Thank you for this kind of help Adobe!
Now everything is worse than ever!
After applying 6.0.2 no more jittering because no playback anymore having CUDA enabled! Fantastical Adobe! Black screen is a must while editing a video)))
So I keep smiling and for now moving to Apple Final Cut ProX.
Hope you can read and answer here Adobe guys!
Just FYI:
MBP Retina, os x 10.8.2, cuda 5.0.24, premiere pro 6.0.2
EOS 5DMKII and EOS 1DX footages 1080p.
