Nice splash =)
(Actually, not too crazy about the text on it. Seems every time I see the
words "POV-Ray," they're in a different font/color/size. Shouldn't there be
a consistent look, that fits with the logo?)

The difference in speed between the pvengine.exe and the pvengine-sse2.exe
is quite remarkable at least in my pentium4 machine. The latter is more
than twice as fast as the former.
Incredible what a big difference the choice of a compiler can have... :)

Using the SSE2 build, I still see weird artifacts in the beta 3 version.
I have posted to povray.betatest.binaries the arealight sample rendered
in 3.6 vs 3.7b3, this was rendered using the arealit1.pov sample scene.

Actually even more so when I discover that I accidentally included the MSVC
compile for pvengine.exe. Sorry about that, new binary on the way now.

Really fantastic improvement for pentium4!
Any optimization for AMD too...?
;-)

The sse2 version should run well on AMD processors that support it. Or you
could run Windows XP 64 on the AMD64 and see it fly* ;-)
-- Chris
* apart from the fact that it has SSE2, the AMD64 also had additional
registers which allow for a parameter-passing in register scheme and more
efficient code in general. this improves performance noticably.

BTW since you have both Windows and Linux running on AMD64 IIRC - did
you ever make a direct comparison (with the 3.6 codebase) of the
optimized Windows 64bit build with the gcc build on Linux? The
performance gain of 32->64bit on Linux is significant but i don't have
the direct comparison with Windows.

No, I don't think I did.

PS only just saw this posting because you (or your newsreader) removed the
beta-test group from the newsgroup line (I wasn't following this thread in
p.general since it was also appearing in p.beta-test).
