Hi, for 32-bit versions we use the 'official' MinGW pojects for the reasons outlined above (latest mingw-get-inst gets the necessary packages and is expected to run well). There are still no serious performance comparisons apart from one build here:
http://graphicall.org/918 where downloaders have reported good speedups for the cycles renderer. The builder has used maximum optimization though and I have found that this causes issues so I have lowered the optimization level for trunk. MinGW support has always been optional for blender, official binaries are built on MSVC 2008. We do have some users and developers compiling with MinGW though. A few obstacles to get it becoming a true alternative to MSVC on the developer level is the dependence of python on MSVC runtime, especially for debug libraries, and the reliance of the NVIDIA CUDA compiler that we use for GPU acceleration on the existence of MSVC on the system. And the speed of compilation which is terrible compared to linux gcc (I am very curious about the cause for that). Still it's nice for builders to be able to have 64 bit builds without a MSVC licence. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
