Hi Tom, thank you for jumping and helping us sort this out. As I described in my post reply, I like many others are having the exact same issue Nath is having, Just as he described, my same exact footage, timeline sequence etc.. plays perfectly in PPCC2019 and exact same footage, sequence is unusable in PPCC2020. This is also happening across multiple machines for me as well. Just to reiterate, Ive been on several calls and screen shares with adobe techs showing them direct first hand proof and examples that its a CC2020 issue and not our systems Ive even had CC219 and CC2020 open side by side and showed them CC2020 is unusable. Plays fine in source monitor, but timeline/program monitor is horribly choppy. I would absolutely love to get on a screen share or Facetime with you Tom so you can see first hand as well.
