```bash
sudo mkdir -p /usr/share/falcond/profiles/user/
sudo nano /usr/share/falcond/profiles/user/game.conf
```

```ini
name = "game.exe"
performance_mode = true
scx_sched = bpfland
scx_sched_props = gaming
vcache_mode = cache
start_script = "/home/ferreo/start.sh"
stop_script = "notify-send 'game stopped'"

### Convert AAC to PCM Audio using FFmpeg Script (Bash)

Source: https://wiki.nobaraproject.org/general-usage/additional-software/davinci-resolve

This bash script utilizes FFmpeg to convert video files with AAC audio to PCM audio. It iterates through all files with a specified extension in a directory, copies the video and subtitle streams, and converts the audio to pcm_s24le, saving the output as .mov files in a 'converted' subdirectory. Ensure FFmpeg is installed and accessible in your PATH.

```bash
#!/bin/bash
EXT=.mkv
mkdir -p converted
for f in *$EXT; do
NAME=$(echo $f | sed "s/$EXT//g")
ffmpeg -i "$f" -map 0:0 -map 0:1 -map 0:2 -vcodec copy -acodec pcm_s24le -f mov converted/"$NAME".mov

[Install]
WantedBy=multi-user.target
```

```bash
systemctl daemon-reload
systemctl enable --now power-dpm.service
```
