Are there any news on this issue? Anyone who has a fix?
Im using a 2017 MBP and i have the same problem on a 15.000€ iMac Pro and and a 30.000€ Mac Pro (both completaly fresh installs). Doesnt matter if its Catalina or Big Sur, if its PR 2020 or PR 2021.
Im getting sick of reading through forums every other week and trying differnt things just because it is almost impossible to work with any kind of video file or effect in any timeline. Every click/scrub inside of the timeline has 1-6 seconds lag/freeze before something happens. NOTHING is ever smooth and the CPU is spiking up to 700% as soon as i touch anything at all.
Ive tried so many things, i cant even remember them all. I only know that i didnt check up on one promessing lead that had to do with a change to the MOGRT library or something that seemed to have started this problem for many.
