Also, if cpu draws too much power, you will not get the dynamic power boost. Try to limit your cpu wattage. The dynamic boost is up to 15W, depending on how much power the rest of your system uses.

nvidia-smi -pl POWER

This will probably not work with recent driver versions, but might work with 525.

It works when set up with flatseal.

I thought compression would not help much with disk space as well. I believe it depends on the use case. After switching to btrfs and enabling zstd compression, my Arch install reduced from 100GB to 60 GB in terms of used disk space. Most of the savings are from documentations of development packages.

If your dGPU supports rtd3 power management, it should (almost) completely power off when not in use. For me the battery life changes a lot: is something like 2 hr vs 10hr battery life with the GPU off, which is very noticeable.

Well, most (if not all) freesync monitors flicker when the frame rate changes. You are probably jumping from 48 to 120 or similar. You can use freesync only for fullscreen apps on kde plasma if that works for you.

Google proton ntfs drive external. You need to add some mount options for the external ntfs drives and symlink the compatdata folder to a linux partition. After you do this, it will work seamlessly.

On my headphones, you can either use LDAC with one device or SBC/AAC with two devices. I can only change it via the app. Is there a similar setting for you?

Any way to see which bitrate is currently being used? I know you can set it to use only 909kbps, 606kbps or 303kbps in the wireplumber config, but I am curious which bitrate the adaptive mode (usually) uses.

I have a dell G15 5525 with rtx3060. No issues besides the general Nvidia driver issues. You can check the Arch Wiki.
