Re: [Bf-committers] Cycles benchmark as promised.
Yay, I am done. http://download.shadowrom.de/Benchmark.pdf While doing this benchmark I tried to replace the math library used with the AMD libm implementation. This was actually slower on all systems (even the amd system) so I left these results out. The more I read about MSVC the more I have the feeling that the compiler doesnt optimize math functions properly. GCC seems to be way better on that. /Jürgen -Ursprüngliche Nachricht- Von: bf-committers-boun...@blender.org [mailto:bf-committers-boun...@blender.org] Im Auftrag von Jürgen Herrmann Gesendet: Dienstag, 4.

Re: [Bf-committers] Cycles benchmark as promised.
hi from these results it seems the fastest in cpu and gpu is mingw (with one exception for msvc). i think as a freelance 30-40% of render time reduction is a big advantage, has anyone tested the mingw openmp fix?
