If you're using an antivirus/firewall, you will need to set exceptions for the game itself.
PSO2 utilizes an anti-cheat software known as GameGuard, which utilizes rootkit behavior to
scan your running processes and files. You cannot disable or limit GameGuard's access in any
way or form, as PSO2 will close if it detects this.
You will only need to register the game with the Microsoft Store if you are planning to use the Microsoft Store version of PSO2. Otherwise, you can skip this step.
Enabling Developer Mode
As a reminder, you will need to enable Developer mode in Windows 10 to continue - This is required to link the game to the Microsoft store in later steps.
There's a guide on how to do it here.
The Microsoft Store version of the game will not work without this!
Registering the game with the Microsoft Store
Once it finishes patching, download these two files: File #1 and File #2 Put them in the same folder where you installed the PSO2 Tweaker. Double click the CMD file to start the script. Wait until it says "Fixes complete!", then press any key.
It may prompt you about changing a policy - Just hit Y to continue.
If you receive a "permission denied" error in the red text, make sure you're logged in as an administrator.
What does this powershell script do?
This powershell script will check to make sure you have everything you need to run PSO2 (Required libraries, DirectX9, VCLibs, the correct files, etc), delete any leftover Microsoft Store files (Get that space back!), make sure everything is ready, then link the game to the Microsoft Store so that it knows that you have it installed.
This means that the Microsoft Store can see your game, but not modify it (No more file nuking!).
Launching the Tweaker
You may now play the game as is by clicking on "Start PSO2". \o/ However, there are more features that the PSO2 Tweaker that you can enable and install. If you wish to configure your graphics settings, keep reading!
Also, if you'd like to use my friend referral code, that'd be awesome! It allows you (and me) to earn unique rewards for leveling up! My player ID is 10003082 and will work on any ship, since I have a character on all of them. Thank you!
To configure the graphic settings for PSO2, click on the button labeled
Unlike other games, PSO2 has different preset graphics options that enable and disable certain settings.
These settings do not allow you to customize them completely, except for the post-processing settings
that you can enable from within the game itself.
Below are the following overview of the different settings that can be
configured in the PSO2 Settings menu:
Play videos on lobby screens
Displays whether the in-game video ads in the lobbies play video or not.
Select whether you want Fullscreen, Virtual Fullscreen (Borderless Window), or Windowed mode.
Select your preferred game resolution. Virtual Fullscreen ignores this and goes for the maximum
supported resolution based on the primary screen set configured by Windows.
Set your preferred max framerate as supported by your screen. You can even choose unlimited
which functions the same as vsync disabled.
This changes the scaling of the UI in-game. It's recommended that you don't touch this
unless you have a smaller screen resolution lower than 1280x720.
The higher the UI resolution, the smaller the UI will be. A custom setting can be selected
if you manually edited the configuration file. (user.pso2)
Setting enables the quality of your shaders. Simple shaders disables all post processing effects, Standard is
the default setting, while High Resolution displays all post processing effects. Standard and High Quality shaders
also allow for them to be toggled on/off in-game. Simple disables this ability.
Selecting your texture quality determines how your in-game textures look.
Compressed is good for very low end machines, Standard is the default, and
High Resolution allows for a very near HD feel.
Simple Render Setting
PSO2 uses different setting presets to display different graphic configurations. To play on low settings,
with everything disabled, slide the slider down to 1. Maximum settings can be set by sliding the setting
to 6, while medium settings can be achieved by selecting setting 3.
This slider lets you set the desired volume of the in-game music and concerts.
This slider lets you set the desired volume of the general sound effects.
This slider lets you set the desired volume of the voices your character and other
This slider lets you set the desired volume of the video ads in-game.
Once you have configured your desired settings, click on "Save Changes" to exit this menu.
