Same problems on a Mac Pro quad core, 16 GB, 2 x SSD Raid 0. Playing in Lion 8 layers with png 960 x 540 on a composition 3840 x 1080, it plays first 3 layer on 59 fps. After I activate next layers 4 to 8 fps goes down to 18-20 and animation on images are not smooth anymore. The output resolution were HD at 60Hz. And even without activated another screen output the situation was the same. The live camera was also like in slow motion. With maximum 3 layer everything is fine.
Same computer on win7 bootcamp at HD resolution 50 HZ, it start from 50 and after the fourth layer was activated the fps goes down to 20-25.
Nothing is changed even if I turn off effects.
Any clue?
I have try also in Milumil and everything looks perfect except the fact that the clips has no animation. But the live camera looks all right even with 10 layers.
Any help please? Because Resolume plays an important role in our productions. I attached a picture to explain better our configuration.
