I have  a 165 hz display. It is a lot less severe when I put it on a 60 HZ screen. It still has very considerable GPU usage.
Comment 1 contact 2024-06-13 10:12:17 UTC 
I should explain: the first step is so you can have a system-monitor provided base reading of the GPU utilization.
Comment 2 contact 2024-07-04 16:12:47 UTC 
Can still reproduce this. Had system monitor in the background and my fans were going nuts. Was still not good, but a lot better when I closed system monitor.
