 30% leaves and vray fur as grass.

After 10h render was at 17%, moving 1-2%by the hour.

Most of the materials were sketchup default, few were v-ray integrated. No displacement, no bump.

Only imported glass because v-ray default glass renders glossy black for some reason.

No lights, default sky and background.

Sketchup file is about 170mb.

 

Honestly I can't figure whats wromg. I know that this types of problems can be from high rez textures or subdivisions, but I haven't imported any v-ray materials,, and my maps are low quality.

 

Any advice?
