To use Octane in Linux, you must install nvidia-cuda-sdk package, and the latest nvidia-drivers.
I wasn't made speedtest to compare Win7 and Linux version, but I thonk it must be same.

OK, ok..
I'm just a compositor, not a programmer

I'm think the pass requires only remains two times more memory, but lot of rendering time. I think it becouse I found this expression in renderman DOCS:

result = SpecularDirect - SpecularDirectShadow + SpecularIndirect +
SpecularEnvironment + Ambient +
DiffuseDirect + Translucence ...

I have a few questions:
- with the rib import (in 1.03 beta?) will octane understand TCL scripts? (Like RIB-BOX in new renderman for maya 3)
- will octane render (and save) multiple passes - like caustic, shadow, reflection, refraction - in separate files, or multi layered image file, like EXR or ...

It will work with the latest NV drivers, on 64bit windows 7, and 64 bit linux too
