Public bug reported:
I got a new game and started playing it
It would run at over 100 FPS solidly some of the time and then cyclically dip
down to below 20 FPS for a few minutes
I determined that it was thermald trying to keep my GPU below 70°C
to determine this I sudo systemctl stop thermald
The game ran solidly and consistently with the GPU at 75°C
This is well below the specs set by the manufacturer and perhaps
unreasonably low for a laptop
But more importantly importantly I was given no indication this was
happening. I had to sleuth it out myself.
Perhaps it is impossible to determine good defaults for all hardware, I
don't know. However without an indication that this is happening there
will be a lot of people with a mysteriously broken experience. This was
extremely difficult for me to find and I had several friend who are
experts on linux gaming and video drivers trying to track this down. I
discovered it by luck and perseverance.
This absolutely needs some sort of indication and hopefully a way to
remedy it from the GUI. ideally it would set thermal limits that are
more in line with what the device is designed for and not a conservative
default if at all possible.
