I want to add, if you open the app in low resolution through the right click/info menu, it's so much smoother, but obviously that's not a feasable solution, it just points at that this is really a coding issue on Adobe's end. It‘s worse when you actually experience this yourself. What am I doing wrong Performance inside the timeline is mostly okay-ish, the real pain is. But on my 2018 MacBook Pro EVERY projects gets painfully slow after growing up to a few different timelines, Multicam, etc. There‘s a huge thread about Lightroom over in another Adobe Forum by frustrated iMac Pro owners. I love editing in Resolve and I happily replaced Premiere with it for most of the stuff I do. Other apps, After Effects and Lightroom Classic are also affected by this. Other software, like Final Cut, manage the same performance on the new machine on a 5k Display, but not Premiere. The same project on a 6 years old trashcan Mac Pro with 3xFull HD Displays runs absolutely like butter. Simply scrubbing the timeline, or moving a clip around is so sluggish and slow, it‘s just god awful. Sadly, this has absolutely not been the case. I just got a brand new Apple Mac Pro with the 32 GB Vega II GPU and was hoping it would finally bring smooth UI performance to my 5k Display in Premiere.
