Thanks for your interest in the game!
The game runs great on Steam Deck and currently supports phone-based tracking. However, SteamOS uses Wi-Fi power management by default. This feature groups network packets together, which causes noticeable latency for real-time body tracking.
To ensure smooth and accurate tracking, Wi-Fi power saving must be disabled.
You can do this in one of the two ways below.
Press the Steam button and open Settings
Go to System
Enable Developer Mode
Open the new Developer tab at the bottom
Disable "Enable Wi-Fi Power Management"
Restart your Steam Deck
Switch to Desktop Mode
Open the Konsole app
Enter the following command:
sudo iw dev wlan0 set power_save off
If you don't have a sudo password, you will need to set one first.
