Do you think the difference between the new Mac Pro Towers is not necessarily the generation of tower but rather the Quadro 4000?
Can anyone with the latest gen Mac Pro using a Quadro 4000 tell us about their results running Lion and the two issues
1) GUI Bug - Lag
2) H.264 Editing
Since the Mercury Engine relies on lots of ram, high speed media array and the 4000 for optimal performance, I think its important to factor in these variable to the quiries from users with problems.
Can anyone tell me where they are getting their Quadro 4000 drivers from that run under Lion? The latest official driver is:
Mac OSX SnowLeopard
I read some developer drivers are around but nothing official from nVidia.
New Mac Pro with Lion Pre-installed
Quadro 4000 GPU
Updated Lion with all patches
Checked Java in system preferences and it installed the latest run time environment.
Ran the Adobe CS 5.5 Production Premium Suite Installer
Installed all Adobe updates. This included CS5.5.1 - All automated through Adobe Updates
Rebooted for good measure. No problems with anything.
Started up Premiere Pro and first checked to see if Mercury Playback Engine was enabled. I was concerned because I was relying on Lion to have the latest Quadro 4000 driver. Everything was enabled and working as expected. Cuda is also the most current one. No update available or needed. I also wanted to point out that this system has two 24" monitors and the Quadro drives the second monitor fullscreen very nicely.
Second test was the GUI Lag. I am comparing the Lag to an identical 12 core system running Snow Leopard. I want to say that first I have had limited time to compare in a measured way, but I noticed a substantial improvement on the Lion system. In the next few days, I hope to quantify this and post the results.
This system has no I/O card at this moment, but the other identical 12 core system is running a Blackmagic Extreme HD 3D+ card and I also will be posting some comparisons between the two systems in the near future.
