We are using latest generation Mac Pros with OSX 10.4.11
The machine in question doesn’t even have a raid installed instead it runs with a 320GB internal SATA drive.
Yet, whenever I set the video preview output to the AJA Kona card it only renders with 11 fps (never faster, never slower, always exactly 11 fps) and once I switch it back to “computer display only” I end up with real time rendering.
Also the Kona Desktop feature does not work as I thought it would. The refresh rate on the broadcast screen attached to the Kona card seems to be extremly slow with OSX and Kona Desktop, the mouse does not move smoothly on the attaced broadcast monitor.
There is an installation of Final Cut Studio 1 on that machine, could that be a problem? (I would not know why, but you never know…)
