I recently had my venerable Quad Core MacPro replaced with a new Octocore machine, because I use processing power like that.

Anyway, the Geforce 8800 GT seems to have an issue with support Quartz Extreme only on my secondary display.

My system profiler essentially shows Quartz Extreme as Supported on Display 1 and Not Supported on Display 2. When Mirroring is turned on, both displays exhibit the same symptom that made me first check the card, windows being dragged in the display in question moved jerkily and caused an increase in CPU usage.

FCP still runs though, but to play it safe I’ve placed both the Canvas and Viewer on the Quartz Enabled screen. Attempting to use NVinject and Natit drivers to supercede the default Nvidia drivers had no effect.

Anyone else on a Geforce 8800GT with similar problems? If you’re receiving a system with this configuration, check it carefully before the vendor leaves. I hope my case is an anomaly but FCP seems to work for now so I’m sticking with it until Apple or Nvidia reverts with a solution.

Update:Installing latest version of Kona’s Drivers 5.1 NDD Drivers resolves the issue. Probably caused by hardware conflict between AJA display output with the secondary display.
