Mirko, ecco il testo tradotto un po' liberamente... ciao
Comparing both times and results found in "g4dual" posts (
http://www.lwita.com/vb/showthread.php?t=1690) i feel there's something wrong.
I tested the *very same scene* on three different machines:
- Notebook Asus Pentium M 740 Centrino 1.73Ghz, 512Mb Ram, ATI X600. Windows XP Home, Lightwave 8.3 e Kray 1.612
- PC Pentium 4 (640 3.2Ghz Prescott HT), 2Gb Ram, ATI FireGL T2. Windows XP Pro, Lightwave 8.5 e Kray 1.612
- PC AMD Athlon XP 1800+, 1Gb Ram, Nvidia GeForce DDR. Windows 2000 workstation, Lightwave 8.3 e Kray 1.612
Results shows how irradiances are totally different, even on different tests done on the same machine.
Notebook was the fastest and most coherent, P4 the slowest and more messy.
AMD performed very oddly.
So what ? Am i missing some settings here... i cannot find any logic in this; even if samples are generated randomly, i guess there's more than this here.
Here's the scene for you to test. i think it could be useful for debugging also...
