@Chris, it's not easy to use one line of code but not too hard to implement.
Must clean up the existed table if the original policy is passive policy 2.
Then parse&install pp1 on thermald.
I thought it's better to follow the upstream code architecture.

I have did the way you said, the one is affected and the one is not affected.
e.g. TGL and ADL platform.

Title:
thermald prematurely throttling GPU
Status in thermald package in Ubuntu:
Fix Released
Status in thermald source package in Jammy:
In Progress
Bug description:
[Impact]
* thermald prematurely throttling GPU
[Test Plan]
* Run game on the target machine.
* the FPS must not be throttled below 20FPS.
[Where problems could occur]
* better support for Passive Policy. currently passive policy 1 is supported
and it should have a bug if the machine only enable pssive policy 2.

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 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.
