I'm having this annoying problem after updating my Premiere Pro CC to the 2021 version.
Every time I open a project, my computer slows way down for about 10 minutes, and in my task manager, I see that Premiere is eating 100% of my CPU. I've never had this problem before the update, even with lots of chrome tabs open, AE, Photoshop, and folders. But now, even if I close everything, I still have the same problem for about 5-10 minutes. Mouse dragging, everything laggy, and suddenly the percentage goes down again, and I can work properly.
Yeah I've seen this a lot with AMD users. I myslef have the same problem and it's beggining to osund more like a chance to drop this company once and for all and use other alternatives. There is foul play in every update and they are very behind on many things that shoul've been resolved by now.
