Playback lag suddenly just started in Premiere
Having problems with video not playing smoothly, especially noticeably when I scrub through the video, it's very jerky. This has only just started to happen so I don't know if something has become corrupted. It affects all video files, codecs and resolutions. Videos outside of Premiere appear to be fine. I even tried rendering the video in Premiere and it was still laggy. Version is 2015. I installed the latest version (2017) and tried in an older version and the problem is the same. Not sure what else to try?
I've also noticed that the picture is very slow to update when I'm colour correcting and making changes.
