Getting Started & System Requirements
Phantasy Star Online 2 can be installed via multiple methods, but for the sake of this guide, we'll only focus on 2 of them.
Please make sure that your system is capable of installing PSO2. You can do this by checking your system requirements against the minimum requirements below.
| OS: | Windows 10/11 64bit ※As the game uses a 64bit exe, 32bit versions of Windows are no longer supported. ※Windows 7 & 8/8.1 are not officially supported and SEGA makes no guarantee that it will work on Windows 7 or 8/8.1. |
|---|---|
| Processor: | Intel Core i3-4150 or better AMD Ryzen 3 1200 or better ※CPU must have the AVX instruction set or it will fail to launch PSO2. ※2nd generation Core processors (Sandy Bridge, Sandy Bridge-E) may work as well, but your progress may vary. You can check to make sure that your CPU will work by running this program. |
| Memory: | 8 GB RAM or higher |
| Storage: | 120 GB SSD or higher (Formatted NTFS) |
| Graphics: | NVIDIA GeForce GTX 1060 or better AMD Radeon RX 580 or better Intel Arc A580* or better |
| Direct X: | Direct X 11 or better |
| Additional notes: |
A high speed broadband connection is required. Storage and graphics requirements will change without notice. |
*Intel Arc GPUs are untested and may not even work properly.
Various Methods of Installing PSO2
| # | Method | Description |
|---|---|---|
| 1 | Via the Tweaker (Fastest) |
By installing or downloading the PSO2 Tweaker, an 3rd party launcher that we've created, you can allow the Tweaker to download the game for you. |
| 2 | Via the Official Launcher | Installing the game via the official launcher can be done as well. This guide however, will not cover on installing the game via the official stock launcher. |
| 3 | Copying the game from a friend | By copying the game's installation folder from a friend (the folder in which NGS is installed) on to a large enough SSD (at least 120GB or more), the game can be played without having to install the game. The drive must be formatted as NTFS, due to file size restrictions. Playing the game on exFAT causes severe stuttering issues. |
As stated before, this guide will only cover using the Tweaker to download & install the game.
Prior to the graphics update of March 2021, there was a torrent install method. This method is officially deprecated and thus no longer available.
