Did you already have patches we should apply? We typically give people commit
access after a couple of good patches.

Hi there,
With all major bugs an porting issues fixed we ran some tests with different
builds of blender for Windows 64 bit
Results can be seen here:

What seems strange is the fact that cycles performs best when built
According to the MinGW64 developers, the math library implementation is
faster for gcc. The simulations use openmp which is disabled in MinGW64 due
to their buggy pthread implementation which makes openmp hang when used
during pthread execution.

This sounds reasonable. So we need a lightning fast math library replacement
for MS compilers...
I'm just kidding, but the idea might be insane enough to try ;)
I am very satisfied with the speed improvement that MSVC 2012 has brought to
blender. I would love to see this in the wild. It could
Hi,
It's probably more compiler dependent than OS-dependent. Visual studio
does not compile the render kernel as well as gcc. I've been
developing with gcc, so that has some influence, and it's probably
possible to tweak the code such that it compiles faster on visual
studio. Thread management
You are right Brecht, I just tested with a GCC-built Windows version of
Blender an the result is comparable with that of Linux/Mac.
Thanks!

Not to start another OS debate. But...
I noticed that the performance of Cycles is very OS-dependent. With the old
rendering engine, the OS can influence the rendering time by ~10%. But with
Cycles, i am seeing a huge difference in performance between Windows and
Linux/Mac, where Linux/Mac is
