Since having the render device lost error I’ve been paying a lot more attention to GPU temperatures and GPU usage. My RTX card seems to be very well cooled and thus the temperature part is boring but I noticed I always had long period of ~95% GPU usage that was a huge anomaly for the game.
The hero select screen is maxing out the GPU even though the game itself doesn’t while running at ~290 fps.

Fixing whatever this issue is should drastically reduce the number of render device lost errors for everyone. (Almost all of mine happened during this time or during the PotG.)
