Steam Deck - User set performance settings persist when switching to desktop mode

Your system information

• Steam client version:
• SteamOS version: 3.5.7 (Build: 20231122.1)
• Opted into Steam client beta?: No
• Opted into SteamOS beta?: No
• Have you checked for updates in Settings > System?: Yes

Please describe your issue in as much detail as possible:

Because of this issue https://github.com/ValveSoftware/SteamOS/issues/1245, I set my "GPU Clock Frequency" to "200" and "TDP Limit" to "4". This causes these settings to carry across to Desktop Mode.

Guild Wars 2 was getting ~10fps in the The Wizard's Tower compared to the locked 30 fps (in-game fps lock) I get when turning off "GPU Clock Frequency" and "TDP Limit" before going into Desktop Mode.

Steps for reproducing this issue:

1. Set "GPU Clock Frequency" to "200" and "TDP Limit" to "4" in Gamemode
2. Switch To Desktop
3. Launch (in my case) Guild Wars 2
4. Check fps
5. Repeat with the "GPU Clock Frequency" and "TDP Limit" to "Off"

There are scenarios where we want these settings to persist in desktop mode though. I don't think it's a bug.

I would rather consider this as a feature, tho the lack of a GUI in desktop mode makes this indeed anoying (but i actually use this to keep low power consumption in desktop mode)

have you tried to rollback SD Update to the previous installment? https://youtu.be/AN_-Bn1Elz4 in the comments is also a way to make it permanent - i can confirm it works and here's a documentation about it: https://rauc.readthedocs.io/en/latest/using.html#manually-switch-to-a-different-slot Still, use console commands on your own risk!

Unfortunately, my SteamOS-B is on 3.5.2-20231113.102 (3.5.5).

I guess I'll have to use the nested plasma desktop if I want to have different performance settings and keep the desktop mode running woth 200MHz and 4W.

Examples?

Running games in desktop mode (e.g. non steam games that I don't care about adding to steam, or for whatever else reason).

I found this thread looking how to set FPS limit in desktop mode, but if this "bug" is true then I don't need that.
