Are you running Shark using Parallels and Windows 7 on a Mac ?
Why ?
Your Shark license will allow you to install both the Mac and Windows versions, so run it natively.

If you are running Shark in Parallels, have you tried using Bootcamp instead and checked performance that way ?

I see no difference in performance when I run the same model on OS X or Win 7 Professional 64 on my systems.

Your machine should absolutely scream, with that kind of processing power and three raid'ed SSD's. A 30 MB file is not a large file, the issue is part complexity, but even that only effects rotating the part, panning and zooming. If panning and rotating are fast and smooth then the issue is probably a bad graphics card or driver.

I know very little about the Wacom Cintiq, but if it uses special drivers check that they are up to date, and talk to Wacom.

Have you tried connecting your system to a conventional display ? If that works without the patchiness and delays then the problem is probably with the Cintiq.

Hello Nick & Mike, thanks for the replies.

I should mention the 6-core CPU is 3.33GHz and the 3 SSDs are each Intel X25 120GB. I'm running Shark FX beta build 959.
I'm using Windows only as a test to see if the display problem also occurs with Windows 7. Nick, are you saying you get similar rotation performance with Mac and with Windows 7 -64? This is a complex part with a lot of rounds and fillets. Attached is a jpg of the Object Counts. My only problem with screen breakup is in Mac OS, and only with rotations. I may be getting over-aggressive trying to rotate faster than practical. The display breakup also shows up on other monitors (1680 X 1050, 60 Hz) - but same display board, though that board is also used with Windows 7 -32 under Parallels.

Mike, are you implying that the Windows code for Shark FX is significantly faster or more stable than for Mac? Sorry, but for patent reasons I can't publish the file. I think, with Parallels 6, I should get pretty snappy performance with this setup.

What is strange is that everything else has sped up incredibly, except for 3D zoom and rotation in SharkFX. Loading, saving, window movements, etc are fast, but rotations of complex objects in both Windows and Mac haven't improved much (and the display issue occurs with Mac). Attached also is an Xbench comparison of the earlier and current MacPros.

Anyone else getting display breakup with objects of this complexity? What OS?;
NO? What video card?

Thanks Much!

PRP,

Anytime you emulate an OS you are going to be slower than running an OS natively.


I don't run Shark on a Mac, so I can't compare speeds, but I do know that I run Shark on some fast Wintels, and they are pretty quick.

For a starting point I look up the cpu on passmark.com

for example, if you would get a 980x cpu you would be at a passmark cpu rating of about 10,000

Of course, this does not address any display settings...

Mike...

I would lean toward bad drivers, or a bad card, particularly if you are having the same problem with another display.

When I upgraded from 10.5.2 to 10.5.4 I had driver problems with the crappy X1600 in my iMac you can see what that looked like here:

I will try and test with a complex part on both systems latter today, but in the past the Windows drivers have always been better for Open GL than the Mac ones.

Your system sounds pretty new, have you called and talked to Apple ?
Have you checked Apple discussions to see if other people with your card are having problems ?

Additionally, if you can share the part that is giving you problems then I could test performance on my system. Private message me if you want.

OK PRP - I need to keep up : )

Good luck solving your problem

Is that something that a Quadro FX card would help?

Quadro FX - Full-featured, high-performance professional 3D graphics solutions for desktop and mobile workstations.

Mike...

I've read a few reviews concerning the drivers for the optional Quadros cards. Apparently they're terrible at best. The authors strongly recommended saving your money and not buying them.
