I just ran a comparative test render with cycles on two different builds of blender r56315.
One compiled with VC 2008 and one compiled with VC 2012.
Simple scene with a high detail character
VC 2008: 18 Minutes 33 seconds
VC 2012: 16 Minutes 06 seconds
thats about 14% speed up
All on CPU, no CUDA yet.
I’d really like a benchmark for blender in order to compare physics, rendering and other features. Is there any?
By the way, the builds are both x64, the vs 2012 build was done with /arch:AVX and GHOST SDL instead of GHOST Win32 because of the odd crashing issue on Win 8 this isn’t optimal and brings a nasty cursor loading bug, but that’s just a matter of time. Most features seem to work perfectly.
Both builds and the prerequisite libs can be downloaded at my site: http://shadowrom.de
