I came to this section to say something about this issue, or more precisely a connected matter and I saw this thread existed already. The problem is actually much worse than elevated CPU usage - I’m seeing sharp spikes in GPU and motherboard temperatures. I’ve seen it jump from about 130-140 degrees Fahrenheit to almost 190 in a matter of seconds (GPU - the motherboard runs about 10 degrees lower)! I had to add an external cooling fan to this laptop or the system would be shutting itself down. Shutting it down has suddenly become essential to maintain system integrity. Not good guys. Not good at all. What could you possibly be doing that is forcing the system so hard. The editors do just fine with some spike when computing lighting but that’s to be expected.
