Here's a little test render with the new pmc kernel in 2.47+,

This is with current 2.47, or this "+" is for newer build?

I don't know when it was done though, and forgot to check... (should have taken a screenshot too... :( )
It looked pretty clean after on hour though, i'm sure 2 hours would have been more than enough, and I used one GTX460 GPU.

We're still working on optimizing the PMC kernel, at this time it's difficult to predict, but I'm hoping we can get 2x speedup after the optimizations are finished,
in a few weeks with the big beta 2.5 release.
Bidirectional pathtracing (and PMC) should make renders like this one converge MUCH faster,
and bidirectional pathtracing + PMC is something we will be starting work on next, after 2.5 is out.
PMC + bidirectional will be ideal, it will be as efficient as the popular standard in CPU based unbiased engines (MLT+bidir),
and this combines with the power of GPUs should really take things to a new level.

That's fantastic news. Will bidirectional path tracing be ready for 1.0 or later?

great.

with with new pmc version 2.47+, the caustics seem to converge better than in the 2.47. Am i wrong ?

So you expect up 2 times faster with the opti, it's great. And after bidirectional implementation speed up again ?

this sounds good, both for octane and unbiased use.

i wish I could get my PMC render to look anything like this. all of my renders are blown way out when I try. Even with no lights in the scene. Any suggestions? I'm using linux, but it happens on windows too.
