I have reworked RTPATHOCL synchronization code with the objective to remove UI lag. This work is on "new_rtpathocl_sync" branch.

@B.Y.O.B.: the WaitNewFrame() now takes zero time to be execute (be careful to not eat CPU time with too many refresh now). This should solve the problem of Blender UI lagging when doing view port rendering a complex scenes. Can you try it ?

All works on OSX..

Wow, I hope this will help!

Sounds good, I'll test it when I'm back at my PC in about one week.

Sounds great.

I merged the branch with the master so it can now be tested by anyone with the next automatic build.

Does this require changes in the addon or will it work in the next build out of the box?

It should work out of the box, you may have somewhat the opposite problem: too many screen refreshes because they are not timed anymore.

BTW, is there any interest in adding CPU (i.e. hybrid => CPU+GPU) support for RTPATHOCL ? It may be helpful on high end CPUs where the CPU is about as fast as the GPU (i.e. RTPATHOCL is currently GPU-only rendering).

It could be a good thing, especially with new high core CPUs generation.
I like the idea.
