Blender 2.32 (BF) on Unix (Mac OS X 10.3.3)
Moderators: jesterKing, stiv
ok many monkey with around 288000 v slow down blender so bad that switching between modes takes some seconds.
but also at 7920 v selecting polygones and moving them is slower than doing that with 3960 v!!!
with around 16000 its getting slower and slower. moving points is slow. rotating the cam is faster!
pretty sad to see that.
might it be a solutoin for you to use layers? wasnt blender also limited to a special amount of polygones two version ago?
claas

Yes ...that is sad
But hopefully someone would fix it at some point
Layers is a temporary solution. And yes...I use layers for
all my work weither it's 900.000 poly scene or 25 K scene.
But...sometimes with sophisticated film work it's not unusual
for the characters to hit 30 K for a single character with clothes
and normally that's not even an issue on the PC....
but on the Mac it slows down to a horrible state where it's
simply a nightmare to work with. This shouldn't be with
a superfast computer that at "least" equal the PC desktop with
all the trimmings.
Anyway - thanks for paying attention to this, now all
we can hope for is a fix.

First, have you tried ATi's newest drivers, under http://www.ati.com/support/drivers/mac/ ... plays.html ? The Radeon Display utilities also allow for application-specific tweaking of the OpenGL driver, maybe changing a setting or two there could make things faster.
Secondly, the speed has nothing to do with Cocoa or Aqua, for that matter.
OpenGL is made of C libraries, so using Carbon is just as fast. Cocoa can bring you some OS X features that Carbon can't, but that breaks cross-platformness quite fast.
Aqua, or rather Quartz Extreme uses OpenGL, true, but the moment an OpenGL application is running as the "active" application (the one "in front" where the user interaction happens) all of Quartz's OpenGL stuff is swapped out. Which means that the front-most application gets all the video card memory and GPU resources it wants. Apple would be stupid to not implement that ;o).
Going to full-screen would increase performance by at least 50% and once someone implements that, there should be a noticeable improvement. Also ATi is trying to update their OS X drivers more frequently now, so checking their website for updates is a good thing to do.

Michaelv:
Hi, I have been trying to use this for a week now. Can ypu give any insight whyI can nt get it to work
Can you post a simple copy and paste of the config file that you edited ?
Optimization on the scons build method is nonexsistant for darwin. I added
extra_flags = ['-pipe', '-fPIC', '-funsigned-char', '-ffast-math', '-mcpu=7450', '-mtune=7450']
, '-ffast-math', '-mcpu=7450', '-mtune=7450' are the additions.
and
release_flags = ['-O3']
to the if sys.platform =='darwin' section and it speeded things up nicely.
To find the correct machine type to add to -mcpu= and -mtune= use machine at the command line:

Welcome to Darwin!
[PowerBookG4 10:17:43am michaelv ] ~% machine
ppc7450 you'll get something like this.
Or you can just use the generic -mcpu=powerpc assuming you have a powerpc
For compiling the gameengine I added this to the SConscript file in solid:
elif sys.platform=='linux2' or sys.platform=='linux-i386':
defines += ['NDEBUG']
cflags += ['-O2']
elif sys.platform == 'darwin':
cflags += ['-O3', '-ffast-math', '-mcpu=7450', '-mtune=7450']
This adds the same optimizations to solid as the rest of the code.

as far as i know are most mac without retail ati cards.
this cards are NOT the same ati sells!
they are based on the same tech but apple tells ati
what to change and tweak and so they do!
so the retail drivers should not be used with the cards
shipped by apple!!!
this does not mean it can never work but we had hard times with
this when we worked with cards and drivers...

it works with most 3d-games in Apple...and they all run OpenGL
I don't see why it wouldnt work for Blender.
But as it is now...blender is horribly slow with OpenGL.
As slow as Blender would be with Microsoft's own Soft-OpenGL driver
without hardware accelleration....
...as a matter of fact & study...excactly as slow... O.o
Go figure...

I'm working on a 650 k Vertices scene just now with a G4 867 Mhz notebook which has an old ATI card, and it's still useable. And I have a 2nd monitor with a different resolution and frequency hooked on too.
There is a delay when switching from shaded to mesh mode but that's quite normal. And yes, it's slower than a 5k scene.
Now, a notebook card PC or Mac is always slower than a desktop one.
from ATI website :
*******
Display drivers and multimedia applications for notebooks with ATI graphics solutions are available for download from your Notebook manufacturer.
The display driver supplied with a given notebook has been customized for:
the built-in flat panel display
any other graphics or video options installed in that specific computer.
As a result of these customizations, ATI Customer Care is unable to offer drivers for notebooks.
*****
What that really means, is that the notebook card is slower (battery length) than the full flanged desktop one.
