Mac OSX and Mudbox 2011 performance slowdown

#1

I’m Using Mac OS X 10.6.4 and mudbox 2011, and oh god going over 750 000 polys is a “slow fest” really can’t sculpt anything over 750 000.

Zbrush can do 30 million.

Is anyone have the same problem with mac os x and mudbox?

I have a very clean system, spec is macbook pro dual core 2.66ghz, 6GB ram, geforce 8600m GT 512mb

I know OS X drivers for nvidia suck a lot, but this spec should allow me atleast 2 million poly smoothly.

Does anyone who work on laptop, have same performance limitations in mudbox?

Please reply guys, from your answers, will depend my switching to windows back again!

Thank you!

hmm think its your graphicscard… a 8600er isnt that fast…

#3

yeah i guess so, already building a pc with sli GPU …

#4

mudbox and the most cg apps wont use your sli…
but if you are using gpu renderer like octane or bunkspeed it will be really fast… :wink:

#5

Oh I see, I just assumed that mudbox is like any game uses heavily, but yea not even all games use sli
Does it use fullpower of cards with dualcore?

#6

mud is using only one gpu… i recommend a geforce 480 gtx…
or if you have the money the 5800er quadro with 4gig of ram…

Not all that slow though. I’ve been running with an 8800GT and can easily sculpt up to about 10 million polys on the PC. Not sure what the performance differences are between the two, but it’s probably not all that much slower.

It could be a driver issue. I had a problem with Mudbox 2010 on my laptop with a 9500. That had a nasty lag after every stroke and viewport movement, even though it was fast to actually sculpt. After being in contact with Autodesk support it became apparent that they don’t actually check with mobile graphics cards at all, so it’s not surprising they are a bit flaky. Luckily 2011 is much better on the laptop.

8600 GT --> 22,4 GB/s bandwith 128bit bus
8800 GT --> 57,6 GB/s bandwith 256bit bus

9500 M --> 25.6 GB/s bandwith 128bit bus

480 GTX --> 177.4 GB/s bandwith 384bit bus

so the 8600 is much slower…

OK, cool list, thanks Oglu. However the 9500M which is what I’m using right now is very similar in specs to the 8600 according to the list and that’s perfectly happy upto 10 mil on the PC (now in Mud 2011).

Oh thanks man, how about radeons? Or 295 I know it’s dual but it is a beast sort of isn’t it? I’m researching pc world again after 5 years of abandoning it for Mac… Feel generations behind
