Excellent, all I need now is an optimised build of yafray and I'll be laughing!

It certainly would be nice to see this become part of the official relese, whether it ever will, who knows.

Some people reported rendering artefacts caused by the optimisation in the past. Until we can be sure that the optimisation is not causing any problems, I don't think it will be part of the official releases.

doing those optimized builds would also require an official license of an intel compiler which is about 500€.

and thx to marty_d to set up this thread. it's my bad impression that, there are only very few people how actually use my build. that's why i won't do any further advertisement for it.

Your build is more used than you think

Thanks!

Yeah, I use it all the time too!
Sometimes, when I start a project, and most of what I do is modelling, I use the latest CVS version for the latest tools, but when I need to do more and more renders, I always revert to your optimized version, because it is *very* fast. Whenever there's a new release, I am always looking for your version (at the forums, etc.). So here's a big THANK YOU!!!

Just tried out your build and seems to run the game engine much quicker.
The frame rate has gone up, starts and restarts are faster. This is just what we need. Thanks for the build. Im on a low spec comp "500 Athlon"
and I would be interested if others notice simalar results.
I will let people know over at elYsiun where game engine speed has been
causing some grief.

Thanks again,

Bogey.

Don't give it up yet, you may already have your own sub-culture. And to get the idea into the official release we will need as much testing as we can get.

the problem is, i cannot really investigate this intel compiler stuff beyond simple compiler settings, because i dont have time for it. i signed up to the blender mailing list, but i havent made a single posting myself yet

as long as it isnt carried it to the center of development nobody will care about it.

I'm not a coder, but I think that for blender to get acceleration accross all platforms the code will need to be aligned. So if you have Christmas wish list and you want to get that animation project done before next Thanksgiving (US) <g>, the request you want to make is for aligned code.

From what I know, code and data alignment is really a non issue if you're coding in C. These are optimizations the compiler can take care of. For example, GCC enables code alignment from -O2 and up (which is the optimization level releases are compiled with). Doing things like that manually would be a waste of time.

There are more effective ways to optimize the code (finding the fastest math functions per platform, rewriting matrix ops in asm, ... or 'simply' write faster algorithms).

No problems with rendering so far. Also rendering times are now two-thirds of what they were. What's more is my current project is coming up on half a million polys and scrolling/zooming/rotating in edit mode is just as fast as a simple mesh (it was starting to drag on some operations with all relevant layers turned on).

So I personally would like to say Thank you, Thank you, Thank you, Thank you, Thank you!!!

i tried to get a thread going to this build as you can see before but the moderator locked it up twice glad to see you now succefully got a thread to that build . Why they locked mine is beyond me ,maybe they don't want windows blender to be faster that there macs

might it be possible to do a yafray optimized version too? I used the optimized build for some time now and it seeems stable. good work optimizing the code. I also sent an email to intel telling them they should make this build and upcoming ones for pr and free publicity reasons lol may be you all should .

Actually, they (Broken and Michel) repeatedly explained why they locked your threads.
