Don't get me wrong.. I don't care about bidir
BiDir is still the only engine that seems to be able to manage complicated light paths...
Bidir isn't often used so it is not a lost
I guess is often used by people that care about the physics based realism.

This is just plain wrong. In fact it is exactly opposite since pathtracing+lighttracing+caustic cache can aslo do sds caustics(underwater, reflected caustics etc) which bidir can't. It also makes other features that would make the renderer more flexible very complicated to add

Here's an example what I wouldn't be able to render with bidir: download/file.php?id=6109&mode=view

Hi,

with complicated light paths I meant something like that:

I've added the blend-file to that post.
If you'd like you could try to find a solution to reach this result without biDir.
It would be really helpful for me to find something to speed those kind of visualisations up.

Thanks in advance.

Not sure what's the problem, just switch to gpu and enable lighttracing.
This way I went from about 163K rays/s to 5M rays/s in your scene.
