Cuda x86 compilers out......octane future speed boost

Now that cuda is compiled for x86, I think it would be ideal that octane put this power to use....not sure what a cpu to gpu speed comparison would be, but surely a good i7 would contribute something.
How much work would it be to add this capability to octane?

We are looking into various options currently

if you compare luxrender and slg, a fast single cpu reaches about 15-20% of a fast single gpu. the question is, as this is still a cuda compiler, if it dumps the annoying texture limits (ram of course, but number of textures!), or not...

so much uncertainty and propaganda out there in gpu vs cpu......
if octane implemented this is would be the only real apples to apples test I have seen...
either way....should decrease render times....perhaps even allow for CPU network rendering along side GPU primary rendering...

Good to hear....look forward to what you guys come up with

I would be interested in this, running a Intel 980 hexacore chip with DT.
Of course I also think 1) instancing and 2) switch off primary visibility for objects, is a must before this...
