ok... So far i like v2, nice interface, not complaining about prices, etc..
cinema seems to work fine with it.

But..... I did some speed tests, with my old test scene:

winxp 32bit 1.7.1.
[05/September/2009 12:09:36] SL of 0.50. Benchmark of 48.949. Time: 28s

This is starting to scare me... i can imagine the speed is not x5, but v2 is slower??
that was our reason for upgrade... we bought 2 licenses today.

ps. i did this test on the linux 64 v1.7 as well.. that one had 25-30% speed improvement over win32 v1.7
so.. that means linux64 v1.7 is 35% faster then v2 on 32bit.. hmmm time to tryout linux64 v2.

Maybe i should have spent last 24 hours installing linux instead of trying to download v2 and buy licenses.. thats my feeling now.

you will need to compare the noise level of the enginges after the same amount of time.
you can not compare one s.l. level with the other.

Yes like mashium said time and sl mean nothing. Do both renders for the same time then compare the noise between the two. This is the only way to see the difference between 1.7 and 2.0. Visual comparison.

hmm well, dont have the old images anymore.

but after almost an hour i have loads of noise..
especially complex transparent area's seem to take longer... or around the same.
simple area's are cleaner more quickly.

I'm just wondering what you guys notice for the speed/noise improvement?

Well I only do product renders, and I get to an acceptable noise level about 2-3 times faster than I did with 1.7. sometimes more. Most of my product renders which average about 1500xx1200 are clear around sl 15 where I used to have to wait until about SL 18 to get to the same noise level. This usually means a few hours of time saved. I can not speak for interiors since I do not do those.

i was rendering a product in studio also, coffee machine lots of chrome/transparency,

but now im doing a children car seat without transparency and with a fabric with sss.

thats going really quickly
only 5mins and i can see nice detail on a 800x600, sweet!

SSS has improved a lot. You might have to tweak the sss from the old 1.7 to get the same look. It clears much faster though now. There is also single surface sss which is super fast compared to standard volume sss. You may want to try that if you are using sss on a single surface that does not have volume. The manual has a good explanation now of how to create sss materials compared to the old manual.

Camel, please post a few image comparisons for same time and let's check if there's something wrong.

I havent got the old one, but here is v2 after 1hour
cant show the whole pic.. classified project (as usual ).

Alright. I can make you sure running V1.7.1 for 1h won't be better than this. Bets?

That's not a fair, bet, Tom, and you know that
