[Bf-committers] Cycles performance on Windows

[Jürgen Herrmann]

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 with MinGW64.
While the MSVC 2012 build perform equal or even better with smokesim, Blender internal and physics stuff.

I assume that the cycles code base is more or less optimized for gcc or gcc has some nice optimizations that fit well.
Is there any possibility to change this?

Best regards 
Jürgen
