A little update; still working on it.
Rendered @ 640x480; Physical sky + sun; simple plane & bump map.
For some reason dielectrics now clean lightening-fast (at list while I was doing those water tests). The image's been rendered at 640x480 for about 15 minutes and reached SL around 10. It was almost clean at SL 7.
Also did 40 frames(400x300; SL7) for yesterday's animation in less than 2 hours - and it's so noisy only because I had to compress the images to make sure the final .gif is not too big.
There's NO WAY I could render that image above in 15 min. on 1.7 (and believe me, I know what the word "SLOOOOOW" means - I am a proud owner of slowest machine of the Maxwell comunity

)
Could it be the power of V2?
So, what do you think?
BTW, I keep having serious problems with setting the sun position - I'm using a GPS navigator in Studio (moving the sun manually) and the Sun keeps "running away" & "jumping around"; so, not only I can't set the desired position of the sun, for example, I can't set it to 12:00 (in the very center.)
