Have you tried updating your video driver to 306.23?
Then I rendered the work area...the problem back again...Even I creat a new
project it's all the same.
When I import all the clips to the timeline I should wait like 1 minute then the playback window will show some still image.
And the playback of footage really good even I use 2:1 resolution to play R3D.But if I change anything like add or remove clips from timeline,the playback window will just frozen again.
Actually,at the very beginning of I run PR CS6,just open a new project with nothing,the playback window will stuck and have a screenshot of part of my wallpaper in it.I guess I could call it image ghost or something.
Could anyone tell me what's the problem?
