since CS6, I have the problem that the whole GUI starts lagging when I build compositions with higher performance requirements.
Starting with a very annoying delay on the mouse-scrolling, every action, especially in the timeline, is slowed down heavily. Even if there is no actual need of re-rendering anything in the scene.
I almost always work with the classic 3d-rendering.
Machine is a:
Mac Pro 2.8 GHz Quad-Core Intel Xeon
16 GB 1066 MHz DDR3
OS 10.8.2 (Problem already existed with 10.7)
NVIDIA Quadro 4000 2048 MB, GUP-Support activated.
I now it's not the fastest Machine on earth but it worked well with CS 3.
Is there anything known?
Turn off the disk cache....
It's already off and I also played with the multicore-settings.
