Thanks Sebastian.
Good reminder about /arch:AVX2. I can post a separate binary package built with
this for people with newer CPUs if it shows a good performance gain.
Ok. Be aware not all modern CPUs support this though.
I'll also experiment with /fp:fast and see what the performance gain is, but it
sounds like it might not be a good idea for an OSG distribution package.
I'll try to get the Intel C++ builds working and I'll report back if I have any
interesting findings. The docs claim binary compatibility with VC++ 2015 with
/Qvc14. If there is interest in the CMake additions to support Intel C++ I can
push them to a GitHub branch.
Ok, I wasn't aware of this. Maybe it is a newer feature. Keep us posted.
If anyone can point me to good performance benchmarks that would be helpful in
sorting out the VC++ and Intel C++ options and performance.
You won't find something like this, at least not for what you are after.
When it comes to OSG we propably have to do this ourselves.
Thanks,
Stuart
Cheers
Sebastian
