To work around this (even if you aren’t sure you will be in a queue or not):
Before you hit play. Top right, Preferences > Visuals > Max FPS set to 30. Back out. Hit play.
I had 100% of my GPU being used, and when I did this to sit in queue, my GPU went down to 54%. Not sure if this is written anywhere else, but this is a great fix.
Once you are in game you can then change your FPS back to whatever you want it to be and your GPU won’t be overheated.
