Premiere Pro using over 1000 (one thousand) % of CPU for simple tasks

Very simple rendering like slight color grading on one clip is moving at a crawl and taking up between 800 percent and 1200 percent of CPU making the machine useless while it's rendering. Is this normal? I don't remember PP behaving this way until very recently.

Premiere Pro Version 15.4.0 (build 47)

MacBook Pro (16-inch, 2019)

OS 11.5.1 (20G80)

2.4 GHz 8-Core Intel Core i9

32 GB 2667 MHz DDR4

AMD Radeon Pro 5500M 8 GB

Footage is 4096 x 2160 24p

1200%? Are you using Windows Taskmanager? For rendering you want the CPU and GPU to hit 100% but they may not. When playing back 1080P with an 8 core CPU the CPU should not be at 100%. If your system looks like the system in the video below during playback then your system is probably OK.

On Mac it's called Activity Monitor, but it's the same thing, yes. 1200% of CPU doesn't seem right to me either and simple rendering is taking an hour rather than minutes. Anyone else having this problem? Is it something like permissions or prefs?

Can you download iStats? 4K might choke your MacBook Pro.
