Recommended Accessories

• MicroSD Card: 512GB or 1TB (You’d probably want the largest you can afford)
• SSD Replacement: 4TB NVME 2280
• eGPU: GPD G1 2024
• Charger: UGREEN 100W Charger

Windows Settings

GPD Win Mini’s ship with a program called Motion Assistant that handles your TDP, fan curves and more.

If you ever want to update it, you can find it on this page – https://www.gpd.hk/gpdwinmini2025firmwaredriver.

Recommended Motion Assistant Settings

• TDP Tab
• Set AC TDP & DC TDP or Unify – AC TDP is the TDP you want when plugged in, DC TDP is what you want when unplugged, or you can check Unify AC/TDP to use the same TDP for both. Make sure to click Apply to save.
• Auto Limit TDP & FPS Limit – if you set an FPS limit like 60FPS and check Auto Limit TDP, then MA will auto change your TDP to whatever TDP is needed to run your game at 60FPS.
• Check Disable CPU Boost – CPU Boost is awful for handhelds, turn this off.
• Check Enable Fan Speed and choose Fan 1 – personal preference, Fan 1-4 is different curves, choose what you like best.

• RTSS OSD Tab
• Check Change OSD – give this a hotkey, I like to use CTRL+0 – using this with a game open will cycle through the RTSS OSD to show FPS, and game information, super useful. Needs RTSS installed.

• Advanced Tab
• Check Start with windows and Minimized to tray

Per-Game Motion Assistant Settings

Open whatever game you want to have custom settings for.

Then, in MA, under the Process Profile section on the left, choose Bind and select that game’s process.

Select that process now on the left, and any changes you make to TDP, settings etc. will only apply to that game or app.

Improve sound with FxSound

The speakers on these devices are.. not great out of the box.

Thankfully, you can use a program called FxSound to get better audio at no cost.

Download FxSound from their website and then install it and open it.

Choose the Gaming preset from the dropdown on the top left and that’s it, you’re done!

How to factory reset/reinstall Windows

Unfortunately, since the Windows image is a custom GPD Windows image, you can’t just head to Settings and choose factory reset like you normally would on a Windows device.

Instead, head to GPD’s website and you can download their image, which you’ll need to flash to a USB drive and use to re-install Windows.

Setting up Syncthing

How to setup streaming to your device

Linux Settings – Bazzite

When you get your GPD Win Mini on delivery, it will be loaded with their custom Windows OS image.

You may want to install Bazzite, and you can do so following this guide.

The guide will show you how to dual boot, if you want, or just install Bazzite on its own.

Hotkeys

Menu+A will open the Steam Quick Access Menu.

R4 twice or holding R4 will open Handheld Daemon (HHD).

Disable CPU Boost

CPU Boost is enabled by default in Bazzite, let’s turn it off because it’s awful.

Open HHD > TDP > scroll down and change CPU Settings to Manual > CPU Boost set to Disabled.

I would also set CPU Power (EPP) to Low, but this is only useful for low TDP/low heat gaming.

Installing Gyro

There’s scripts you can enter to get gyro working on your device.

For the Win Mini 2024, open a Terminal and enter:

curl -L https://raw.githubusercontent.com/aarron-lee/gpd-win-tricks/main/win4-suspend-mods/install.sh | sh

For the Win Mini 2025, open a Terminal and enter:

curl -L https://raw.githubusercontent.com/aarron-lee/gpd-win-tricks/main/win4-suspend-mods/install_mini_2025.sh | sh

Improve sound with pipewire

Download the sink-eq10.conf file from here.

Place it into the following folder (if folders do not exist, create them):

home/.config/pipewire/pipewire.conf.d/ 

Set your volume to 100.

Open Terminal and enter the following:

systemctl —user restart wireplumber pipewire pipewire-pulse

Head to Game Mode > Settings > Audio and make sure the Output device is GPD Win Mini EQ.

Syncthing on Bazzite

Open the Discover store and install Syncthing Tray.

Configure Syncthing as needed.

Then, in Game Mode, in Decky Loader, install Steamdeck Decky Syncthing.

Select the “Other flatpak” option and enter io.github.martchus.syncthingtray.

Select On Game Mode and do not check the option to keep it on in Desktop mode.

Head back to Desktop Mode and add Syncthing to Autostart.
