Phoenix render time optimization question

[PIXELBOX_SRO]

Hi all
is it possible to cut down the rendertime of Phoenix fire and smoke effects in vray somehow so they get more close to scanline rendertimes??
I find the vray rendertimes quite animation prohibitive.....its absolutelly crawling.
I know its probably due to GI but still the difference between SCANLINE and vray is absolutely drastic :-/
Or am i missing any important quality setting in Phoenix which would optimize the result at least a bit?
Thanks a lot for reply!
Best Regards

well, i just gave an answer in the big smoke thread
the image sampler is the first suspected. try with fixed sampler and compare to scanline.
