Optimized settings for Little Geometry & many particles

[emora]

Hello
I'm working on a animation with little.. or say not very dense geometry, but lots of fast moving particles (pflow)..
I am wondering about good settings in vray to get a fast rendering.. right now times are good, but I'm sure they can be improved..
light and small geometry, but fast moving particles..
any ideas would be appreciated.

thank you

Do you have motion blur there?

are the particles opacity mapped?

[emora]

yes motion blur..
no opacity maps.. low polygons..instanced geometry flying in and asembling an object.. kind of what sand blaster ( old plug ) did.
I'll post a still so you see what i mean..
