I recently upgraded to PD 12 (from 11) and I'm noticing that the preview seems extremely slow... it's playing back exactly a 1 second chunk then pausing to render the next second, then playing one second, etc, etc. I don't remember this behaviour from PD11. It happens on unedited files I drag into the timeline and try to preview. Interestingly, if I open up the trim box, i have flawless playback in there while chopping files up.
It also doesn't seem to matter what quality I have the preview set at. It also doesn't appear to be a hardware issue... my CPU/GPU/Disk access is barely being taxed (< 25%) and there is plenty of free RAM (23% used of 16GB). Source files doesn't seem to make a difference, same behaviour with vids from my Canon P&S, Canon DSL and GoPro and a a friend's Nikon DSLR (so some .mov, some .mp4, with a variety of frame rates). It's really starting to annoy me while trying to edit. Anyone have any ideas? I've had a bit of a Google and a look through the forum and most reported issues with slowness seem to be definite hardware issues, whereas mine isn't. Is this related to the "pre-rendering" issue reported with Nvidia drivers? It doesn't sound quite like the behaviour reported with that bug.
Thanks!
